Senior Software Engineer (Space)

C++ Software Engineer – High-Performance Systems

The Company

We’re partnering with a cutting‑edge engineering‑led company building advanced platforms for complex, real‑world environments across space and defense.

Their work sits at the intersection of high‑performance computing, signal processing, and scalable software systems, with a strong emphasis on speed, reliability, and real‑world deployment.

The Role

This is a hands‑on

C++ Software Engineering

role focused on building and optimising high‑performance systems.

You’ll take ownership of core software components, working on performance‑critical code and helping evolve systems from flexible Python‑based environments into robust, production‑grade C++.

This is less about algorithm design, more about

engineering systems that make those algorithms run fast, reliably, and at scale .

What You’ll Be Doing

Develop high-performance software primarily in

C++

for compute-intensive applications

Translate and optimise

Python‑based tooling

into efficient, production‑grade systems

Design clean, scalable architectures for performance-critical environments

Profile and optimise code (multi-threading, memory management, vectorisation)

Work closely with cross‑functional engineering teams to ensure software integrates seamlessly into wider systems

Improve tooling, testing, and overall developer workflows

What They’re Looking For

Strong commercial experience in

C++ (modern standards preferred)

Solid working knowledge of

Python

(for tooling, prototyping, or legacy systems)

Experience building

high-performance, scalable software systems

Strong understanding of software architecture, data structures, and performance optimisation

Comfortable working close to hardware or in complex engineering environments

Why It’s Interesting

Work on genuinely complex engineering problems where performance matters

High ownership and real impact on core systems

Collaborative, engineering‑first environment
