About the role
A Product Engineer at Langdock owns features end to end. You take a customer problem, scope it, design the solution, build it across the stack, ship it, and stay close to it after release.
What you'll do
- Work across main product surfaces: Chat, Agents, Workflows, Mobile and admin tooling
- Build infrastructure and product surfaces for evaluating agent behavior, comparing runs, and catching regressions
- Develop systems for organizing attachments and files, making knowledge retrievable and governed over time
- Create governance features for agents in enterprise workspaces, managing creation, usage, sharing, and auditing
- Build Excel and Outlook plugins that bring Langdock into enterprise tools
- Pick up an area of the product and shape where it goes next
What you'll need
- 3 to 6 years of full-stack experience shipping production software people actually use
- Strong in TypeScript, React, and Node. Comfortable with Postgres, Redis, queues, and async work
- Very driven, with high standards for yourself, moving fast without needing to be pushed
- Close to users, understanding why people behave the way they do and using that to make product decisions
- Able to take a vague problem to a shipped feature: scope, decide, implement, test, and iterate
- Working understanding of how LLMs behave: context windows, tool calling, streaming, and differences between major providers
- Heavy user of AI tooling in your own development workflow with opinions on what works and what does not
- Demonstrated ability to ship things end to end through side projects, open source, or products with real users
What they offer
- Top of market compensation with transparent levels and equity for all roles
- Full-time in-office role in Berlin with collaborative engineering environment
- Opportunity to join customers on-site and sit with real users during hackathons or workshops
- Freedom in AI tools to use in your workflow and strong harness for AI-assisted shipping
