Senior Backend / Platform Engineer | London or Berlin
hn · HYBRID
Jose is a proven founding engineer with deep full-stack systems experience, strong distributed systems credentials (emergency response infrastructure, real-time voice platforms at scale), and demonstrated ability to own complex systems end-to-end. His Python expertise, infrastructure work with Kubernetes/Docker/Terraform, and experience optimizing for performance and reliability align well with Tower's needs. However, he lacks specific experience with query engines, Iceberg, or the data-platform domain that would make this a perfect match, and his recent focus has been more on LLM/AI products than core infrastructure systems.
Hook: Your background shipping real-time systems at scale and owning infrastructure decisions across multiple domains makes you a strong fit for building Tower's serverless data platform runtime.
Missing: Apache Iceberg experience, Query engine development, Data platform architecture, Async Rust expertise, Kubernetes internals knowledge

Tower (tower.dev) | Senior Backend / Platform Engineer | London or Berlin | HYBRID | Full-time Tower is a Python-native serverless data platform. Data teams write plain Python, and we handle packaging, dependency resolution, scheduling, and execution across a serverless runtime built on Apache Iceberg. There's no clusters to manage, no YAML to write, no pipelines to rewrite to fit someone else's engine. If you've ever wanted your local Python script to just run in production at scale without a Databricks detour, that's the product. We're a small, senior team split between London and Berlin. We've built a lot of tech: Custom run dispatch service, multi-region routing, storage based on Apache Iceberg, and the runtime itself, to name a few. This is deep systems work--things like scheduling, distributed execution, and performance. We're not gluing SaaS together. Stack: Go and Rust for the platform, Python everywhere it matters, Kubernetes (EKS + Karpenter) on AWS, RDS Postgres, ElastiCache Redis, S3/Iceberg, WorkOS for auth. Looking for: * strong distributed-systems fundamentals * comfort owning a system end to end * taste for correctness under load Bonus: data-platform, query-engine, or Iceberg experience; async Rust; Kubernetes internals.
