Senior Full Stack Developer / Tech Lead (K/M)

Date: Sep 10, 2026

Location: Gliwice, PL

Company: Tenneco

Tenneco is a global automotive company undergoing a digital transformation to meet the demands of today's market and growing competition.

Our engineering team develops advanced web applications - engineering calculators, data processing pipelines, dashboards, and AI solutions - used daily by engineers in technical centers around the world.

We don't build software for the shelf - our applications are used every day and directly affect how fast engineers get their work done. We build them on a modern stack, with no legacy systems to maintain and no technical debt to work around, and we intend to keep it that way.

We are building our platform as microservices, so solid experience with that style of architecture - and the strategies that come with it - is essential. We are looking for an experienced developer to design and deliver the next generation platform.

Who We're Looking For

 

We are looking for a self-sufficient Full Stack Developer with leadership skills who:

  • Owns the whole development process - the idea, the architecture, the technology and UI decisions, the implementation, and the delivery
  • Builds complete applications - frontend, backend, and the infrastructure they run on
  • Holds the team to a high standard - reviews code, defines how things are done, and keeps improving it
  • Works efficiently with GitHub - branching strategies, pull requests, CI/CD pipelines
  • Responsibilities
  • Work with stakeholders across different teams to understand what they need, propose solutions, and turn requirements into a concrete plan - including bringing in new ideas of your own
  • Build and ship the solution: frontend, backend, and infrastructure - owning the architecture, technology choices, containerization, and deployment to production
  • Review code, define development standards, and hold the team to them
  • Mentor junior developers and continuously improve both the team and the platform
  • Design and build AI agents and AI-driven automation that remove manual, repetitive work from engineering processes

 

 

Required Qualifications

  • Min. 5 years of commercial full stack development experience
  • Strong hands-on experience with Python (Django, FastAPI) and React
  • Hands-on experience with Docker - building and shipping containerized applications to production
  • Git and GitHub - branching strategies, pull requests, CI/CD pipelines
  • Experience designing and building microservices and event-driven architecture
  • English min. B2 - used daily

 

 

Nice to Have

  • Deploying applications to AWS (ECS, ALB, S3)
  • Python packages for data science - NumPy, SciPy, Pandas, Plotly
  • AI agents - Strands Agents, Google ADK, LangChain, AWS Bedrock AgentCore
  • CAE simulation software - Abaqus, Ansys, AMESim
  • Terraform / Infrastructure as Code
  • Previous Tech Lead or Architect experience
  • Engineering background

 

 

What We Offer

  • Challenging and meaningful work - building software that truly changes how engineers work
  • Collaboration with a team of CAE and computer simulation experts
  • Global impact - your software will be used in technical centers worldwide
  • Real influence on architecture and technology choices
  • Participation in the digital transformation of a global company
