Job Description

Job Description

Epsilon3 is a multi-product operations management platform revolutionizing the way teams build, launch, and operate spacecraft and other advanced hardware systems.

Launched in 2021, our company is led by engineers from SpaceX, Google, and NASA, who have experience supporting over 100 space missions. Innovative teams at Blue Origin, Rocket Lab, Axiom Space, Firefly Aerospace, and many others depend on our web-based (SaaS) solutions to plan and track high-stakes procedures. We raised a $15M Series A funding round led by Lux Capital, Y Combinator (YC S21), and other world-class investors.

We're looking for Software Engineers who are interested in space exploration and passionate about building scalable, reliable software. You will be responsible for creating delightful user experiences that solve very complex problems. We are currently using technologies such as Node.js, React, Llama, Postgres, AWS GovCloud, Docker, and Kubernetes, and we expect our stack to evolve over time as we scale our solutions and approach.

This is an impactful role within a fast-paced startup. The ideal candidate is someone who has experience designing and implementing software systems from requirements to production and deployment.

The Technical Challenges We’re Undertaking
  • Real-time synchronization of data and user interfaces across Earth and space
  • Visualization of many complex data fields
  • Integration of multiple high-bandwidth data streams for real-time processing and display
  • Multiple deployment environments, including cloud and on-premises
  • Mission-critical security and reliability requirements
  • Supporting complex workflows and detailed tracking while also maintaining intuitive and delightful user experiences
  • Impactful AI/ML features that boost team efficiency and enable fast, data-driven decisions
Responsibilities
  • Design, build, test, and release our web-based operational dashboards, electronic procedure tools, and a suite of specialized software solutions to support various space missions
  • Create software to support simple and complex computation on datasets for decision-making and autonomous execution
  • Build and deploy high-quality code on a daily basis for rapid iteration and testing with users
  • Design APIs and integration solutions for various proprietary and open-source telemetry and command and control systems
  • Rapidly prototype demos and proof-of-concepts for customer meetings
  • Join and actively participate in customer discovery calls and technical demonstrations
  • Analyze and enhance the efficiency, stability, and scalability of software systems
  • Support software QA and user testing
  • Assess third-party and open-source software and develop integrations
  • Contribute to the growth and refinement of our engineering culture, processes, and tools
Qualifications
  • 3+ years of experience as a Software Engineer
  • Proficiency with TypeScript and with JavaScript frameworks like React, Vue, Angular, or Svelte
  • Strong foundation in computer science concepts (algorithms, data structures, object-oriented programming, design, testing, etc.)
  • Self-starter and able to navigate ambiguity and assess rapidly evolving priorities
  • Strong team player with great communication skills and collaborative work ethic
  • Love of learning (technical and otherwise)
  • Experience at fast-growing tech startups is a plus
  • Experience with Lean Startup & Agile software development methodologies is a plus
  • Bachelor’s Degree in Computer Science or related field
  • US Citizenship required (future security clearance may be required)
  • Must be located in the United States
