ParadeDB | https://paradedb.com | SF Onsite + Remote | Full-Time | Rust Database Engineers

ParadeDB is an alternative to Elasticsearch built on Postgres. We're building a Postgres extension in Rust that offers a new index type optimized for full-text search and aggregate/analytics workloads. We solve three problems with Elasticsearch today:

- Lack of read-after-writes guarantees

- Lack of JOINs

- Infrastructure complexity & cost due to syncing Postgres and Elastic.

We're open-source, and our repository is available at https://github.com/paradedb/paradedb. We're a Series A team of 8 distributed across the US and Canada. Most folks on our team have 10+ years of experience in database internals at companies like Twitter, MongoDB, Oracle, Instacart, etc.

You can find our roles and the profiles of our team members here: https://paradedb.notion.site

If you know Rust and/or have experience working on DB internals and want to work on cool systems problems, shoot us a note. We hire with conviction, have lots of room to grow, and exciting technical problems to solve. My email is Email is hidden.

Aloe | Vancouver, BC, Canada (ONSITE preference)

Aloe is the critical thinking layer for agents – to know why they believe what they do, how confident they are, and what actions they can take to increase that confidence. It’s the only path to AI we can trust, delegate to, and rely on.

Aloe exists to build tools to help human cognition succeed in an information-dense world it did not evolve to handle. We believe this is the most important problem to solve today.
