We are seeking a Senior Python Developer to join our team working on enterprise platform engineering initiatives. This role focuses on brownfield modernization, security remediation, and AWS serverless infrastructure supporting internal tooling and integrations across the vehicle lifecycle domain.

Responsibilities

• 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

Requirements

• 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)

Nice to have

• GHA migration
• Familiarity with ServiceNow
• Understanding of Snowflake
