Senior C++ Engineer - Core Codecs (Immersive Media / Point Cloud Compression)

London (Hybrid, 3 days/week onsite)|

Permanent, Full-time|

We're hiring a Senior C++ Engineer to join a small, expert team building next-generation compression tools for immersive 3D and point cloud content. You'll be working on the core codec libraries that enable high-fidelity six-degrees-of-freedom (6DoF) playback for VR/AR platforms - helping compress massive volumetric datasets into streamable, real-time formats.

This is a high-impact, greenfield role ideal for someone with deep C++ experience, a performance mindset, and an interest in 3D data or immersive tech. You'll work closely with low-level engineers and leadership, contributing directly to production-grade encoder/decoder pipelines.

What You'll Do

Design and implement core compression algorithms in modern C++ (C++17 or later)

Rewrite and professionalise a research-grade codebase for production use

Optimise low-level memory and performance across multiple platforms

Contribute to CI pipelines, benchmarks, and integration with GPU-based playback systems

Collaborate with content, research, and playback teams across the ecosystem

Provide technical mentorship and code reviews in a fast-moving, collaborative environment

What We're Looking For

Strong experience in modern C++ (C++17/20), ideally in production environments

Hands-on background in performance-oriented development (memory, threading, profiling)

Exposure to compression (any domain - video, signal, point cloud, etc.)

Experience with low-level algorithm design and optimising data-heavy pipelines

Comfortable working in a fast-paced, collaborative team with minimal red tape

Bonus: familiarity with 3D/volumetric data, spatial transformations, or immersive formats

Why Join?

Contribute to genuinely innovative, market-defining technology

Work directly with senior technical leadership in a flat, hands-on team

Focus on deep engineering challenges without heavy process or politics

Help shape the future of how immersive 3D content is delivered and consumed

Enjoy full benefits including healthcare, pension, stock options, and more

Location & Flexibility

Hybrid: 3 days/week onsite in Central London

Sponsorship and relocation are available
