• Design, build, and maintain AWS Lambda services and API Gateway endpoints using Python and Boto3
• Lead the CI/CD migration from legacy pipelines to GitHub Actions workflows
• Manage infrastructure as code using Terraform (primary) and Serverless frameworks
• Execute brownfield refactors, service decommissions, and migrations — e.g., OAuth migrations, WAF block-mode enablement, SAST/SCA remediations
• Configure and tune AWS WAF rules; resolve security findings surfaced by SAST and SCA tooling
• Integrate internal and third-party systems via REST APIs (e.g., OAuth client credentials flows)
• Automate operational workflows and support agentic platform initiatives (n8n, LangChain, or equivalent orchestration tools are a plus)
• Collaborate with the SRE Consultant on telemetry gaps and Lambda-based data collection automation
• Work in a spec-driven SDLC
• Develop AI-driven improvements to design, delivery, and triage practices
• Evaluate new tooling and solutions as candidates for enterprise-level AI enablement offerings

• 3+ years of Python development with a focus on AWS Lambda and API Gateway in production environments
• Proficiency in Boto3 across IAM, Secrets Manager, and SSM, as well as Lambda, API Gateway, CloudWatch, and WAF
• Expertise in Terraform for IaC in production, with the ability to write, refactor, and review modules
• Background in Serverless Framework, including maintaining and migrating legacy stacks
• Knowledge of AWS WAF rule configuration, block-mode enablement, and incident response
• Familiarity with security tooling such as SAST and SCA, and exposure to a structured compliance programme
• Brownfield mindset — proven track record of migrations, decommissions, and refactors rather than greenfield builds
• Proficient communication skills in English (B2 level or higher)
