Senior Software Engineer, Front End

Senior Front End Software Engineer We are seeking a dedicated Senior Front End Software Engineer to contribute to the continuous evolution of our complex spacecraft modeling and simulation software. Responsibilities Own and deliver complex 2D and 3D web‑based front‑end features end‑to‑end, from technical design through production deployment and iteration. Drive architectural direction for front‑end systems, establishing patterns and conventions that scale across the team and codebase. Proactively identify and address technical debt, performance bottlenecks, and opportunities for refactoring. Set the quality bar through rigorous code review, champion testing practices, and write 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. Collaborate as a technical partner with product, design, backend engineers, QA, space operators, and astrodynamics algorithm engineers—contributing to system‑wide architectural decisions. Ship efficiently and iteratively, breaking complex 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. What Success Looks Like in This Role When a junior engineer’s pull request violates codebase conventions, you take the time to explain the patterns and why they matter. When a component is copy‑pasted across the codebase, you propose and implement an abstraction, then document when and how to use it. When assigned a feature with ambiguous requirements, you proactively clarify with product and design, propose a technical approach, and share it with the team before diving into implementation. You see downtime as an opportunity, not a break—capturing flaky tests and fixing them proactively. You constructively challenge an architectural decision, propose alternatives with trade‑offs, and commit fully once a decision is made. You think beyond your current ticket, aware of how your work fits into the broader product roadmap and technical direction, and surface risks or opportunities early. Qualifications 7+ years of software development experience. Deep expertise in modern React, including advanced patterns (compound components, render props, custom hooks), state management strategies, and performance optimization techniques. Strong testing philosophy and hands‑on experience with Vitest, React Testing Library, and end‑to‑end testing frameworks; you understand what to test, not just how to test. Proven experience designing and evolving component libraries, design systems, and CSS architecture at scale. Fluency with gRPC, RESTful and WebSocket‑based services, including debugging integration issues and contributing to API design discussions. Comfort operating across the stack when needed, able to read backend code, understand infrastructure constraints, and collaborate effectively with backend engineers. 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 Skills and Experience Strong engineering background in software engineering, math, physics, or related fields. Experience as a technical lead or primary front‑end architect on a product with real users and production constraints. Experience building and shipping complex, data‑dense applications with demanding performance requirements (large datasets, real‑time updates, complex visualizations). Deep experience with Three.js, React Three Fiber, or other web‑based 3D libraries, including performance profiling and optimization. Experience collaborating with UI/UX designers and using tools like Figma; you can advocate for engineering constraints. Practical space‑industry experience. Strong collaboration and communication skills. Compensation Equity + Benefits including health, dental, vision, HRA/HSA options, PTO and paid holidays, 401(k), and parental leave. Additional Requirements Fully onsite role: candidates must be based in or able to commute to our Denver or Long Beach office daily.
