We are looking for a dedicated Senior Python Engineer to come on board with our team.

This position is centered on improving cloud infrastructure, automation pipelines, and engineering practices in an AWS-oriented environment. The role gives you the chance to lead meaningful migrations, support AI-enabled engineering improvements, and help build secure, scalable platform foundations.

Responsibilities

Function within a spec-driven software development lifecycle
Develop AI-powered enhancements for design, delivery, and triage processes
Examine new tools and solutions as possible candidates for enterprise-level AI enablement offerings
Design, implement, and maintain AWS Lambda services and API Gateway endpoints with Python and boto3
Lead the CI/CD movement away from legacy cicd-functions pipelines toward GitHub Actions workflows
Handle infrastructure as code mainly through Terraform, with support from Serverless frameworks
Carry out brownfield refactors, service shutdowns, and migrations, including OAuth migrations, WAF block-mode rollouts, and Mythos SAST/SCA remediations
Configure and adjust AWS WAF rules while addressing security issues uncovered by SAST and SCA tooling
Improve operational workflows and back agentic platform initiatives, with experience in n8n, LangChain, or comparable orchestration tools regarded as an advantage
Partner with the SRE Consultant on telemetry gaps and Lambda-based data collection automation

Requirements

At least 3 years of relevant professional background
Python development experience focused on AWS Lambda and API Gateway in production settings
Strong working knowledge of boto3 across services such as IAM, Secrets Manager, SSM, Lambda, API Gateway, CloudWatch, and WAF
Hands-on Terraform expertise for production-level infrastructure as code, covering writing, refactoring, and reviewing modules
Practical familiarity with the Serverless Framework, including supporting and migrating legacy stacks
Hands-on construction of CI/CD pipelines in GitHub Actions, with willingness to lead a cicd-functions to GHA transition
Experience defining AWS WAF rules, enabling block mode, and contributing to incident response efforts
Knowledge of security tooling such as SAST and SCA, plus exposure to a structured compliance program
Brownfield approach with a proven history of migrations, decommissions, and refactors rather than greenfield work
Excellent oral and written English communication skills (B2+ level or higher)

Nice to have

Background in linking internal and third-party systems via REST APIs, including patterns such as ServiceNow OAuth client credentials flows
Knowledge of Snowflake for cloud data warehousing, analytics, and data platform integration
