Open Cosmos Systems Engineer interview questions & guide 2026

The following questions represent the patterns observed in Open Cosmos interviews. While specific technical challenges may vary based on your specialization, the focus remains on your ability to apply engineering principles to space-sector problems and your alignment with our mission.

Industry Knowledge & Vision

These questions test your understanding of the current space landscape and the specific value proposition of LEO satellite applications.

• How do you perceive the current growth of the LEO satellite market?
• What, in your view, are the primary challenges of operating small satellites in LEO?

Preparation for Open Cosmos requires a balance between deep technical expertise and the ability to articulate the "why" behind your engineering choices. You should be ready to demonstrate not just your ability to solve a problem, but how you document and communicate your process.

Role-related Knowledge – You must be fluent in the specific domain of your application, whether that is thermal, AOCS, or spectrum engineering. Interviewers look for evidence that you understand the constraints of the space environment and the specific hardware we deploy.

Analytical Thinking – We look for candidates who can break down ambiguous problems into manageable, logical steps. Be prepared to talk through your thought process out loud, as interviewers are more interested in your methodology than in finding a perfect, memorized answer.

Communication & Alignment – Because we work in highly collaborative teams, your ability to explain complex trade-offs is essential. Show that you understand our business model and how your technical output contributes to our overarching goal of making space accessible.

The interview process at Open Cosmos is designed to be professional, transparent, and focused on both your technical baseline and your cultural fit. You can expect an initial screening that prioritizes your motivation for joining the space sector and your ability to articulate the industry's challenges. Following this, the process moves into more technical evaluations where your specific domain knowledge—such as AOCS, thermal, or spectrum analysis—is assessed through practical, scenario-based discussions.

The pace is generally efficient, with a focus on assessing your potential to grow within our engineering teams. We value candidates who demonstrate a structured approach to problem-solving and who ask insightful questions about our satellite platforms and mission objectives.

This timeline illustrates the progression from initial behavioral screens to technical deep-dives. Use this to structure your preparation, ensuring you have a strong narrative for your experience in the early stages and a solid grasp of your technical fundamentals for the later, more rigorous discussions.

Technical Competency

We evaluate your depth in your specific field. For a Systems Engineer, this means understanding how your subsystem interacts with the rest of the satellite bus. Strong performance is characterized by an ability to navigate trade-offs between competing requirements like power consumption versus thermal dissipation.

Be ready to go over:

• System Constraints – Understanding mass, power, and volume limits.
• Orbital Mechanics – Basic knowledge of how orbits affect system requirements.

As a Systems Engineer, your day-to-day work involves more than just design; it involves integration and coordination. You will be expected to define system requirements, manage interface control documents, and participate in design reviews. You will work closely with other engineering leads to ensure that the thermal, electrical, and mechanical subsystems function as a cohesive unit.

Beyond design, you will contribute to the verification phase, ensuring that our hardware survives the launch and thrives in orbit. You will often act as a focal point for cross-functional teams, ensuring that product requirements are clearly communicated and that any technical deviations are addressed with a systemic view of the mission.

A strong candidate for this role possesses a blend of high-level systems thinking and hands-on engineering experience.

• Must-have skills:
  • Degree in Aerospace Engineering, Physics, or a related field.
  • Demonstrated experience in a space-related engineering role (e.g., AOCS, Thermal, or Spectrum).
  • Proficiency in technical documentation and requirement management.
• Nice-to-have skills:
  • Experience with LEO satellite missions or small-sat platforms.
  • Familiarity with industry-standard modeling and simulation software.
  • Ability to navigate international regulatory environments for spectrum or space operations.

Q: How long does the interview process typically take? The process is generally efficient, typically spanning a few weeks from the initial screen to a final decision. We aim to keep communication lines open throughout your journey.

Q: Should I focus more on behavioral or technical questions? You should be prepared for both equally. The initial stages are heavier on behavioral and industry-interest questions, while later stages require a solid grasp of your technical domain.

Q: Is there a specific focus on "culture fit"? Yes, we look for individuals who are passionate about the democratization of space and who work well in highly collaborative, fast-moving teams where ambiguity is common.

Q: Are there remote work options? Most roles, especially those requiring close integration with hardware, are based at our primary locations in the UK. Please clarify location expectations for your specific role during the initial screening.

• Understand the Mission: Spend time on our website understanding our satellite-as-a-service model. Being able to explain why Open Cosmos is a market leader will set you apart.
• Think Systemically: Even if you are interviewing for a specialized role like Thermal, always consider how your decisions affect the AOCS or Power systems.
• Prepare Your "Why": Be ready to explain why you want to move into the space sector and why you chose Open Cosmos specifically.
• Ask Insightful Questions: Use the interview to ask about our development cycle or how we handle mission-critical failures. It demonstrates deep interest and maturity.

The Systems Engineer role at Open Cosmos is a challenging, high-impact position that allows you to shape the future of space infrastructure. By focusing on your core engineering fundamentals, demonstrating a clear understanding of LEO satellite constraints, and showing a genuine passion for our mission, you will be well-positioned to succeed. Remember that your ability to think critically about system-level trade-offs is just as important as your technical proficiency.
