We are looking for a specialized Senior Python Engineer to join our team.

This role focuses on modernizing cloud infrastructure, automation pipelines, and engineering practices within an AWS-centric environment. The position offers the opportunity to drive impactful migrations, contribute to AI-enabled engineering improvements, and shape secure, scalable platform foundations.

Responsibilities

Operate within a spec-driven software development lifecycle
Develop AI-driven enhancements for design, delivery, and triage practices
Assess emerging tools and solutions as potential candidates for enterprise-level AI enablement offerings
Design, build, and maintain AWS Lambda services and API Gateway endpoints using Python and boto3
Lead the CI/CD migration from legacy cicd-functions pipelines to GitHub Actions workflows
Manage infrastructure as code using Terraform as the primary tool, supported by Serverless frameworks
Carry out brownfield refactors, service decommissions, and migrations, such as OAuth migrations, WAF block-mode enablement, and Mythos SAST/SCA remediations
Configure and fine-tune AWS WAF rules and address security findings surfaced by SAST and SCA tooling
Automate operational workflows and contribute to agentic platform initiatives, with tools such as n8n, LangChain, or equivalent orchestration solutions considered a plus
Partner with the SRE Consultant on telemetry gaps and Lambda-based data collection automation

Requirements

A minimum of 3 years of relevant professional experience
Python development background with a focus on AWS Lambda and API Gateway in production environments
Fluency with boto3 across services including IAM, Secrets Manager, SSM, Lambda, API Gateway, CloudWatch, and WAF
Hands-on experience with Terraform for production-grade infrastructure as code, including writing, refactoring, and reviewing modules
Practical experience with the Serverless Framework, including maintaining and migrating legacy stacks
Hands-on authoring of CI/CD pipelines in GitHub Actions, with comfort leading a cicd-functions to GHA migration
Experience configuring AWS WAF rules, enabling block mode, and supporting incident response
Familiarity with security tooling such as SAST and SCA, along with exposure to a structured compliance program
Brownfield mindset with a proven record of migrations, decommissions, and refactors rather than greenfield development
Excellent verbal and written English communication skills (B2+ level or higher)

Nice to have

Experience integrating internal and third-party systems through REST APIs, including flows such as ServiceNow OAuth client credentials
Familiarity with Snowflake for cloud data warehousing, analytics, and data platform integration
