About ODES
ODES is building uncompromising tools for NewSpace. These are already possible to build with today’s technology and a few simplifications — so we’re building a small team of exceptional, hands-on engineers and scientists to make it happen.
The NewSpace race is real and exciting. From revolutionary research to day-to-day applications that help save lives and our very planet, space technology is already shaping our reality. The promise is vast and greatly unexplored. But our tools do not live up to that promise. Mission failure rates are far too high, while time-to-launch and engineering cost can be drastically cut down. We’re confident our team can tackle any challenge and are set to bring tried-and-true technologies to NewSpace.
About the team
ODES is one small team building one big thing: a web app that aerospace engineers use to design, validate, and operate spacecraft, from early mission analysis through in-orbit operations. Our software engineers build the product across frontend, backend, data, and simulation; our scientists ground it in real spacecraft physics and validation methodology; and our business team carries the work outward—telling the story, building the pipeline, and turning hard engineering into missions that actually fly.
Everyone here builds the same thing, just from a different seat—software, science, and business all shape the roadmap, the next customer, and the next module. When a mission validated on ODES reaches orbit and survives, that’s a win we all own, and you’ll help build it.
About the role
We’re looking for a spacecraft simulation engineer who turns physics into working, validated software. You’ll build and validate the functional models at the heart of the platform, translating a defined scientific architecture into tested simulation code. It’s a hands-on role on a small team, where you go deep on real spacecraft problems and own meaningful work from early on.
You’ll work across spacecraft subsystems and watch a model travel the whole way from design through optimization to operations, as the platform matures from a simulation engine into a full design framework — a rare, end-to-end view almost no role offers.
The ideal candidate reasons from first principles and trusts physics over intuition — when a result looks off, they chase down why rather than take it on faith. They’re comfortable writing scientific code, move fast between hypothesis and validation, and care that a model holds up against real flight data, not just that it runs.
Responsibilities
- Turn the physics of spacecraft subsystems into working simulation models, to a defined scientific architecture.
- Validate model outputs against real mission and reference data, and chase down discrepancies.
- Run simulations, analyze results, and turn them into clear findings.
- Help build the trade-study and design-optimization layer as the platform grows from a simulation engine into a design framework.
- Document what you build so it holds up as we mature.
Required experience
- A degree in aerospace, physics, ECE, or an adjacent field — we care more about how you reason than your exact credential or years.
- Strong grounding in physics, able to reason from first principles about an unfamiliar subsystem and to question whether a result makes physical sense rather than take it on faith.
- Comfortable writing scientific code, with solid Python or MATLAB and the drive to pick up Julia fast.
- A project or thesis you can walk us through in depth.
Nice-to-haves
- Hands-on experience with spacecraft subsystems — orbital mechanics, attitude dynamics (GNC/AOCS), or antenna and RF/comms systems.
- Familiarity with Julia and its scientific-computing ecosystem.
- Experience validating simulation models against real flight telemetry or reference data.
- Exposure to CubeSat or small-satellite missions, hardware, or operations.
Working at ODES
We’re an early-stage deep-tech startup with solid funding and great advisors. We work fully remotely, with a lab in Athens, GR always open for anyone who needs a dedicated space.
Compensation: ODES is committed to fair and equitable compensation practices. Compensation is determined based on your qualifications and experience. Our total compensation package also includes generous equity in ODES.
We are an equal-opportunity employer and do not discriminate on the basis of race, religion, national origin, gender, sexual orientation, age, veteran status, disability or other legally protected statuses.
Interview process
You’ll have a discussion with our CSO about something you built and what we’re set out to achieve. The second stage is a discussion with all three founders — for both us and you to see if we’re a great fit for one another. After that, we’ll go hang and have a good laugh!
