Company: Dex
Apply for the Platform/Product Engineer (up to £150k)
Location: London
Job Description:

The role

This company builds the logistics middle‑layer for armed forces. They track inventory, flag supply gaps, and optimise tactical supply routes under extreme constraints. Their software collapses an 84‑hour ammunition‑order cycle into the 16‑hour window where battles are decided. This isn’t about incremental gains; it’s about a 90% reduction in compute time versus current methods. They’re backed by leading investors, with a small team of six bringing deep experience from top tech and military backgrounds.

You will own the backend infrastructure that makes this possible, including data processing, network optimisations under battlefield conditions, and classical ML pipelines. This is not a deep‑learning role but focuses on robust, signal‑pipeline‑shaped traditional ML running on constrained, battle‑proven hardware. You will join a small, high‑ownership team with significant autonomy.

The work

  • Design and build the core backend infrastructure for a logistics platform operating in extreme, constrained environments.
  • Develop and optimise classical ML pipelines, transforming intelligence feeds (drone observations, C2 inputs) into critical supply-routing decisions.
  • Engineer for on‑prem deployment on hardware with strict compute and memory limits (e.g., 16–20 CPUs, 64GB RAM per server).
  • Integrate with complex, legacy command‑and‑control systems, ensuring robust data flow and interoperability.
  • Own end-to-end system design from ambiguous requirements, delivering battle-ready software where reliability is paramount.

What You Bring

  • 2–5 years building production software, with a strong background in platform or infrastructure engineering.
  • Experience with, or a strong desire to focus on, classical ML and signal‑processing pipelines, rather than deep learning.
  • Proven ability to thrive in ambiguity, balancing technical depth with business context in a high‑ownership environment.
  • Background in defence (primes or start‑ups), finance/hedge funds (signal pipelines), or roles requiring security clearance.
  • Hold NATO citizenship (hard requirement).
