Software Engineer, C++ Developer

hackajob is collaborating with Core Tech Security to connect them with exceptional tech professionals for this role.

Our Capability Development team develops bespoke software for our clients in the Cyber Security domain. We specialise in C and C++ and have worked across iOS, Android, Windows, macOS and Linux. We emphasise having a comprehensive understanding of the programming languages, platforms, and tooling we rely on, and are looking for a candidate who holds an active Developed Vetting security clearance to join our team.

That deep technical knowledge has helped us earn a reputation for writing novel, robust, and maintainable solutions to our client's challenging and fascinating problems! Our projects are typically delivered by 2-4 person teams over months, rather than years, with daily opportunities to see the direct impact of our work.

We're led by engineers and empowered to optimise our (lightweight!) development processes with the knowledge gained from each project.

As part of our team, you may:

• Design a new clean‑slate product with complete autonomy over its architecture.
• Add new capabilities to, or replace a core component of, an existing product.
• Throw together a quick‑and‑dirty prototype to confirm the feasibility of a proposed technical approach; iterating until it meets requirements.

For this role you'll be hands‑on in the day‑to‑day delivery of projects. Typically, this will see you working with one or two other colleagues at a time. In addition, you'll take an active role in unlocking the potential of junior colleagues: encouraging idiomatic code, demonstrating engineering rigour, and sharing hard‑won knowledge with your peers. You’ll also help drive our engineering processes to maintain code quality while balancing realistic delivery timescales and client requirements.

• Professional experience in the design and implementation of complex C or C++ based solutions, ideally both clean‑slate projects and updates to legacy code bases.
• Comfortable with platform APIs, development environments and native debugging approaches on one or more of:
  Windows, macOS, Linux, iOS, or Android.
• Experience leading a small or midsize team of developers through a complete project lifecycle, engaging in requirements capture, design review, implementation, and assurance.
• Commitment to code correctness and quality assurance through static analysis, code review, automated testing, and continuous integration.

This vacancy is for experienced software engineers and will require skills and experience in several of the areas listed as well as the ability to lead technical projects. If you do not meet these requirements please check our other vacancies which have different skills requirements.

• Promotions are based on technical excellence and reviewed regularly.
• 25 days holiday per year (with bank holidays on top), option to buy up to 5 days per year.
• Level up with an extra day of holiday per year, up to an extra 5 days, starting from 2 years' service.
• We offer financial support to cover HMRC allowable costs of relocating if you’re moving to the area.
• Training and development opportunities to support your career aspirations.
• O'Reilly books subscription which provides access to huge range of technical books.
• Regular events including internal technical conferences, company socials and pizza‑fuelled lunchtime seminars.
• Free seasonal fruit, tea, coffee, milk, squash and hot chocolate.
