We trust people: we offer autonomy, continuous support, and a collaborative environment where you can grow without limits. We are one general team, guided by respect, integrity, and a passion for doing better every day. Job Description Key responsibilities Analyse repositories for maintainability, dependency risks, hidden coupling, insecure patterns, build fragility, licensing signals, and documentation gaps relevant to due diligence. Use AI coding agents to accelerate code review preparation, vulnerability explanation, remediation proposal drafting, and technical debt clustering across large codebases. Run and interpret quality, dependency, secret, container, and infrastructure scanning tools while documenting false positives, residual risks, and required expert review. Support reproducible build and release validation by analysing logs, pipeline definitions, container images, package sources, artefact flows, and configuration assumptions. Create evidence packs that link findings to code locations, tool results, reviewer decisions, risk severity, mitigation options, and readiness implications. Collaborate with security, Dev Ops, architecture, and test specialists to ensure AI-assisted validation results are actionable and aligned with enterprise assurance expectations. Examples of market tools, models, and SDLC platforms expected AI coding and review environments such as Cursor, Windsurf, Claude Code, Continue, Cline, Aider, or VS Code-based assistants connected to approved model endpoints. Open-source or Chinese coding-capable models such as Deep Seek Coder, Qwen/Qwen-Coder, Code Gee X, Star Coder, Code Llama, Mistral, or similar internally hosted models. Quality and security tooling such as Sonar Qube, Semgrep, Trivy, Git Guardian, Syft, Grype, dependency-check, Falco,



SBOM tooling, and container/image scanners. Engineering environments including Git Lab, Git Hub Enterprise, Jenkins, Kubernetes, Helm, Docker, Argo CD, package registries, Python tooling, and log analysis workflows. Qualifications 5+ years in software engineering, secure development, Dev Sec Ops, platform engineering, or quality-focused engineering roles. Strong Python skills plus practical experience in at least one backend or systems language such as Go, Java, C, C++, or Rust. Hands‑on experience with code review, vulnerability triage, dependency analysis, CI/CD inspection, container security, or software supply‑chain evidence generation. Practical experience using AI coding assistants for code understanding, documentation, remediation proposals, test generation, or large-repository review acceleration. Good understanding of Open Stack‑derived cloud platforms, distributed services, Kubernetes, Linux, and enterprise build and release processes is strongly preferred. Comfortable producing concise, evidence‑backed findings in high‑accountability environments where confidentiality, auditability, and reviewer judgement are essential.
