We stand out as the only systematic and AI-centric bond manager in Canada. Our investment process is built and run by one integrated team of quantitative researchers, strategists and developers: asset allocation and security selection are driven by systems we build together, not by individual discretionary books. We've become known as “the nerds of the street” and proudly wear that tag.\nSince our founding, we've grown to manage over $1.9 billion in assets, an achievement driven by consistent top-percentile performance. You will join a team where developers, researchers and strategists build the investment process together.\nRole Overview\nAs our Quantitative Developer, Investment Platforms, you will own the systems that run our investment process end to end: the data platform that feeds every model and report, the research and backtesting stack, portfolio construction and trade execution, and the internal applications built on top. You will work as a peer to our quantitative researchers and strategists, not a ticket-taker, with a direct say in how models are designed, validated and deployed.\nWe build AI-native. You will use AI coding agents in depth throughout your workflow, from system design and implementation to testing, review and documentation, and you will help define how the whole team builds with them: the context, guardrails, evaluation and review practices that keep agent-assisted code production-grade.\nWhat will your typical day look like?\nOwn the platform architecture: Set technical priorities, make architectural decisions, and drive the evolution of our data, research and trading infrastructure with high autonomy.\nShip production systems: Take projects from conception to deployment, moving fluidly between refactoring legacy research code and building new capabilities from scratch.\nCo-build models with researchers: Work alongside quantitative researchers and strategists from hypothesis to deployment, turning complex models, signals and data requirements into robust, tested and monitored production code.\nBuild the technical foundation: Define development standards, testing and validation frameworks, and data contracts; mentor the team on best practices.\n Lead AI-native development: Evolve how the team works with AI coding agents (repository context, guardrails, automated testing and review workflows) to ship faster without lowering the bar.\nEnable the business: Build high-quality dashboards and internal tools that let the investment, operations and client teams interact with trading, risk and research systems.\nGuard data integrity: Own reconciliation, monitoring and alerting so that positions, prices and performance figures are right before they reach a portfolio or a client.\nQualifications\nSenior Development Background: 8+ years of professional experience building and maintaining production-grade systems, ideally data-intensive or numerical applications.\nCore Technical Proficiency: Expert-level Python, SQL/PostgreSQL, data modeling, and API design.\n AI-Native Development: Deep, hands-on use of AI coding agents (e.g., Claude Code, Codex, Cursor) in your daily workflow, and the system-design judgment to direct them: decomposing work, supplying the right context, reviewing and testing their output, and knowing when not to trust it.\n Quantitative Fluency: Comfort with statistics, linear algebra and numerical computing (NumPy, pandas or Polars), enough to read a research memo and challenge how a model is implemented.\nFrontend Flexibility: Ability to deliver fast, good-looking internal UIs using the most effective tools, from Jinja2 + HTMX to React.\nCloud Native Execution: Proven ability to design and personally execute complex schemas and infrastructure end-to-end.\n Infrastructure Expertise: Hands-on experience with Azure (or AWS/GCP), containerization (Docker/K8s), CI/CD pipelines, and Infrastructure as Code (Terraform).\nStartup DNA: You thrive in high-autonomy environments and can clearly communicate architectural trade-offs to researchers, strategists and other non-developer stakeholders.\nNice to haves\nFinance Domain Knowledge: Exposure to fixed income data, portfolio accounting, performance measurement or trade lifecycles is a plus to lead schema and pipeline design.\n Data Engineering Concepts: Experience with workflow orchestration (Prefect, Dagster) and high-performance formats like Parquet or Arrow.\n Numerical Optimization: Familiarity with portfolio optimization and solvers (e.g., CVXPY, Gurobi, MOSEK).\nMachine Learning Experience: Practical familiarity with data science workflows, predictive modeling, and implementing ML logic or reinforcement learning in production environments.\nWhat Nymbus Offers\nImpact & AutonomyDirect influence on trading infrastructure and real-time decision-making, ensuring you see the immediate effects of your work.\n\nHigh-Performance Team EnvironmentCollaborate with quantitative researchers, strategists and developers who welcome bold ideas and open discussions.\nEnjoy continuous mentorship from senior leadership, including our CIO.\n\nAccess to Cutting-Edge Tools & DataLeverage advanced market data, proprietary models, and sophisticated analytics to fuel innovation.\n\nCareer Progression & VisibilityA clear technical career path with the same seniority levels as our research and investment tracks, growing into platform ownership, technical leadership, mentoring, and representing Nymbus's technology to clients.\n\n Hybrid Work ModelBalance in-person collaboration (3 days in our downtown Montreal office) with the flexibility of remote work (2 days).\n\nComprehensive Benefits & Prime LocationCompetitive compensation package, including medical, dental, life, and disability coverage.\nCentral downtown offices close to restaurants, shops, and public transit.\n\nOur Culture\nWe value continuous improvement and rigorous analysis, nurture a supportive environment where every voice is heard, and are building a next-generation investment management firm rooted in intellectual curiosity and technological excellence.\nEqual Opportunity Employment\nAt Nymbus Capital, we believe diverse perspectives make our team stronger. We strongly encourage women and candidates from underrepresented backgrounds to apply, even if you don't meet every single qualification listed.\nApplication Process\nHow to Apply: Please submit your application through this page.\nInterview Steps: May include a coding assessment, technical interviews, and meetings with senior leadership.\nWe thank all applicants for their interest; however, only those selected for an interview will be contacted. No phone inquiries, please.\nJoin us and help build the systems that will shape the future of systematic fixed income and managed futures.

