Leads engineering and QA teams developing and modernizing software for K-12 nutrition programs. Partners with Product on agile planning, staffing, delivery, quality, incident response, and process improvement. Recruits, coaches, and develops team members while managing performance, career growth, and team well-being. The role requires overseeing legacy ASP.NET systems and migration to modern .NET, Angular, AWS, PostgreSQL, and CI/CD technologies.

Designs, maintains, and secures server, cloud, identity, network, backup, and disaster recovery infrastructure. Monitors system performance, manages patching and vulnerabilities, supports hybrid environments, leads migrations and upgrades, documents architecture, coordinates with vendors, and provides escalation support for complex technical issues.

Performs multiphysics simulations using CFD, FEA, and established models for fluid flow, heat transfer, and structural mechanics. Validates models against empirical data, interprets results, and deploys standardized workflows through AI-enabled tools. Partners with R&D teams to define modeling requirements, trains users, provides application support, and communicates feedback to core modeling specialists. The role also contributes to AI-powered scientific workflows and simulation-driven product design.

Conduct research and develop runtime calibration methods for superconducting quantum hardware, focusing on two-qubit gates, processor optimization, crosstalk mitigation, leakage reduction, and low-latency FPGA control. Collaborate with research, product, and engineering teams to translate quantum control advances into production software and communicate findings clearly.

Owns EDEN’s technical architecture across platform, science, and applications teams. Designs shared data contracts, procedural graph runtimes, optimization and AI-agent control loops, scalable simulation infrastructure, data platforms, APIs, and validation systems. Transforms research prototypes into reliable, reproducible products using Python, GPU workloads, parallel orchestration, cloud infrastructure, caching, sandboxing, and production engineering practices.

Leads manufacturing process development and production launch for nuclear reactor assemblies. Responsibilities include DFM/DFA, assembly process flows, tooling and equipment development, manufacturing documentation, mBOMs, configuration control, readiness reviews, floor troubleshooting, cross-functional collaboration, and mentoring engineers. The role supports hardware from engineering release through prototype, qualification, final integration, and scalable production while meeting rigorous quality and traceability requirements.

Lead Harvey’s Backend Platform team, hiring and developing engineers while defining technical strategy for shared backend frameworks and abstractions. Guide distributed-systems architecture across databases, caching, request handling, streaming, reliability, security, observability, and data access. Partner across engineering teams to scale infrastructure, improve developer productivity, and establish safe, maintainable codebases for human and AI-assisted development. Stay hands-on through architecture discussions, code reviews, prototyping, and complex systems problem-solving.

Leads the conceptual design, development, integration, and validation of precision optical systems and components. Responsibilities include lens design, optical modeling, Monte Carlo and tolerance analysis, design reviews, technical documentation, test-method development, and performance validation. The role uses Zemax, supports aerospace, defense, scientific, and commercial applications, and provides technical leadership and mentorship to junior engineers.

Lead the planning, design, and delivery of municipal wastewater infrastructure projects, including treatment plants, pump and lift stations, collection systems, force mains, and hydraulic analyses. Prepare technical studies, calculations, plans, specifications, reports, and construction documents. Coordinate multidisciplinary teams, support permitting and construction services, manage project tasks and client communications, and mentor junior staff.

Designs and owns silicon photonic components, subcircuits, and photonic integrated circuits from architecture and simulation through layout, verification, tapeout, and production handoff. Responsibilities include electromagnetic and optical-circuit simulation, PDK and PCell development, Python workflow automation, design verification, optical and system co-design, test structure definition, characterization analysis, and cross-functional collaboration with silicon, packaging, III-V, IC, and operations teams.
