Job description

Aim high, go beyond!

At Open Cosmos we are solving the world’s biggest challenges from space, providing businesses, governments and researchers access to more readily available information than ever before - ready for the challenge? Then read on…

About the team

You’ll be joining our Dependability & Thermal Team, part of the wider Systems Team at Open Cosmos.

Our Systems Team brings together experts across systems, AOCS, and thermal engineering to design, integrate, and optimise every element of our satellites—from overall architecture down to the detail of each subsystem. They own the journey from early concept through to launch and operations, making sure everything fits, works, and performs in orbit.

Within this, the Dependability & Thermal Team is responsible for ensuring our systems are reliable, resilient, and built to last. We lead on reliability engineering, radiation assessment, and thermal analysis, as well as the tools and processes that underpin them. Our goal is simple: to make sure every system and subsystem is designed, validated, and operated to deliver consistent performance throughout the mission lifecycle.

What You’ll Be Doing

In this role you’ll play a role in leading RAMS activities across programmes, shaping how we design for reliability and resilience while influencing system architecture and key engineering decisions.

This includes:

• Leading RAMS strategy across missions, ensuring our systems are designed for reliability from day one
• Owning reliability engineering across programmes, from concept through to in‑orbit operations
• Defining how we approach radiation, fault tolerance, and system resilience at an architectural level
• Driving FMEA and FDIR approaches across the organisation, ensuring consistency and quality
• Acting as a key voice in design reviews, influencing decisions that balance performance, risk, and cost
• Working directly with customers, partners, and suppliers on mission‑critical topics
• Identifying risks early and shaping solutions at system and programme level
• Continuously improving how we do RAMS; tools, processes, and standards
• Supporting and mentoring other engineers, helping build capability across the team

What You’ll Bring

• Deep technical understanding of reliability, systems, or electronics engineering
• The ability to lead complex work and influence decisions across teams
• Strong systems thinking, you see how everything connects and where risks sit
• Confidence operating in ambiguity and making sound engineering judgments
• The ability to communicate clearly and influence both technical and non‑technical stakeholders
• Strong analytical capability, backed by a structured and pragmatic approach
• Familiarity with RAMS tools, methods, and standards, or equivalent experience in high‑reliability environments
• A mindset focused on improving systems, processes, and outcomes—not just delivering tasks
