Manager React Three Fiber Jobs (NOW HIRING)

Job Summary:
True Anomaly is a company focused on delivering capabilities for space superiority. They are seeking a dedicated Senior Full Stack Software Engineer to drive feature development and architectural decisions, working across both frontend and backend systems to enhance their spacecraft modeling, simulation, and ground control software.
Responsibilities:
• Own and deliver complex features end-to-end across the full stack, from 2D and 3D web-based frontend interfaces through distributed Elixir backend services, from technical design through production deployment and iteration
• Drive architectural direction across frontend and backend systems, establishing patterns and conventions that scale across the team and codebase, with particular attention to the boundaries and contracts between layers
• Proactively identify and address technical debt, performance bottlenecks, and reliability risks across the stack
• Set the quality bar through rigorous code review, championing testing practices in both React and Elixir, and writing code that serves as a reference implementation for the team
• Mentor and elevate junior and mid-level engineers through pairing, design discussions, and constructive code review that teaches, not just approves, helping engineers grow their skills on whichever side of the stack they're less experienced in
• Collaborate as a technical partner with product, design, QA, space operators, and astrodynamics algorithm engineers, contributing to system-wide architectural decisions with a perspective that spans the full stack
• Ship efficiently and iteratively, breaking complex cross-stack work into well-scoped increments while maintaining a bias toward completion over perfection
• Document decisions and patterns, ensuring the team's collective knowledge grows and onboarding becomes easier over time
Qualifications:
Required:
• 7+ years of software development experience with meaningful depth across both frontend and backend development
• Expert-level command of HTML/CSS and modern TypeScript/JavaScript, including nuanced understanding of performance implications and browser internals
• Deep expertise in modern React, including advanced patterns (compound components, render props, custom hooks architecture), state management strategies, and performance optimization techniques
• Strong proficiency in Elixir and OTP, including deep understanding of BEAM internals, process architecture, supervision strategies, and fault-tolerant system design
• Strong testing philosophy and hands-on experience across the stack, including Vitest, React Testing Library, and end-to-end testing on the frontend; ExUnit, property-based testing, and integration testing for distributed systems on the backend; you understand what to test, not just how
• Proven experience designing and evolving component libraries, design systems, service architectures, and API boundaries Fluency with gRPC, RESTful, and WebSocket-based services, including designing APIs that serve both frontend and backend needs effectively
• Strong database experience with PostgreSQL, including schema design, query optimization, and understanding of data modeling tradeoffs
• Track record of working in Git-based workflows with high standards for commit hygiene, PR quality, and collaborative review processes
• U.S. Citizen and eligible for DoD Secret or TS/SCI clearance
Preferred:
• Bachelor’s degree in computer science or similar discipline
• Experience as a technical lead or primary implementor on a product with real users and production constraints, with responsibility spanning both frontend and backend
• Experience building and shipping complex, data-dense applications with demanding performance requirements (large datasets, real-time updates, complex visualizations) across the full stack
• Deep experience with Three.js, React Three Fiber, or other web-based 3D libraries, including performance profiling and optimization
• Deep understanding of OTP including BEAM scheduling, GenServers, run queues, pg, the Actor model, and advanced patterns like dynamic supervisors, registries, and distributed process groups
• Experience with monitoring, observability, and distributed tracing in production systems (e.g., OpenTelemetry, Prometheus, Grafana)
• Experience in UI/UX design collaboration and tools like Figma, able to speak the language of design and advocate for engineering constraints
• Strong collaboration and communication skills that let you thrive in a culture that values respectful, professional, and constructive conflict
