Ask HN: Who is hiring? (October 2026)

Sidekick Labs | Senior SWE, R&D Engineer, Intelligence Engineer | REMOTE (US Timezones) | Full-time | $170k to $230k Base + Equity + Health

Sidekick builds AI security software for enterprises. Our sensors observe AI behavior and use in situ. From those observations, our reasoning pipeline produces an application inventory and a risk picture, allowing us to provide real-time intervention and coaching right when it matters.

Compensation: base salary scaled to experience, meaningful early-stage equity, and 100% covered health insurance for you and your immediate family

We are a highly senior team. Most of us have been founders or on early founding teams, so we operate with high ownership. We expect you to have a real, current AI-assisted development practice. Our system spans several languages, and we expect you to use AI tools to quickly navigate unfamiliar parts of the codebase so you can comfortably own problems end-to-end across a broad stack.

We are hiring for three roles:

- Senior Software Engineer: You will work across our event-driven architecture. You'll write Go and Python backend services and touch endpoint-deployed browser and desktop components. You need to be comfortable developing in a multi-tenant, microservice-driven SaaS architecture and understand typical scale and security implications for such products.

- R&D Engineer: This is not an open-ended research function. You will take ambiguous feasibility questions tied to our roadmap and return defensible answers inside a week. You'll build handoff-ready prototypes, then shift into engineering mode to personally drive them through to production. You will also define operational envelopes and degradation boundaries, and rigorously deprecate infeasible ideas with documented rationale to avoid future re-litigation.

- Intelligence and Data Processing Engineer: This role is for someone who loves real browser and desktop forensics. You'll use dev tools and debuggers as your primary instruments. Expect to be reading minified code to find where state lives and analyzing network logs to understand undocumented APIs. You will figure out how AI products work and build the prototyping and automation to maintain our software inventory.

To apply: Send an email to [email protected] with the role in the subject. Include a PDF of your resume, a quick sentence or two about a tough technical problem you've solved recently, and links to your GitHub, personal site, and/or LinkedIn.

I'm Eric, VP of Technology, and I will personally read every email sent to the HN subaddress. You can view my background here: https://www.linkedin.com/in/three-two-one

Fazeshift | Senior Software Engineer | San Francisco, CA | ONSITE (5 days/week) | Full-time | $200k–$235k + equity

I’m Chris, VP Engineering at Fazeshift. We’re nine engineers plus our Founder/CTO and me, and I’m hiring someone who can help us do more, better: increase both what we can build and the quality and sophistication of the software we build.

Accounts receivable sounds boring until you look under the hood. It sits at the intersection of money, business relationships, software systems of various vintages, and a huge amount of repetitive human work. Instead of giving finance teams another dashboard to stare at, we’re building AI agents that actually do the work across billing, collections, payments, cash application, and the systems connecting them. We’ve grown revenue 12x since 2024, and eight unicorns now run AR on Fazeshift.

A big part of what makes the engineering interesting is that we’re intentionally not the system of record. Our customers already run on ERPs, CRMs, banks, billing systems, payment processors, spreadsheets, and internal software, so we have to understand state across systems we don’t control, act safely in them, and recover when reality disagrees with what an API says should have happened. A timeout doesn’t necessarily mean a write failed. Webhooks can arrive late or twice. A payment may not contain enough information to identify an invoice. In those cases, blindly retrying can be exactly the wrong thing to do.

We use coding agents heavily ourselves. Engineers use Conductor, stacked PRs, Linear, and multiple frontier models every day, with internal skills and tooling that let agents drive and validate our local development environment. We’re especially interested in engineers whose development workflow has already materially changed because of coding agents: people who are comfortable delegating meaningful work, keeping independent threads moving in parallel, debugging where agents get stuck, and improving the surrounding system when the workflow breaks down. But generated code is still your code. Judgment, debugging, systems thinking, taste, and understanding what actually shipped matter more here, not less.

Our development style is roughly: design enough to find the shape of the problem, then build to learn. There’s a short distance here between noticing a problem, deciding what should happen, building it, and seeing the result in production with our customers. You’ll own meaningful problems from ambiguity through design, implementation, rollout, and production, and you’ll work directly with the people affected by what you build.

We’re looking for 5+ years of professional experience, strong TypeScript/full-stack skills, solid systems judgment, and real production ownership. No fintech background needed. Stack: TypeScript/Next.js, tRPC, Prisma/MySQL/PlanetScale, Inngest, AWS.

I read every HN application myself. Email [email protected] with HN in the subject, your LinkedIn/GitHub/résumé, and a few sentences about something interesting you’ve built or improved recently.

there used to be 800+ posts here :(

This role always shows up here. There's no way you're not finding anyone to fill this?

Had a very poor experience with this company, was contacted for an interview and one hour before the meeting was contacted by the HR asking to reschedule. We rescheduled and the day of the call I was there waiting like a retard, I emailed the HR to understand what was going on and nobody ever answered. Just be careful when applying to this company
