Hey HN, I'm hiring engineers for the new Cloudflare Data Platform (https://blog.cloudflare.com/cloudflare-data-platform). We do streaming ingest and processing, managed Iceberg catalogs, and a distributed query engine—all built on R2 and the Cloudflare Edge. We're making it ridiculously easy for Cloudflare customers to build data lakes.
I'm looking for Rust engineers with experience working on databases, stream processing engines, and query engines. You'll get to work on incredibly cool tech on a huge scale.
Note: we are hiring for on-site roles in one of our engineering hubs, not hiring remote at this time.
If you're interested, shoot me an email (in profile) with subject HN and a brief description of your background and interest in the role.
Chestnut builds software insurance carriers actually run their business on. We replace legacy, manual distribution systems with real-time data, automated workflows, and AI-driven tooling in a space that hasn’t changed much in decades.
This is product engineering. We ship to real customers, operate what we build, and spend time fixing the sharp edges that show up in production.
You’d work on backend-heavy product features around onboarding, compliance, payouts, and integrations. A representative problem: building a commission payout flow that ingests messy carrier data, applies complex rules and hierarchies, explains results to ops, and executes payouts that must reconcile cleanly with finance—while handling holds, chargebacks, retries, and partial failures.
Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS, LLM tooling.
Roles:
- Senior Software Engineer – Product / Backend (https://jobs.ashbyhq.com/Chestnut/fbbb7601-3d31-48b4-8639-75...)
- Staff Software Engineer – Architecture & Scale (https://jobs.ashbyhq.com/Chestnut/f28c5ee5-12aa-4e7b-b0ea-f5...)
- Engineer – Agent Orchestration & Workflow Systems (https://jobs.ashbyhq.com/Chestnut/075a0010-bfa5-489e-8808-e9...)
Hybrid in SF and Seattle.

Duranta | Staff Frontend Engineer | On-site, Seattle or NYC | Full-Time
Duranta is making a "business-in-a-box" SaaS for landscaping companies. We have a rather neat offline-first mobile application and a webapp. We also have a custom AI visual model to do estimations based on the satellite imagery (we're not shelling out to OpenAI/Gemini/...). Our stack is Go+Postgres on the backend, a bit of Python, and React/React.Native on the frontend.
Website: https://getduranta.com/ Jobs: https://jobs.lever.co/getduranta/c416cd42-3709-4de0-91ae-385... and https://jobs.lever.co/getduranta/50af551a-9a5c-498c-9729-6f2... You can apply there or by emailing me at alex@getduranta.com (add HN in the topic).
I’m hiring for some (IMHO) really fun product manager roles on Cloudflare’s Developer Platform (workers.cloudflare.com) - Workers Runtime - Set vision for our V8 isolate based runtime that lets people deploy JS, TS, Rust and Python to the globe in seconds with great dev ex. - Containers - Help build our new containers platform into the best place for both agent Sandboxes and stateless global apps. - AI Agents - Define what Agents on Cloudflare look like: from our AgentsSDK, to Sandboxes, to MCP Servers, “Code Mode” (see our blog) and more.
We’re a really technical group, and tend to like product managers that can straddle the line between engineer and PM. You should be able to set high-level vision, understand architectural constraints, and be technical enough to really deeply understand our users (developers).
