database engineer

turbopuffer is looking for database engineers who want to advance the frontier of search.

what you'll do:

• design and implement improvements across one or more layers of our search engine (storage, indexing, querying)
• intensive performance hacking: tracing, CPU/heap profiling, optimizing data structures, using SIMD, tuning IO pipelines, etc.
• evolve our search primitives and APIs (full text + vector + reranking)
• work closely with customers to win their workloads and fold learnings back into the product
• write crisp docs

must have:

• systems engineering
• you've worked extensively in a systems language (Rust, C++, Java, Go, etc.)
• you think in memory layouts, cache lines, and syscalls
• you methodically work through problems until you've found the root cause
• domain expertise — you're an expert in at least one of the following domains
• search internals (e.g., inverted indexes, ANN indexes, rerankers)
• storage engines (e.g., LSMs, WALs, MVCC, compaction, GC)
• distributed systems (e.g., replication, leases, fault injection, simulation/chaos testing)
• linux — you're at home in terminals, eBPF/perf, strace, gdb
• typist — you can write well and explain complex ideas simply
• human — you build trust and admit what you don’t know

nice to have:

• multiple years of experience writing Rust
• you've maintained or operated serious systems in production, at scale
• you've made interesting contributions to the databases, IR, or systems communities (e.g., research, open source, speaking)

•

additional domain expertise in:

• k8s and cloud infra (GKE/EKS/AKS, disks and networking, load balancers, observability)
• security (multi-tenant systems, isolation, sandboxing)

tpuf is hardcore & whimsical. we value:

• overstep understep
• show tell
• complexity is earned
• showing up as part of our customer’s team
• making stuff easy to react to
