Your tasks

We’re looking for a Senior Tech Lead to guide technical design and delivery for a Cybersecurity engineering squad. This position blends hands‑on engineering with technical leadership, ensuring robust, secure, and scalable software delivery.

As a key member of the Cybersecurity Assessment & Testing team, you’ll design and deliver Python‑based microservices, integrations, and APIs supporting data, automation, and vulnerability management solutions. You’ll also help introduce AI-assisted engineering and AI‑enabled features that improve detection, prioritisation, and automation within cybersecurity products.

  • Lead technical delivery and architecture for engineering squads, providing guidance, unblocking engineers, and ensuring high‑quality outcomes.
  • Design and build microservice‑based services, REST APIs, and integrations for cybersecurity use cases.
  • Drive DevSecOps practices, including CI/CD pipelines, observability, documentation, and service reliability.
  • Implement and coach secure‑by‑design development approaches, ensuring compliance and resilience.
  • Build and optimise automation, pipelines, and container deployments (Docker, Kubernetes).
  • Develop AI‑powered components and workflows that enhance security operations (triage, summarisation, anomaly detection).
  • Promote responsible adoption of AI coding tools and automation within development teams.
  • Mentor other engineers through code reviews, pairing, and design sessions while maintaining hands‑on coding responsibilities.

Requirements

  • Strong Python engineering expertise (preferably with FastAPI; Flask or Django also welcome).
  • Proven experience delivering production‑grade REST APIs and integrations.
  • Solid background in microservices and distributed systems design.
  • Proficiency in Docker, Kubernetes, Linux administration, network fundamentals (TCP/IP).
  • Experience with CI/CD pipelines (Jenkins, GitLab, GitHub Actions) and test automation.
  • Excellent Git fluency and knowledge of branching strategies.
  • Strong SQL skills and database interaction experience.
  • Demonstrated ability to lead technical teams, make engineering decisions, and uphold coding standards.
  • Hands‑on experience with AI‑enabled software (e.g. ML/NLP, LLM‑based tools, or applied AI workflows).
  • Clear and structured communication across technical and non‑technical teams.

Nice to have

  • Cybersecurity engineering experience (SAST/DAST integration, threat detection, pen testing concepts).
  • Cloud delivery experience (AWS, Azure, GCP) and IaC (Terraform).
  • Exposure to monitoring tools (Prometheus) and service meshes.
  • Front‑end experience (React, JS frameworks).
  • Familiarity with Kafka, RabbitMQ, PostgreSQL, MSSQL, MongoDB.

Must have: Flask, Django, REST API, Microservices, Docker, Kubernetes, Linux, TCP, CI/CD Pipelines, Jenkins, GitLab, GitHub Actions, Test automation, Git, SQL, AI, ML, NLP, LLM
