About Neptune North

Neptune North is a high-performing technical consultancy. We build data, AI and software solutions for clients in defence, financial services and private capital, working on demanding problems in challenging environments.

We were founded in 2024 as a joint venture between Oliver Wyman and Rokos Capital Management. We’re headquartered in the centre of Newcastle upon Tyne, with a growing international footprint, and we’re recruiting exceptional engineers across every level.

The role

We’re looking for a Senior Software Engineer to lead low-level and embedded development on demanding defence projects and to help provide technical oversight to a new and rapidly growing team. You will help define and strengthen the systems engineering capabilities that differentiate Neptune North and build a trusted reputation across defence clients.

Responsibilities also include contributing to business development, providing technical expertise and mentoring, overseeing the quality of deliverables, and hands-on involvement in projects.

This is a technical leadership role for an engineer who wants to stay close to the code. Potential projects span fully engineered solutions, developing Proof of Concepts (POCs), and applied work on embedded, real-time and resource-constrained platforms.

Responsibilities

• Influence the technical direction and play a key role in strengthening Neptune North’s low-level and embedded capabilities
• Provide leadership and hands-on delivery in a wide range of systems projects
• Set and maintain technical direction, architecture and standards, and make pragmatic trade-offs between speed, quality and long-term maintainability
• Run code and design reviews, set the bar for quality, and hold the team to it
• Work directly with clients to shape requirements, manage expectations, and to build trust
• Contribute to winning work by helping to write compelling bids and high-quality technical proposals
• Demonstrate flexibility in taking on work aligned to evolving company priorities
• Advocate knowledge sharing across the team and identify opportunities for reuse of capabilities
• Regularly provide career and technical mentorship to other engineers to build a high calibre engineering team
