The Company’s market-leading solutions, enhanced by AI and machine learning capabilities, provide real-time and predictive insights to support electric utility, insurance and government agency customers.\nTechnosylva has provided critical solutions for the past 26 years. In 2022 the organization entered a period of significant growth and transformation with investment from TA Associates, a leading growth PE firm, scaling to about 225 employees and offering its product in over 10 countries. In 2024 General Atlantic, a leading global growth investor, announced a strategic growth investment in Technosylva to support the company in its mission.\nRole Overview\nWe are hiring a backend-focused Senior Software Engineer to build and optimize the high-performance services and compute models at the core of our platform. This role combines strong systems and backend engineering with advanced numerical and parallel-computing expertise. You will design robust services and APIs while also writing the highly optimized, concurrent code that makes large-scale simulation fast and accurate. It is an ideal fit for an engineer who is equally comfortable reasoning about service architecture and squeezing performance out of compute- and memory-intensive workloads.\nResponsibilities\nDesign, build, and maintain backend services and APIs (REST/gRPC or equivalent).\nModel, optimize, and maintain relational and non-relational databases - schema design, query tuning, and data integrity.\nImplement and troubleshoot inter-process communication (IPC, messaging, and service-to-service protocols).\nDevelop primary backend systems in C# and Java.\nDesign and implement highly optimized compute models in C++.\nApply synchronization, concurrency, and multi-processing techniques to maximize throughput and correctness.\nProfile, benchmark, and optimize performance-critical code paths.\nTranslate mathematical and algorithmic requirements into efficient, production-grade code.\nParticipate in architecture decisions, code reviews, and technical mentorship.\nWrite clean, testable, well-documented code and contribute to CI/CD practices.\nRequirements\nRequired\nStrong proficiency in C# and Java for backend development.\nStrong C++ skills for high-performance compute work.\nSolid understanding of concurrency, synchronization primitives, threading, and multi-processing.\nStrong mathematical proficiency - numerical methods, linear algebra, or applied math relevant to compute models.\nExperience with API design, database design, and IPC mechanisms.\nProven ability to profile and optimize compute- and memory-intensive workloads.\nPreferred Qualifications\nExperience with parallel and high-performance computing - multithreading at scale, SIMD/vectorization, GPU (CUDA/OpenCL), or distributed compute (MPI).\nBackground in scientific, geospatial, simulation, or physics-based modeling domains.\nFamiliarity with cloud infrastructure and containerized deployment (AWS/Azure/GCP, Docker, Kubernetes).\nExperience building and operating low-latency, high-throughput data or compute pipelines.\nWorking knowledge of observability, testing, and performance-regression practices for production systems.","description_format":"text","description_chars":3274,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Canada","iso":"CA","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Predictive Analytics","Navigation & Mapping"],"lifecycle":[{"event":"open","at":"2026-09-17T18:12:14Z"}],"visa":[],"liveness":{"score":62,"band":"ok","label":"Likely open","p_open":1,"p_active":0.828,"p_room":0.75,"age_days":47,"expected_fill_days":54,"reasons":["conf:4","velocity","win:late"],"computed_at":"2026-11-04T06:34:25Z"},"pay":null,"html_url":"https://alion.io/job/technosylva-senior-software-engineer-canada-only","json_url":"https://alion.io/job/technosylva-senior-software-engineer-canada-only.json","meta":{"generated_at":"2026-11-04T21:03:04Z","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":32594,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-05T00:00:00Z"}},"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":689495},"rest":"https://alion.io/mcp/rest/get_company?id=689495"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftechnosylva-senior-software-engineer-canada-only"},{"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%2Ftechnosylva-senior-software-engineer-canada-only"},{"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%2Ftechnosylva-senior-software-engineer-canada-only"},{"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/technosylva-senior-software-engineer-canada-only\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftechnosylva-senior-software-engineer-canada-only"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":1007529}},{"tool":"search_jobs","arguments":{"company":"technosylva.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":1007529},"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.
