Senior/Lead Platform Engineer

About the role

We are looking for a Senior Platform Engineer to provide hands-on engineering support for an internal audit and code-modification platform built on GitLab CI/CD pipelines and LLM-powered agentic workflows. You will execute against an existing backlog, improve system reliability and observability, support telemetry and run management, and enhance the developer experience for reviewing AI-generated merge requests using Python. This is a three-month project engagement.

What you will do

• Provide hands-on engineering support for an internal audit and code-modification platform;
• Execute against an existing backlog;
• Improve system reliability and observability;
• Support telemetry and run management;
• Enhance the developer experience for reviewing AI-generated merge requests using Python;
• Support system maintenance, operational improvements, GitLab pipeline execution, LLM/agentic workflow support, telemetry, logging, run management, and improving the developer experience for reviewing generated merge requests;
• Support internal engineering teams;
• Improve reliability, visibility, and usability of the current system.

Must haves

• 5+ years of strong experience with GitLab CI/CD pipelines, merge request workflows, and pipeline debugging;
• Senior-level backend/platform engineering experience with the ability to maintain and improve existing systems, ideally with Python;
• Experience working with LLM, prompt-driven, or agentic workflows, including input/output validation and deterministic execution patterns;
• Strong understanding of observability, including logging, telemetry, debugging, run tracking, and operational visibility;
• Experience supporting internal developer tools or platforms used by multiple engineering teams;
• Ability to execute tactical improvements independently without requiring re-architecture or extensive direction;
• Comfortable reviewing and improving generated code changes, codemods, and automated merge requests;
• Strong communication skills for supporting internal engineering customers and translating use cases into implementation work;
• Upper-intermediate English level.

Nice to haves

• Experience building or maintaining developer experience tooling for code review, audits, or automated remediation;
• Familiarity with GitHub or GitLab extensions, repository audits, or large-scale source-code analysis;
• Experience with codemod frameworks or automated code transformation across large codebases;
• Experience optimizing LLM token usage, cost tracking, and per-job reporting;
• Knowledge of MCP, internal orchestration systems, or agent gateway patterns;
• Prior experience supporting centralized engineering platforms used across many product teams.
