Senior Python Engineer, Tampa On-site

Lead Python 3.12 migration work, including runtime upgrades, dependency updates, and compatibility testing. Contribute to MAS Global Consulting’s digital engineering projects for startups and Fortune 100 companies.

Description

  • Prepare migration pull requests for assigned packages and services in line with the team’s Python 3.12 upgrade plan.
  • Address dependency and build compatibility problems by adjusting version constraints and replacing deprecated or unsupported libraries.
  • Check upgrades with unit, integration, and runtime compatibility tests; investigate failures and record evidence to support a safe rollout.
  • Refine migration scripts, build settings, linting, and static checks so recurring upgrade work is safer and easier to review.
  • Coordinate with package and service owners on review feedback, monitor progress and blockers, and raise issues that need broader platform changes.
  • Join the platform engineering team carrying out a Python 3.12 migration across a large codebase.

Requirements

  • At least five years of professional Python experience, maintaining production services or shared libraries in a large codebase.
  • Advanced English proficiency (B2/C1) is required, along with strong written and spoken communication.
  • Strong command of Python packaging and build tools, including dependency resolution, version constraints, virtual environments, and package compatibility.
  • Practical experience upgrading Python runtimes and libraries, diagnosing version-related behavior changes, and handling transitive dependencies.
  • Experience using linting, formatting, and static analysis in CI/CD pipelines.
  • Strong testing and debugging ability, including separating migration regressions from unrelated failures.
  • Experience with large refactors, staged runtime rollouts, or coordinated dependency upgrades across many packages and services.
  • Familiarity with native Python extensions, compiled dependencies, or compatibility issues on Linux and Apple Silicon.
  • Experience creating reusable migration scripts or automation to reduce repetitive upgrade work.
  • Experience in developer productivity, build and test infrastructure, or platform engineering teams.
