Ask HN: Who is hiring? (February 2025)
Langfuse (https://langfuse.com) | Backend Engineer, Product Engineer, Design Engineer | Berlin Germany | in-person | Full-time
I'm Max, co-founder and CTO of Langfuse (YC W23) - we're building open source LLMOps dev tooling (Github: https://github.com/langfuse/langfuse/). We started with observability and have branched out into more workflows over time (evals, prompt mgmt, playground, testing...). We have a bunch of traction and are looking for our fourth to sixth hire in scaling and building feature depth. We're hiring in person (4-5 days/week) in Berlin, Germany (salary ranges for each job 70k-130k, up to 0.35% equity).
We value quality in engineering at Langfuse: We try to find elegant solutions to complex engineering challenges, and we invested significant effort in enhancing our production setup (infra as code, top observability setup and more).
If you'd love shipping in open source, writing about what you work on and working hard with super interesting and sophisticated customers (devs) - reach out!

Show HN: Houseplant – Database Migrations for ClickHouse
This is interesting! Do you plan to add support for distinguishing between blocking and non-blocking/async migrations? This seems to be a common challenge when using Clickhouse and needing to change the ordering of existing tables.
Context: When adding Clickhouse to Langfuse [1] to store all observability data, the migration DX was a big challenge. Some migrations need to copy/reorder data between tables which can take a long time and thus need be performed in the background/async. Many teams run Langfuse self-hosted and reducing downtime of an upgrade is important, thus, we added some custom logic to run these “background migrations” for now [2]. For regular migrations we use golang-migrate, works decently although DX isn’t as good as eg Prisma for Postgres.
