Staff Software Engineer, Full Stack

Responsibilities

• Lead and deliver large-scale, cross-functional initiatives that span the entire stack, aligning frontend experience, backend infrastructure, and system architecture with strategic company objectives, from technical vision through production deployment and long-term evolution
• Define and drive the full-stack technical roadmap and architectural strategy, establishing patterns, frameworks, and systems that enable the entire engineering organization to move faster across both React/TypeScript and Elixir codebases
• Serve as the primary technical decision-maker for cross-stack architecture, evaluating and adopting new technologies, defining the boundaries and contracts between frontend and backend systems, and establishing engineering standards that balance innovation with maintainability
• Proactively identify systemic technical debt, scalability challenges, and architectural limitations across the stack, then build business cases, secure buy-in, and lead multi-quarter initiatives to address them
• Elevate the engineering organization through technical mentorship, establishing best practices, leading design reviews, and developing the skills of senior, mid-level, and junior engineers across both frontend and backend disciplines
• Partner with executive leadership, product, design, space operations, and astrodynamics teams as a key technical stakeholder, influencing product strategy and company direction with a perspective that encompasses the entire technical surface
• Drive engineering efficiency and excellence by establishing metrics, tooling, and processes that improve code quality, system reliability, deployment velocity, and developer experience across the stack
• Build and maintain technical documentation, architectural decision records, and knowledge-sharing systems that scale organizational learning
• Represent the full-stack engineering perspective in strategic planning, resource allocation, and cross-company technical decisions
• Identify and develop emerging technical leaders within the team, creating growth pathways and opportunities for engineers to expand their impact across the stack
