Senior Software Engineer, Full Stack

Space is a warfighting domain. True Anomaly seeks those with the talent and ambition to build the technology that secures it.OUR MISSIONTrue Anomaly delivers decisive capabilities for space superiority. We build autonomous spacecraft, advanced payloads, mission software, and space-based interceptors — enabling the U.S. and its Allies to secure the space environment and counter threats from the ultimate high ground.OUR VALUESBe the offset. We create asymmetric advantages with creativity and ingenuity.What would it take? We challenge assumptions to deliver ambitious results.It’s the people. Our team is our competitive advantage and we are better together.YOUR MISSIONSoftware is the central nervous system for True Anomaly's engineering and product thesis. Software bridges the gap between military objectives, theoretical astrodynamics and the human and autonomous control of spacecraft and ground systems in time and space. True Anomaly is seeking a dedicated Senior Full Stack Software Engineer to drive feature development and architectural decisions across our React/TypeScript frontend and Elixir backend, shaping the evolution of our spacecraft modeling, simulation, and ground control software.This is a high-autonomy, high-accountability role. You'll own entire feature domains from conception to production across the full stack, drive architectural decisions that affect both the frontend experience and backend infrastructure, and set the standard for code quality that junior and mid-level engineers will follow. You won't wait to be assigned work; you'll identify what needs to be done, propose solutions, and drive them to completion. When you see tech debt on either side of the stack, you'll flag it, scope it, and champion the work to address it. When patterns aren't serving us, you'll propose better ones and lead their adoption.You do not need to have experience building space ground systems or experience in aerospace. You'll have ownership of challenging, greenfield problems and a chance to fundamentally impact the outcome of future conflict (and the future of the company), all while enjoying world-class benefits including platinum healthcare, flexible work hours/location, highly competitive compensation and a generous stock options package.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 iterationDrive 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 layersProactively identify and address technical debt, performance bottlenecks, and reliability risks across the stackSet 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 teamMentor 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 inCollaborate 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 stackShip efficiently and iteratively, breaking complex cross-stack work into well-scoped increments while maintaining a bias toward completion over perfectionDocument decisions and patterns, ensuring the team's collective knowledge grows and onboarding becomes easier over time WHAT SUCCESS LOOKS LIKE IN THIS ROLE You see a PR from a junior engineer that implements a feature on the frontend but introduces an inefficient API call pattern; you don't just fix the frontend; you suggest a backend change that solves the problem at its root and explain the tradeoffsYou notice the same data transformation happening in both the Elixir backend and the React frontend; you determine the right layer for it, consolidate, and document the decision for the teamYou're assigned a feature and the requirements are ambiguous; you proactively clarify with product and design, propose a technical approach that accounts for both frontend UX and backend system design, and share it with the team before diving into implementationYou see downtime as an opportunity, not a break; you're the kind of engineer who notices a flaky integration between the frontend and a WebSocket endpoint and decides to finally fix both sidesYou disagree with an architectural decision; you articulate your concerns constructively, propose alternatives with tradeoffs, and commit fully once a decision is madeYou're thinking beyond your current ticket; you understand how frontend features depend on backend services and vice versa, and you surface risks, coupling issues, or opportunities early QUALIFICATIONS 7+ years of software development experience with meaningful depth across both frontend and backend developmentExpert-level command of HTML/CSS and modern TypeScript/JavaScript, including nuanced understanding of performance implications and browser internalsDeep expertise in modern React, including advanced patterns (compound components, render props, custom hooks architecture), state management strategies, and performance optimization techniquesStrong proficiency in Elixir and OTP, including deep understanding of BEAM internals, process architecture, supervision strategies, and fault-tolerant system designStrong 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 howProven 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 effectivelyStrong database experience with PostgreSQL, including schema design, query optimization, and understanding of data modeling tradeoffsTrack record of working in Git-based workflows with high standards for commit hygiene, PR quality, and collaborative review processesU.S. Citizen and eligible for DoD Secret or TS/SCI clearancePREFERRED SKILLS AND EXPERIENCE Bachelor’s degree in computer science or similar disciplineExperience as a technical lead or primary implementor on a product with real users and production constraints, with responsibility spanning both frontend and backendExperience building and shipping complex, data-dense applications with demanding performance requirements (large datasets, real-time updates, complex visualizations) across the full stackDeep experience with Three.js, React Three Fiber, or other web-based 3D libraries, including performance profiling and optimizationDeep understanding of OTP including BEAM scheduling, GenServers, run queues, pg, the Actor model, and advanced patterns like dynamic supervisors, registries, and distributed process groupsExperience 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 constraintsStrong collaboration and communication skills that let you thrive in a culture that values respectful, professional, and constructive conflictCOMPENSATIONBase Salary: $180,000 - $265,000Equity + Benefits including Health, Dental, Vision, HRA/HSA options, PTO and paid holidays, 401K, Parental Leave Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, location, and experience.
