Cloudflare | Senior Systems Engineers – Basin (Pipelines, SQL, Catalog) | Austin, TX / Seattle, WA / London, UK | ONSITE | Full-time | $185k–$254k + equity (US range, varies by location)

  Last week we announced the General Availability of Basin (https://blog.cloudflare.com/cloudflare-basin/), a serverless data platform built on Apache Iceberg and R2. It has three parts:
  Pipelines (streaming ingestion and SQL transforms), Catalog (a managed Iceberg REST catalog with table maintenance) and SQL (a distributed query engine).

  We also launched K2 (https://blog.cloudflare.com/cloudflare-k2-streams/), a durable event stream built on R2 that started out as the ingestion buffer behind Pipelines.

  We're hiring for two roles:

  Basin Pipelines: work on the streaming engine (built on Arroyo) and K2. You need experience writing the core of a storage or streaming system, and strong Rust or C++.
  https://job-boards.greenhouse.io/cloudflare/jobs/7093840

  Basin SQL and Basin Catalog: work on the query engine (Rust, DataFusion, Arrow, Parquet) and the Iceberg catalog. You need 6+ years in distributed systems. Experience with Rust and query or storage
  engines is a plus. https://job-boards.greenhouse.io/cloudflare/jobs/8030240

  Apply through the links, or email me at yevgen at cloudflare dot com with "HN" in the subject.

RealResponse | Product Engineer | REMOTE (US) | Full-time | https://www.realresponse.com

We build software used across college athletics, professional sports, higher education, and other organizations, from reporting and compliance to live event operations. We're a team of < 15 people, with no venture capital, and profitable. This means we get to make decisions for our customers and our team, not for investors. Rails is at the core of everything we build, and we keep reasonable hours and a codebase we're proud of.

We're looking for someone who solves problems across the board: building and improving our applications, shaping products, internal tools, fast prototypes, and the systems that keep quality and security high. You'd own problems end to end, from understanding what the customer actually needs to shipping the fix.

On the AI side, we want someone who knows how to:

- Evaluate new models as they ship, and pick the right one for the job (fast and cheap vs. most capable)

- Design agents and multi-agent workflows with tool use, and know when a simpler approach is better

- Build retrieval that stays accurate as the underlying content changes (RAG, embeddings, search)

- Measure quality with evals and observability, so changes are proven rather than guessed

- Keep AI features fast, reliable, and cost-effective under real production load

- Handle AI security properly: prompt injection, data isolation between customers, and sensitive data

Stack today: Rails 8, Hotwire, Hotwire Native, Postgres, AWS. Rails experience helps but isn't required. What matters more is a strong grasp of solid engineering practices and principles, and the judgment to use the right tools to solve the problem.

To apply: email jobs@realresponse.com with subject "Product Engineer: [your name]". Include a link to something you built, a few sentences about a problem you solved end to end, your salary expectations, and your CV.

Pairio (https://pairio.app) | Senior Swift Engineer | REMOTE (Europe) | 32-40h/week | Employee or freelance | $65k-$85k + equity

Pairio is a native macOS app for real-time screen sharing, built for people who work together. You share your screen, your teammate draws on it and takes over your keyboard. One click to call, no link, no invite. We use it every day to build it.

You'd work on pixel-perfect screen sharing (capture, encode, transport, rendering), one-click calling (WebRTC), drawing and remote control, privacy (app masking, encryption) and latency. The Swift app talks to a Rails backend, so bonus points if you're comfortable on both sides.

We're looking for deep native macOS or iOS experience in Swift, a real feel for UX and pixel-perfect UI, and someone who enjoys owning large parts of a product in a small team. Please be based in Europe so we have real overlap for pairing.

We're four founders in Amsterdam running a healthy, profitable business. Stack: Swift, SwiftUI, AppKit, Rails. Flexible start.

Email us a bit about yourself, what you've built and why this interests you: hello@pairio.app, or see https://pairio.app/jobs
