QuestDB is hiring a North America pre-sales (sales) engineer to support technical validation and drive adoption of its low-latency, open-format time-series database. The company emphasizes extremely high ingest and query performance (millions of events per second, millisecond queries) implemented in Java, Rust, C++ and assembly with columnar, vectorized and JIT-compiled execution. The role owns discovery and time-boxed proofs of concept with reproducible benchmarks on customer data, architecture sign-offs, security reviews and first-production handoffs. It is a hands-on, individual-contributor position working closely with the CEO in New York, the CTO and core engineers, and requires regular presence on the US East Coast (New York-centric) and travel to customer events in New York, Chicago and Toronto.
Day-to-day responsibilities include running technical discovery with engineers and quants, designing POCs with written success criteria, sizing and HA/replication discussions, BYOC on AWS/Azure, Kubernetes, RBAC, TLS/SSO, storage tiering and Parquet queries, and delivering tailored demos and deep dives. The hire must be strong in SQL and database internals, experienced with enterprise evaluations and comfortable leading technical sessions and security/RFI processes. Preferred skills include columnar DB experience, capital-markets tick data, Linux/Docker/Kubernetes, Python plus a systems language, the Python data stack and Grafana. Compensation features equity, flexible hours and high autonomy.

DHH states that agents implemented and optimized the Campfire web app in Elixir, Go, and Rust, with Ruby being the slowest. He emphasizes that productivity and developer joy outweighed speed concerns, but notes that maintainability is important when reading code becomes difficult. (twitter.com)
Build with Python is a beginner course where learners create drawings and interactive projects using Python, including making a robot and click-to-draw paintings. The course covers fundamental programming concepts like functions, variables, loops, and event handling. (scimigo.com)
Software engineering is shifting from coding to product engineering, focusing on solving user needs rather than writing code. Advances in AI and abstraction tools enable more people to build and use software without deep technical knowledge. (newsletter.chainofthought.show)
JetBrains developed a RAG pipeline called Air Context to improve semantic code search, enabling LLM agents to find precise, evidence-based code snippets from repositories. Semantic search allows agents to understand code meaning beyond keyword matching, increasing efficiency in large codebases. (blog.jetbrains.com)
