Lead software design, implementation, verification, validation, and production support while contributing to requirements, estimates, proposals, and project planning. Collaborate with engineering teams and suppliers, mentor junior engineers, and support prototype, pilot, and production programs. Travel to off-site locations as needed.

Develop distributed backend systems, APIs, and services for data acquisition, access, and processing. Write maintainable Golang services and a Python client library, optimize ingestion and retrieval performance, and collaborate with physicists and engineers to translate requirements into software. The role supports simulation and experimental data analysis in a fusion-energy environment and may involve safety-sensitive work, occasional travel, nights, weekends, or on-call coverage.

Design, develop, test, maintain, and integrate real-time and digital simulation models using C++ and Java. Build pre-processing tools and Python-based post-processing and data analysis libraries. Work with distributed system-of-systems simulations, third-party model integration, software build systems, version control, containerization, and simulation data analysis.

Design, build, and operate high-scale distributed observability systems for telemetry ingestion, processing, storage, autoscaling, and service provisioning. Own platform reliability, performance, capacity, and cost efficiency; participate in on-call rotations and resolve incidents through root-cause fixes. Develop automation, identify architectural bottlenecks, contribute to technical roadmaps and design reviews, and collaborate with infrastructure, product, and engineering teams.

Build and maintain end-to-end product features across React and TypeScript front ends, APIs, and supporting services. Collaborate with product, design, and engineering teams to simplify complex workflows, make architecture decisions, improve accessibility and performance, and troubleshoot production issues. The role requires strong product judgment, full-stack fluency, independent decision-making, and effective cross-functional communication. Work is hybrid, requiring at least three days weekly in San Francisco or New York City.

Design and implement mission-critical state estimation and control algorithms, simulation models, and software infrastructure for real-time and offline testbeds. Develop production-quality software, offline data analysis tools, and integrated test plans for SPARC control software. Collaborate with engineering teams to integrate software into hardware and software testbeds, while improving company-wide tooling and development processes.

Build and own full-stack systems for enterprise Retool administration, governance, security, and organization-wide scaling. Develop admin onboarding, projects, permissions, AI cost controls, telemetry pipelines, and multi-instance management features. Work across backend systems, data modeling, product infrastructure, APIs, and customer-facing interfaces while collaborating with engineering, product, design, and security teams. Own technically challenging projects end to end, emphasizing scalability, reliability, testing, code quality, and solving enterprise customer problems.

Lead design, development, modernization, and support of business-critical ASP.NET full-stack applications. Mentor and guide engineers, produce maintainable code, lead database design (Oracle PL/SQL), participate in design/deploy reviews, triage production issues, and assist hiring and team staffing.
