How to Apply for Flight Software Product Assurance Engineer
at constellr
🏢 About constellr
constellr is a pioneering Earth observation startup dedicated to revolutionizing climate monitoring by tracking land surface temperatures from space. Their focus on high-frequency thermal infrared data offers a unique opportunity to work on cutting-edge technology with direct impact on climate action and agriculture, all while enjoying the flexibility of a remote-first culture based in Germany.
About This Role
As a Flight Software Product Assurance Engineer, you will be instrumental in ensuring the reliability and safety of the flight and ground software across constellr's satellite constellation. Your work directly supports the mission's success by defining testing strategies, managing software anomalies, and ensuring compliance with rigorous space industry standards like ECSS.
💡 A Day in the Life
A typical day might start with a stand-up meeting with the software and systems teams to discuss ongoing verification activities and any anomalies. You'll then dive into reviewing a supplier's software delivery documentation for ECSS compliance, followed by updating the product assurance plan or coordinating a test campaign for an upcoming satellite integration milestone.
🚀 Application Tools
🎯 Who constellr Is Looking For
- Has proven experience in Flight Software Product Assurance within the space industry, including hands-on work with ECSS standards (Q-ST-80C, E-ST-40C).
- Possesses strong understanding of embedded flight software for satellites, spacecraft platforms, or payload systems, with familiarity in FDIR concepts.
- Is skilled in software testing, verification, and validation in safety-critical environments, and can develop robust configuration management and release processes.
- Thrives in a startup environment, comfortable with remote collaboration, and proactive in improving processes and managing supplier deliveries.
📝 Tips for Applying to constellr
Tailor your CV to highlight specific ECSS standards experience, especially Q-ST-80C and E-ST-40C, with examples of how you applied them in past projects.
Mention any experience with FDIR (Fault Detection, Isolation, and Recovery) explicitly, as it is highly desirable for this role.
Showcase your ability to work remotely and independently by providing examples of successful remote collaboration or self-managed project milestones.
Include a brief paragraph in your cover letter explaining why climate monitoring and constellr's mission specifically excite you, not just space in general.
If you have experience with supplier management in the space industry, highlight it as a key differentiator for this role.
✉️ What to Emphasize in Your Cover Letter
['Emphasize your direct experience with ECSS standards and how you have ensured compliance in previous flight software projects.', 'Highlight your expertise in software verification and validation strategies, especially in safety-critical satellite systems.', 'Demonstrate your ability to manage anomalies and coordinate with suppliers, showing you can handle the full product assurance lifecycle.', "Express genuine interest in climate monitoring and constellr's mission to track land surface temperatures, connecting your work to broader environmental impact."]
Generate Cover Letter →🔍 Research Before Applying
To stand out, make sure you've researched:
- → Study constellr's technology: understand their thermal infrared sensors and how they measure land surface temperature from space.
- → Read about their constellation architecture: how many satellites, orbits, and planned data products.
- → Familiarize yourself with the ECSS standards mentioned in the job description: Q-ST-80C (software product assurance) and E-ST-40C (software engineering).
- → Look into constellr's recent news or funding rounds to understand their growth stage and team culture.
💬 Prepare for These Interview Topics
Based on this role, you may be asked about:
⚠️ Common Mistakes to Avoid
- Don't overlook the remote aspect: failing to demonstrate self-discipline or remote work experience can be a red flag.
- Avoid generic statements about space passion without connecting to constellr's specific climate mission.
- Don't neglect to mention ECSS standards explicitly; many applicants may have software assurance experience but not in the space context.
