We're building the world's first observability stack for mission-critical hardware sensor data. Founded by engineers who've literally put rockets into orbit, Sift provides unified data pipelines, infrastructure, and analysis tools for complex hardware systems.

Our platform helps aerospace, robotics, and other hardware companies accelerate their engineering cycles by turning "trial and error" into "trial and measure." We work with companies like Reliable Robotics and others pushing the boundaries of autonomous systems and space technology. We're looking for engineers who are passionate about:

- Building scalable data infrastructure for real-time telemetry

- Working with mission-critical systems where failure isn't an option

- Helping the next generation of machines reach orbit and beyond

If you're interested in joining a team that's making hardware development faster, safer, and more data-driven, apply above!

Galaxy (getgalaxy.io) - Cursor for Data | NYC, NY | Full time -- Founding Frontend Engineer -- Founding Machine Learning Engineer We are building the unified data platform, starting with a reimagined, modern, AI-enabled SQL editor - and will move into sharing, collaboration, access controls, and more.

We launched the alpha 3 weeks ago to 100 people on our 2K waitlist (and growing) and the feedback was INCREDIBLE. There is massive pull for this product and NOW is the time to build this :)

Mitch Bregman (linkedin.com/in/mitchbregs), me (Garrett Wolfe - linkedin.com/in/garrettawolfe) and one friend (TBA) started Galaxy as a passion project to solve 3 key problems:

1. Queries everywhere – SQL lives in Slack snippets, BI folders, dusty Git repos, and copy-pasted Notion pages.

2. Never-ending data requests – because no one can find (or trust) the right query, engineers and analytics teams still get pinged for “one more pull.”

3. ChatGPT doesn’t have full DB context - non technical users are writing incorrect SQL that lacks context AND technical users are rewriting the same queries over and over again

LOOKING FOR: We're looking for high agency, high velocity individuals and someone who wants to be part of a family. We are building ~the unified data platform~ and want someone who is excited to be part of the story.
