Technical Operations Engineer — Defence & Mission Systems | London
Hybrid/Field-based | Up to 50% travel
We're working with a fast-scaling, VC-backed defense technology company building next-generation sensing and detection systems that protect critical infrastructure and military operations worldwide. Having recently opened their London office, they're now hiring a small team of Technical Operations Engineers to be the boots-on-the-ground link between cutting-edge hardware/software and the customers who depend on it in the field.
The Role
You'll sit at the intersection of hardware and software — integrating sensors, RF devices, and mission-critical software into customer environments, diagnosing complex issues that span networking, hardware, and code, and building the tools and automation that keep systems reliable under real-world conditions. This isn't a desk job: you'll be embedded on customer sites roughly half your time, solving problems live rather than from a support ticket queue.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What you'll be doing
- Integrating sensor and RF systems with customer infrastructure — physically (networking, power, hardware bring-up) and via software (APIs, data pipelines)
- Debugging complex issues spanning hardware, software, and networking layers
- Developing scripts, diagnostics, and automation to improve system reliability
- Feeding operational insight back to engineering to directly shape product improvements
- Documenting configurations, fixes, and lessons learned for internal and customer use
- Traveling to customer and test sites for deployment, troubleshooting, and mission support
What we're looking for
- Strong technical foundation — degree in Engineering, Computer Science, Physics, or equivalent hands-on experience
- Deep comfort in Linux environments — SSH, networking tools, system-level debugging
- Proficiency in Python, Bash, or similar scripting/programming
- Experience integrating or maintaining hardware or sensor systems
- A problem-solver who can operate independently and under pressure, in the field
- Genuine enthusiasm for travel and on-site technical work

Nice to have
- Background in defense, aerospace, or other mission-critical environments
- Experience with telemetry, IoT-style architectures, or distributed systems
- Exposure to cloud/edge environments (Docker, AWS, Azure)
- Strong documentation and communication skills — comfortable bridging technical and customer-facing conversations
This is a rare opportunity to join a team early, with genuine scope to grow into a technical lead or mentoring position as the London team scales. If you've spent time solving hard problems in demanding, real-world environments — whether that's a military, aerospace, or complex commercial field engineering background — we want to hear from you.
