Metabase | https://metabase.com/ | Remote (Global) | Full-time | Applied AI Engineers, Engineering Managers, Frontend and Backend Engineers

Metabase is an open source (https://github.com/metabase/metabase) business intelligence software that lets anyone in your company rummage around in the databases you have. It connects to a number of databases / data warehouses (BigQuery, Redshift, Snowflake, Postgres, MySQL, etc).

Here's a dashboard that has some interesting stats about Metabase: https://stats.metabase.com/public/dashboard/92d6b7ea-7526-48...

People rather like the product (https://metabase.com/love). We're a remote team full of people who care about user experience, making complicated things as simple as possible and building things. We have a deeply pragmatic engineering culture and value building things that people actually use vs whatever closes a deal or makes for a good press release.

Tech stack: Clojure on the backend, Typescript and React on the frontend, Python for the AI services

Sme of these jobs have been open for the last few months. A similar post was even made under the previous month's thread.

Join Acuity Insights’ startup-to-scaleup journey as a Senior Software Developer. In this fully remote role, working within EST and PST time zones from anywhere in Canada, you’ll be part of a team modernizing our assessment platform, Casper. You’ll build new systems, maintain existing systems, lead design, and mentor developers.

Our core assessment product, Casper, provides education programs with a more holistic view of applicants by evaluating their soft skills. Incorporating Casper's insights into the admissions process results in a larger applicant pool, enables student success, and graduates better professionals. Since 2014, Casper has been adopted by over 600 higher education programs, and more than 1 million applicants have registered to take the test.

The systems you’ll work in are mostly JavaScript and TypeScript, though we have some new code in Go. Older apps are Meteor-based monoliths that run on Heroku and store data in MongoDB. Newer apps are React UIs that call well-defined APIs running on AWS API Gateway and Lambda and use DynamoDB.

The role is ideal for a quality-focused full-stack developer with strong technical proficiency who is looking to advance their career with a people-centric company that prioritizes work-life balance, invests in continuous growth, and builds products with meaningful social impact.
