Together we’re building a world-class platform to amplify our teams’ most powerful ideas.\nSecurity is foundational to this mission and must be delivered in a way that supports how our engineering teams build and operate complex systems at scale.\nTake the next step in your career.\nThe role\nThe Core IP Security team designs, builds and operates the bespoke security systems that protect the firm’s most sensitive intellectual property across its full lifecycle, from research through to production systems.\nOur systems are purpose-built for highly sensitive environments and include cryptographic key management, encrypted source code and document hosting, access control and approval workflows, classification and risk-reporting, and detection and scanning tools.\nAs a Software Engineer, you will take ownership of designing, developing and operating these systems across service backends, cryptographic libraries, API integrations and hardened infrastructure. The software you build must meet the highest standards of correctness, auditability and availability.\nYou will work on both new capabilities and improvements to existing systems, partnering closely with research stakeholders to deliver effective security controls that support workflows without creating unnecessary friction.\nThis is a hands-on role with significant autonomy in a small, focused team where every engineer has a meaningful impact.\nKey responsibilities\nKey responsibilities of the role include:\nDesigning and implementing high-assurance security systems to protect sensitive and valuable intellectual property\nDeveloping and maintaining cryptographic key management services, access-control policies and shared security libraries\nBuilding and evolving access control, classification and risk-reporting systems to support governance and auditability\nDeveloping APIs and integrations that embed security controls into the wider engineering platform\nContributing to detection and scanning capabilities to identify protected assets and validate controls\nOperating and hardening security-critical infrastructure, including physical server environments with dual-control operational procedures\nParticipating in disaster recovery planning, testing and execution for critical security systems\nIdentifying opportunities to simplify, replace or rebuild existing systems when better approaches are available\nWho are we looking for?\nWe are looking for an engineer who combines strong software development skills with an interest in security, cryptography and high-integrity systems. You should be comfortable working across the full stack, from service backends and APIs to cryptographic libraries and infrastructure automation in a collaborative, fast-moving environment.\nThe ideal candidate will have the following skills and experience:\nEssential:\nStrong experience delivering production-quality software, ideally using C#/.NET\nStrong understanding of software architecture, concurrency, distributed systems and API design\nExperience building or operating security-sensitive systems where correctness and auditability are critical\nSound engineering judgement, balancing security, performance, reliability and delivery\nClear communication skills and a collaborative, pragmatic approach\nExperience with modern development practices, including CI/CD, code review and automated testing\nHighly desirable:\nExperience with cryptography, key management or security-sensitive infrastructure\nExperience with hardened environments, operational controls or shared security components\nFamiliarity with access control, identity management or approval workflow engines\nStrong Linux, infrastructure automation and Kubernetes experience, including infrastructure as code and observability tooling\nFull-stack development experience for internal tools and dashboards\nNice to have:\nExperience with Python, TypeScript, Go or Rust\nExposure to threat modelling, remediation or security architecture reviews\nExperience in regulated or security-conscious environments\nFamiliarity with Git internals, self-hosted Git platforms or source code management security\nWhy join us?\nHighly competitive compensation plus annual discretionary bonus\nLunch provided via Just Eat for Business and dedicated barista bar\n35 days’ annual leave\n9% company pension contributions\nInformal dress code and excellent work-life balance\nComprehensive healthcare and life assurance\nCycle-to-work scheme\nMonthly company events\nG-Research is committed to cultivating and preserving an inclusive work environment. We are an ideas-driven business and we place great value on diversity of experience and opinions.\nWe want to ensure that applicants receive a recruitment experience that enables them to perform at their best.
