Wanna join the adventure?

Loft Orbital flies other people's payloads and software on standardized satellites, and we are building the first marketplace for space-based AI applications: the store where partners publish, deploy, and monetize AI solutions that run on satellites in orbit. We are hiring the founding developer of that marketplace. You will work directly with the Director of Marketplace to take the platform from MVP to the system behind dozens of partner solutions, on a small team where you own features end-to-end and ship weekly.

Build the Marketplace storefront, partner portal, and admin tooling.
Design and implement the APIs and services behind them: catalog, onboarding, entitlements, and metering.
Integrate with our mission platform for authentication, workflow triggers, and solution deployment in close collaboration with engineering teams.
Build connectors for third-party constellations and data providers.
Own quality: tests, CI/CD, monitoring.

4+ years building and shipping full-stack products.
Experience with Sprint development.
Strong TypeScript/React on the front end and solid backend experience in Python, Go, or Node.
Cloud-native by default (we run on GCP): containers/kubernetes, managed services, infrastructure as code.
Comfortable with API design, OAuth, and multi-tenant authorization.
Fluent with AI-assisted development workflows and expected to use them.
You have shipped a zero-to-one product, ideally a marketplace, developer platform, or SaaS portal, and you like small teams with large scope.

Billing integrations (Stripe or similar).
Geospatial or earth observation exposure.
Security-minded engineering (tenant isolation, audit trails).
Experience in the architecture of modern systems.

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)

Cross-office travel opportunities between San Francisco, Colorado, and Toulouse to learn from our differences

Company and team off-sites and many other events to work & celebrate together

Relocation assistance to Toulouse when applicable

*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 simple 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, on-orbit AI, 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 30 missions flown, Loft’s flight heritage and proven technologies enable customers to focus on their mission objectives.

With a growing fleet on track to reach 30 satellites by 2027, we are scaling up quickly across our offices in San Francisco, CA | Golden, CO | and Toulouse, France to meet accelerating demand for space infrastructure.

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