Senior Software Engineer

Senior Engineer Strategic Initiatives (R&D)

Mimecast's AI First engineering organization is looking for a Senior Engineer to contribute to the build and prove layer of the AI Native Engineering function. In this role you will help grow reusable patterns, build agentic prototypes, and improve visibility for stakeholders across the R&D organization.

What You'll Do

• Build and iterate on reusable tooling and automation that accelerate AI Native development across Product and R&D.
• Develop and prototype agentic system patterns that demonstrate production viable approaches for engineering teams to adopt.
• Evolve internal visibility and measurement systems to give leadership actionable insight into AI Native progress and impact.
• Collaborate with teams to surface emerging challenges, bottlenecks, and opportunities as workflows mature.
• Contribute reusable, well documented "paved roads" that emphasize architecture and security alignment, reducing experimentation costs.
• Share knowledge through documentation, examples, and hands on support to help teams apply patterns effectively.
• Surface observations and insights from day to day work to inform strategic direction and priorities.

What You'll Bring

• Strong hands on software engineering skills with a proven track record of shipping production quality tooling, automation, and integrations (e.g., Python, TypeScript, or similar).
• Solid DevOps and platform engineering fluency; experience with CI/CD pipelines, infrastructure as code, and modern delivery toolchains.
• Working knowledge of secure development practices and the ability to integrate security considerations into tooling and architectural patterns.
• Full spectrum engineering background across multiple disciplines (QA, tooling, platform, application development).
• Strong communication and facilitation skills; comfortable explaining technical work and collaborating across teams.
• Demonstrated ability to work autonomously, prioritize competing demands, and drive initiatives forward without close direction.
• Evidence of initiative and impact beyond immediate team responsibilities.

Qualifications

• Mid to senior level engineering experience with evidence of growing scope and initiative.
• Experience in cybersecurity, email security, or adjacent enterprise SaaS domains preferred.
• Familiarity with AI/ML concepts, including prompt engineering, model evaluation, retrieval augmented generation, and agent orchestration frameworks, is valuable but can be developed in role.
• Prior experience in a developer enablement, developer experience, internal tools, or platform engineering function preferred.
• Experience contributing to internal tooling, shared engineering infrastructure, or developer facing platforms that serve a broad engineering organization is a plus.

Salary and Benefits

The base salary range for this position is £80,000-£120,000, plus benefits. The range represents minimum and maximum new hire compensation for this role and may be augmented with incentive plans and additional benefits in accordance with company policy and local regulations.
