Paid summer 2027 cybersecurity research internship involving vulnerability research, ethical hacking, reverse engineering, and bespoke security capability development. Interns work in small teams on technically challenging client projects. Useful skills include C/C++/Java, Python scripting, Linux shell, networking, Ghidra, Android, hardware hacking, and Capture the Flag participation. Accommodation is provided in Cheltenham.

Integrate software, hardware, networks, infrastructure, and third-party technologies into reliable working systems. Develop test environments, deployment automation, and tooling; execute system-level tests for functionality, performance, resilience, and failure handling; investigate cross-component faults; and support demonstrations, trials, deployments, and customer acceptance. The role requires hands-on troubleshooting across software, operating systems, networks, configuration, and hardware, with Python or Bash scripting and strong systems integration fundamentals.

Principal Systems Engineer responsible for architecting complex multidisciplinary systems across software, hardware, networks, and third-party technologies. The role covers requirements engineering, system architecture, interface management, technical trade-offs, integration, verification, validation, customer acceptance, and technical risk management. The engineer will act as technical authority on major projects, lead engineering practices, mentor colleagues, and maintain hands-on involvement throughout delivery.

Provide back-office support to consultants and project teams, managing procurement, financial administration, and project processes. Maintain accurate data, prioritise tasks, suggest and implement process improvements, and collaborate with Commercial and Operations teams. Primarily office-based in Cheltenham with flexible hours or part-time options.

Conduct vulnerability research, reverse engineer proprietary binaries, audit C and C++ code, develop exploit proof-of-concepts, and create novel tools for security research. The role focuses on Android and iOS internals, ARM-based architectures, Linux, exploitation techniques, and ethical hacking. Researchers collaborate with software engineers, solve complex technical problems, lead technical projects, and deliver bespoke cybersecurity solutions for sensitive clients.

Conduct cybersecurity research focused on vulnerability discovery, reverse engineering, hardware teardown, ethical hacking, and cyber engineering. The role involves solving complex research problems, rapid prototyping, software engineering, and developing bespoke security solutions for clients. Graduates receive structured training, mentoring, and shadowing through the CoreTech Academy, with opportunities to build expertise in bug hunting and reverse engineering.

Conduct offensive vulnerability research and reverse engineering against mobile operating systems and embedded devices. Develop exploit proof of concepts using C, C++, Python, or assembly; analyze binaries with Ghidra; investigate code execution, privilege escalation, and exploit mitigations. Participate in the CoreTech Academy through training, mentoring, and shadowing while solving complex security research problems.

The role involves vulnerability research, reverse engineering, auditing code, and developing innovative security solutions for clients. Candidates should have expertise in ethical hacking and bug hunting, with a strong focus on problem-solving.

The High-Integrity Software Engineer will design products, enhance existing solutions, prototype technical approaches, and mentor junior team members while ensuring robust code quality and project delivery.

Join CoreTech's R&D team as a graduate software engineer enrolled in the CoreTech Academy. You'll learn native multi-platform development, debugging and reverse engineering through pair programming, code reviews, mentoring, and hands-on projects. Applicants must submit code for the Operation FIRE STORM challenge. The role emphasizes high-assurance, quality code, teamwork, and preparing graduates for rapid progression in security-focused software engineering.

Conduct cutting-edge cyber security research and rapid prototyping to solve complex problems. Reverse-engineer software/hardware, analyse networks and protocols, develop niche solutions, and collaborate with researchers and engineers to produce real-world impact while continually learning new technologies.

Perform advanced Android security research: reverse engineering, static and dynamic analysis, AOSP builds, firmware/application modification, PoC development, and lead or contribute to research projects delivering exploit proofs and mitigation insights.

Join a vulnerability research team to develop exploits, reverse engineer binaries, bypass mitigations, and productise low-level security solutions across multiple architectures. Collaborate with researchers and engineers to build tools and present technical findings.

Develop and deliver maintainable software across web, native and service environments. Design, prototype, integrate and extend systems, APIs and tooling. Work in small teams, follow engineering best practices (testing, code review, CI), mentor juniors and engage with customers to translate requirements into reliable software.