Nous sommes le seul gestionnaire obligataire systématique et axé sur l'IA au Canada. Notre processus d'investissement est conçu et exploité par une seule équipe intégrée de chercheurs, de stratèges et de développeurs quantitatifs : la répartition de l'actif et la sélection des titres reposent sur des systèmes que nous bâtissons ensemble, et non sur des portefeuilles discrétionnaires individuels. On nous surnomme « les nerds de la finance », et nous en sommes fiers.\nDepuis notre fondation, nous avons atteint plus de 1,9 milliard de dollars d'actifs sous gestion, grâce à un rendement constamment parmi les meilleurs centiles. Vous joindrez une équipe où développeurs, chercheurs et stratèges bâtissent ensemble le processus d'investissement.\nAperçu du poste\nÀ titre de développeur(-euse) quantitatif(-ive), plateformes d'investissement, vous serez responsable de bout en bout des systèmes qui font fonctionner notre processus d'investissement : la plateforme de données qui alimente chaque modèle et chaque rapport, l'environnement de recherche et de simulation historique (backtesting), la construction de portefeuilles et l'exécution des opérations, ainsi que les applications internes qui s'y greffent. Vous travaillerez d'égal à égal avec nos chercheurs et nos stratèges quantitatifs, et non comme simple exécutant, avec une voix directe dans la conception, la validation et le déploiement des modèles.\nNous développons de façon IA native. Vous utiliserez en profondeur des agents de programmation IA dans l'ensemble de votre travail, de la conception des systèmes à l'implémentation, aux tests, à la revue de code et à la documentation, et vous contribuerez à définir la façon dont toute l'équipe travaille avec eux : le contexte, les garde-fous, l'évaluation et les pratiques de revue qui gardent le code produit avec l'aide d'agents à un niveau de production.\nÀ quoi ressemblera votre journée type?\nResponsable de l'architecture de la plateforme : établir les priorités techniques, prendre les décisions d'architecture et faire évoluer notre infrastructure de données, de recherche et de négociation avec une grande autonomie.\nLivrer des systèmes en production : mener les projets de la conception au déploiement, en passant aisément de la refonte de code de recherche existant à la création de nouvelles fonctionnalités.\nCobâtir les modèles avec les chercheurs : travailler aux côtés des chercheurs et des stratèges quantitatifs, de l'hypothèse au déploiement, pour transformer des modèles, des signaux et des besoins en données complexes en code de production robuste, testé et surveillé.\nBâtir les fondations techniques : définir les normes de développement, les cadres de tests et de validation ainsi que les contrats de données, et accompagner l'équipe dans l'adoption des meilleures pratiques.\n Mener le développement IA natif : faire évoluer la façon dont l'équipe travaille avec les agents de programmation IA (contexte des dépôts, garde-fous, tests automatisés et processus de revue) pour livrer plus vite sans abaisser la barre.\nSoutenir l'entreprise : créer des tableaux de bord et des outils internes de qualité qui permettent aux équipes de placement, des opérations et des relations clients d'interagir avec les systèmes de négociation, de risque et de recherche.\nGarantir l'intégrité des données : prendre en charge le rapprochement, la surveillance et les alertes afin que les positions, les prix et les rendements soient exacts avant d'atteindre un portefeuille ou un client.\nQualifications\nExpérience de développement senior : plus de 8 ans d'expérience professionnelle dans la conception et la maintenance de systèmes de production, idéalement des applications numériques ou à forte intensité de données.\nCompétences techniques de base : Python, SQL/PostgreSQL, modélisation de données et conception d'API à un niveau expert.\n Développement IA natif : utilisation approfondie et concrète d'agents de programmation IA (p. ex. Claude Code, Codex, Cursor) au quotidien, et le jugement en conception de systèmes pour les diriger : découper le travail, fournir le bon contexte, réviser et tester leurs résultats, et savoir quand ne pas s'y fier.\n Aisance quantitative : à l'aise avec les statistiques, l'algèbre linéaire et le calcul numérique (NumPy, pandas ou Polars), assez pour lire une note de recherche et remettre en question l'implémentat...","description_format":"text","description_chars":16027,"description_truncated":true,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"French","level":"Advanced (C1)","optional":false}]},"benefits":["Hybrid work"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-09T15:32:01Z"}],"visa":[],"liveness":{"score":80,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.799,"p_room":1,"age_days":8,"expected_fill_days":24,"reasons":["conf:1","win:early"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/nymbus-quantitative-developer","json_url":"https://alion.io/job/nymbus-quantitative-developer.json","meta":{"generated_at":"2026-10-16T21:03:18Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":1780,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":1501074},"rest":"https://alion.io/mcp/rest/get_company?id=1501074"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fnymbus-quantitative-developer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fnymbus-quantitative-developer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fnymbus-quantitative-developer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/nymbus-quantitative-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fnymbus-quantitative-developer"}]}
