About the role

Epsilon3 is the OS for spacecraft and complex operations. We are an experienced team of engineering and design leaders from SpaceX, Google, Northrop, and Stanford. Our team worked firsthand on over 100 launches, including training and coordinating operations for multiple astronauts who successfully traveled to space and back. Epsilon3 is the result of decades of learning and delivers on the promise of making testing and operations as efficient, error-free, and enjoyable as possible. We are backed by Y Combinator and other world-class investors.

We are looking for site reliability engineers to join our team who are passionate about space and building scalable, reliable, and secure software. You will be responsible for building and supporting complex infrastructure and deployment scenarios. We are currently using technologies such as React, CouchDB, AWS GovCloud, and TypeScript, and we expect our stack will evolve rapidly over time as we hone our solutions and approach.

This is an exciting role in a fast-growing company. The ideal candidate is someone who has experience building scalable and robust distributed systems from design to production and deployment.

Some of 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 simplicity and delightfulness of user experience

Responsibilities:

  • Support and contribute to the entire lifecycle of our software, from inception and design, through to deployment, operation and refinement
  • Support our services in production and before they go live through system design, security considerations, capacity planning, and launch preparedness
  • Build processes and systems to continuously improve system reliability and performance
  • Build processes and systems to continuously improve the productivity of the rest of the development team
  • Scale systems sustainably through automation and continuous improvement in reliability and velocity
  • Practice sustainable incident response and postmortems
  • Contribute to the design, build, test, and release of our web-based operational dashboards, electronic procedure tools, and suite of specialized software solutions to support various missions
  • Join and actively participate in customer discovery calls and technical demonstrations
  • Analyze and enhance the security, efficiency, stability, and scalability of our software systems
  • Support software QA and user testing
  • Support and facilitate security reviews and audits of our systems by customers and third parties
  • Facilitate compliance with cybersecurity certifications and contribute to improvements in our security policies and processes
  • Assess third-party and open source software and develop integrations
  • Contribute to the growth and refinement of our engineering culture, processes, and tools

Qualifications:

  • Bachelor’s Degree in Computer Science or related field
  • 5+ years of experience in production software engineering
  • Proficiency in Python, JavaScript, and C++/Java/Go/Rust
  • 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)
  • US Citizenship and/or Permanent Residency (future security clearance may be required)
  • Experience in fast-growing tech startups is a plus
  • Experience with Lean Startup methodologies (agile software development and customer development) is a plus

About the interview

The interview process starts off with a 45 minute, 1:1, technical interview with an engineer on our team. You’ll run through some coding exercises and CS fundamentals, learn more about the product and current tools used, plus get a quick overview of the day-to-day at Epsilon3. The second step will be additional 45 minute, 1:1 interviews with our co-founders and additional members of our engineering team. These interviews will focus on culture fit as well as technical skills. We like to keep our process short and sweet as we know time is very valuable. After the second interview, we're at the offer stage!
