We seek to produce high-quality predictive signals (alphas) through our proprietary research platform to employ financial strategies focused on market in efficiencies. Our teams work collaboratively to drive the production of alphas and financial strategies – the foundation of a balanced, global investment platform.\nWorldQuant is built on a culture that pairs academic sensibility with accountability for results. Employees are encouraged to think openly about problems, balancing intellectualism and practicality. Excellent ideas come from anyone, anywhere. Employees are encouraged to challenge conventional thinking and possess an attitude of continuous improvement.\nOur goal is to hire the best and the brightest. We value intellectual horsepower first and foremost, and people who demonstrate an outstanding talent. There is no roadmap to future success, so we need people who can help us build it.\nTechnologists at WorldQuant research, design, code, test anddeploy firmwide platforms and tooling while working collaboratively with researchers. Our environment is relaxed yet intellectually driven. We seekpeople who think in code and are motivated by being around like-minded people.\nThe Role: We're seeking a senior developer to join our team. You will design, build, and operate large-scale data and ETL systems that power the firm's research and investment workflows. This is ahigh-autonomy role - you'll own critical systems end-to-end, make architectural decisions, and deliver solutions with minimal guidance. We need someone who is self-directed, able to lead themselves, take ownership of outcomes, and drive complex problems to resolution independently. You should be comfortable communicating across teams, articulating technical trade-offs to stakeholders, and mentoring others through code review and collaboration.\nWhat You'll Do:\nDesign, develop, and own backend services and data pipelines that process large volumes of data optimally and at scale\nArchitect data storage and processing solutions, including schema design, query optimization, and data modeling\nBuild and maintain APIs, messaging systems, and integration layers that connect data producers and consumers\nDrive technical decisions - evaluate trade-offs, choose the right tools, and define system boundaries\nTake ambiguous requirements and break them down into deliverable, well-engineered solutions\nDiagnose and resolve complex production issues - applying strong analytical and systems thinking\nImprove engineering practices: testing, CI/CD, observability, and documentation\nWhat You'll Bring:\n8+ years of professional software development experience\nStrong programming proficiency: Mastery of at least one major programming language (Python, Java, Go, C++, or equivalent). Beyond syntax fluency, you should understand language internals and be able to apply that depth to write performant, reliable code\nSystem design: Proven ability to architect distributed, scalable, and fault-tolerant systems. Understanding of common patterns - event-driven architecture, service decomposition, data partitioning, caching strategies\nData engineering: Experience building ETL/ELT pipelines, working with batch and streaming data, and handling large-scale data processing\nDatabase proficiency: Deep understanding of relational databases (PostgreSQL, MySQL) and familiarity with analytical/columnar stores; strong SQL skills including query optimization\nSoftware engineering depth: Strong grasp of data structures, algorithms, design patterns, and software architecture principles - applied in production, not just theory\nAPI design: Experience designing clean, well-documented REST/gRPC APIs\nIncident response mindset: Ability to diagnose production issues methodically, drive root-cause analysis, and feed into post-mortems and operational improvement\nAI-agent readiness: Openness to working alongside AI coding agents and LLM-powered tools as part of the development workflow - using AI as a force multiplier for code generation, review, debugging, and documentation\n\nNice to Have:\nPython mastery: Advanced knowledge of Python internals, concurrency (asyncio, threading, multiprocessing), performance profiling, packaging, and strong experience with frameworks such as FastAPI/Flask, SQLAlchemy, pytest, and mypy/type annotations\nObservability and distributed tracing: Experience with monitoring and observability stacks - metrics, structured logging, distributed tracing (OpenTelemetry, Grafana, ELK) - for diagnosing system behavior and bottlenecks in production\nDevOps practices: Familiarity with containerization (Docker), CI/CD pipelines (GitLab CI, Jenkins), and infrastructure-as-code (Ansible, Terraform)\nProgramming language versatility: Proficiency in additional languages that complement data platform work - C++ for performance-critical systems, Scala for distributed data processing with Apache Spark, or Rust for high-performance data engineering\nTeam leadership and management: Experience leading a development team, running sprints, conducting code reviews, mentoring engineers, and managing stakeholders' expectations\nMessage queues and streaming: Experience with Kafka, Redis, or similar event-driven architectures\nData orchestration: Exposure to Airflow or similar workflow orchestration frameworks\nFrontend / full-stack awareness: Familiarity with modern web technologies (React, TypeScript) for building internal UIs and dashboards\nFinancial services or quantitative finance background\nOpen-source contributions or a public portfolio of technical work\nSkills\nAI Agents, Incident Response, Development, Data Orchestration, Software Engineering, Front-end Development, Data Engineering, Python, Technical Leadership, API","description_format":"text","description_chars":5838,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Hedge Funds & Alternative Investments"],"lifecycle":[{"event":"open","at":"2026-11-06T02:28:45Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":236,"reasons":["seen:0","win:early"],"computed_at":"2026-11-06T05:58:05Z"},"pay":{"stated_usd_annual":187884,"is_top_pay":false},"html_url":"https://alion.io/job/worldquant-lead-engineer","json_url":"https://alion.io/job/worldquant-lead-engineer.json","meta":{"generated_at":"2026-11-06T17:07:47Z","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":31929,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-07T00:00:00Z"}},"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":95429},"rest":"https://alion.io/mcp/rest/get_company?id=95429"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fworldquant-lead-engineer"},{"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%2Fworldquant-lead-engineer"},{"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%2Fworldquant-lead-engineer"},{"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/worldquant-lead-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fworldquant-lead-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3851108}},{"tool":"search_jobs","arguments":{"company":"worldquant.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3851108},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
