Wanna join the adventure?

If you’re looking for a role that combines backend development, satellites, and space infrastructure, you’ve knocked on the right door.

We are looking for a talented Backend Engineer to join our Software team and help build the foundation of our space infrastructure. You’ll develop systems that automate and streamline hardware and software integration testing, mission operations, and ensure our satellites are always ready to fly. Your work will be critical to scaling our platform and making space more accessible for our customers.

About this Role:

• Collaborate with the Product Engineering, Flight Systems, Space Operations, and AIT teams to design features that automate hardware testing and software integration.
• Build systems to validate mission requirements and ensure full coverage with a “test as you fly” approach.
• Work on both in-orbit missions and upcoming launches — helping solve real-time issues and supporting operational success.
• Contribute to building modern, automated space infrastructure where software plays a central role.
• Help abstract the complexity of space operations and accelerate our customers’ journey to orbit.

Must Haves:

• Strong experience with object-oriented languages, ideally Python.
• Proficiency with Docker and container-based development
• Knowledge of API design best practices
• Familiarity with version control (Git) and CI tools (GitLab CI, Jenkins, Travis CI, etc.)
• Experience with backend web development frameworks
• A curious mindset and a natural problem-solver

Nice to Haves:

• Experience with GraphQL.
• Practical experience with Kubernetes.
• Exposure to scaling mission-critical, distributed or real-time systems.
• Interest in the space industry and operations.

Some of Our Awesome Benefits:

• Equity, we want you to have an active role in our success
• Up to 35 days of Paid Time Off (vacations & RTT ) and flexible working hours, we want you to be at your best
• Health and life insurance, we care about your health
• Lunch Vouchers, because let’s be honest, we love food! (we even have a slack channel about it #loft-gourmand)

***Research shows that while men apply to jobs where they meet an average of 60% of the criteria, women and other underrepresented people tend to only apply when they meet 100% of the qualifications. At Loft, we value respectful debate and people who aren’t afraid to challenge assumptions.  We strongly encourage you to apply, even if you don’t check all the boxes.

Who We Are

Loft: Space Made Simple. 

Founded in 2017, Loft provides governments, companies, and research institutions with a fast, reliable, and flexible way to deploy missions in orbit. 

We integrate, launch, and operate spacecraft, offering end-to-end missions as a service across Earth observation, IoT connectivity, in-orbit demonstrations, national security missions, and more. Leveraging our existing space infrastructure and an extensive inventory of satellite buses, Loft is reducing years-long integration and launch timelines to months. With more than 25 missions flown, Loft’s flight heritage and proven technologies enable customers to focus on their mission objectives. 

At Loft, you’ll be given the autonomy and ownership to solve significant challenges, but with a close-knit and supportive team at your back. We believe that diversity and community are the foundation of an open culture. We are committed to hiring the best people regardless of background and make their time at Loft the most fulfilling period of their career.

We value kind, supportive and team-oriented collaborators. It is also crucial for us that you are a problem solver and a great communicator. As our team is international, you will need strong English skills to better collaborate, easily communicate complex ideas and convey important messages.

With 4 satellites on-orbit and a wave of exciting missions launching soon, we are scaling up quickly across our offices in San Francisco, CA | Golden, CO | and Toulouse, France.

As an international company your resume will be reviewed by people across our offices so please attach a copy in English.
