Tiger Data (FKA Timescale) [ Global | 100% Remote | Multiple Roles: Eng, Product, Support + more ]

We began in 2017 as TimescaleDB, focused on making PostgreSQL the best database for time-series data. As our customers evolved, so did we.

Today, more than 2,000 companies use our technology to power real-time analytics, agentic applications, and high-ingest operational systems. What started as a time-series database has become the fastest PostgreSQL for modern workloads. To reflect that evolution, we’re now TigerData—a name that speaks to our speed, precision, and ambition. The tiger has long been part of our culture: fast, focused, powerful. From “Tiger Time” all-hands to welcoming new hires as “tiger cubs,” it’s how we build—decisively, fearlessly, and with purpose.

This is not a reinvention: it’s a reflection of how we already serve our customers today.

px dynamics GmbH | Senior System Engineer, Full Stack | Full-time | Berlin/Cologne/Hybrid | https://www.pxdynamics.com/

Background: px dynamics was founded by me less than half a year ago, I have 15 years experience in short term power trading in European markets, esp. algo trading. I do some consulting to bootstrap the company with and build customer relations. Simultaenously, we're starting to build a product business. For that we have strengthened the team with a Senior ML Engineer (ex google) and a Head of Data with prior experience in setting up data pipelines in this domain. The products we build are in a broad sense trading signals, e.g. to help traders of renewable or flexible assets trade their positions better.

Role: So given that it is pretty early days, we're of course looking for a broader skillset to lead the development especially of the cloud and backend infrastructure (hetzner), but eventually also frontend applications. Techstack so far is obviously minimal (linux, python, bash, postgres/timescale), so there is plenty of room to also shape this. What we as a team value is simplicity, really clean code/architectures, excellent documentations and quality over speed. So we're not trying to glue together the next venture to scam a bunch of VCs, but to really build something excellent.

if that resonates with you, please reach out to me directly via the email address you'll find on our website.
