Job description

Build the applications scientists and engineers in biopharma manufacturing use to ask their records questions, check the sources and act on the answers.

You'll build across the Katalyze platform: the screens where experts review what the agents assembled, the services behind them, and the connections to the systems a plant already runs, such as MES, LIMS and quality management systems. Everything we build has to stay traceable, so experts can see where each answer came from and who signed off on it.

You'll join a small engineering team in Toronto and work closely with our AI and deployment teams. You'll ship often, talk to customers, and own what you build from the first commit to production.

The role is hybrid, based in our Toronto office.

What you'll do

• Build features end to end in TypeScript, React and Python
• Design the review screens where experts check sources and decide
• Connect the platform to the MES, LIMS and quality systems customers already use
• Keep the platform fast, reliable and secure as customers and data grow
• Design APIs and data models that keep every record traceable and auditable
• Join customer calls and site visits to see how the product is used
• Review code, write tests and improve how the team ships

What we look for

• Four or more years building web applications in production
• Comfort across the front end, the back end and the data between them
• Clear writing and a bias toward shipping
• Interest in the science behind the work
• Strong TypeScript and React, and working experience with Python
• Experience designing APIs and relational data models, ideally in Postgres

Nice to have

• Experience with regulated software or audit trails
• Experience building products on top of language models or search
• Familiarity with AWS, Docker and infrastructure as code

Katalyze is an equal opportunity employer.
