Explore the boundaries of LLMs and AI, shaping Tessl's direction and transforming the developer experience.
Collaborate closely with our wider engineering team as well as product and design.
Use a bit of jq and grep to quickly navigate a dataset, but recognise when it’s time to use a more robust approach and move the team to something like dbt or duckdb.
Tune a prompt in our generation workflow, eval the results and write an experiment report on your findings.
Rapidly prototype a new language integration for our code generation pipeline, then develop a plan for a scalable implementation.
Factor out a piece of our pipeline to use FaaS, unlocking 1,000x larger evals to run in nearly constant time.
Add support for a new model in our elegant model abstraction library, or rewrite it when new model capabilities prove our existing design wrong.
Work with our platform team on the next generation of eval facilities, based on your understanding of what researchers need and where the platform is heading.

4+ years of experience as a Software Engineer. You care about code efficiency and quality and have firsthand experience in how software is built across teams and environments
Equally comfortable contributing to a mature codebase with strict CI criteria or hacking up a quick notebook to prove/disprove something.
Proven experience collaborating with researchers and bridging between research-focused and engineering-focused teams.
Experience with the applied use of data and statistics, likely to spot and avoid bad data when you see it.
Deeply curious about AI and excited about its potential to transform software engineering.
Nice to have: Education or experience in ML/AI, ideally using unstructured data.
Experience in rapid prototyping environments; Office of CTO, DevRel, etc.
Programming polyglot experienced in several languages of different paradigms (e.g.: Java, JavaScript/TypeScript, Python, C or C++, Haskell or other functional).
