Ask HN: Who is hiring? (November 2025)

Joby | Bay Area | Full-Time

Imagine a piloted air taxi that takes off vertically, then quietly carries you and your fellow passengers over the congested city streets below, enabling you to spend more time with the people and places that matter most.

We are looking for an experienced and motivated Mobile/Full stack Senior Software to join our Air Taxi Systems team.

Most of our apps are built with SwiftUI, TCA, and GraphQL. Our backend is a mix of Java, Rust, and Swift using Federated GraphQL.

We are also hiring a variety of engineers, technicians, and corporate roles: https://www.jobyaviation.com/careers/

EQTY Lab | Software Engineers (Fullstack / AI ), or DevRel | SF, LA (looking for local, but wfh if cool) | Full Time | https://www.eqtylab.io/

We are hiring software engineer(s) to help innovate on applied agentic applications and governance/alignment at runtime.

Specifically, you will help us release and further enhance https://github.com/eqtylab/cupcake - a solution derived from our Claude Code feature request for hooks. We believe hooking into the agent harnesses will be critical for scaled adoption; ambitions for purely LLM-driven trusted behavior exist today- but we must empower those responsible for run-time with deterministic guarantees. We do so by hooking into the harnesses - Claude Code, and now supported by Cursor, soon Gemini CLI. Beyond coding agents, we look to apply this to web harness agents, whether it's LangChain, Google ADK, etc.

We are looking for an engineer, or devrel equiv, that can:

  - help develop across the full stack from an integration perspective (build the supporting bindings and SDK abstractions for web-based frameworks)

  - create quality demonstrations/tutorials/advocacy

  - continue to advance on the forefront of agentic security as well as better performance for agents.

Synthropic | Detection Engineer + GenAI | Full-time / Part-time | Remote (SF) We're an early-stage startup looking for someone passionate about detection engineering and generative AI.

If you know SIEM, threat intel, logs, detection modeling/strategy, purple teaming, and adversary emulation — and you've been wanting to explore how LLMs/agents can accelerate detection engineering workflows — we'd love to talk.

The role A lot of it is what we call AI babysitting: guiding 1,000 kindergarteners (LLMs) as they try to become senior detection engineers. Sometimes they're brilliant, sometimes chaotic — your job is to shape that into something production-ready.

You'll be part detection engineer, part researcher, part builder, with a big say in shaping the product and how AI gets applied to real-world problems.

Ascento | Zurich, Switzerland | Full Stack | https://www.ascento.ai

Ascento develops autonomous security robots that patrol outdoor areas to detect and report. All in support of security guards. We stay away from conflict, just robots driving circles around buildings in remote boring places. The technical challenges however, are far from boring.

We are looking for a full stack engineer to join as a core member of the off-robot software team. This is the software that plans, configures, operates and creates insights from data collected from the robots. You would work across the whole cloud-stack, consisting of Frontend (React), Backend (Typescript / Go), Infra (Terraform / AWS / GCP).

The cloud software team is still small, meaning you get a chance to help set priorities, guide long-term architectural direction and figure out how to best help our users. We celebrate pragmatism, we work hard to make simple systems and we help each other to hyperfocus.

Sounds like the place for you? Drop an email to [email protected]. I'm curious to read what about this ad caught your interest.

Think of us as a cross between Github and Palantir, with an opportunity to significantly impact a $10 trillion industry. Our platform already powers workflows on billion dollar projects at leading firms like Suffolk, Multiconsult, Pomerleau, and Stantec.

I'm the CEO/founder and I can honestly vouch that we're tight knit team that values autonomy and shipping cool product on top of our data layer (me included - and this might be a red flag for some, but it's my therapy) over hierarchy, politics, levels and complexity (my spirit animal is the grug brained developer). We love working together with our customers - construction is truly a unique place where each project is its own micro universe.

We have multiple roles open across engineering and growth (sales & marketing) [1]

Lantern | NYC only, hybrid 4 days a week in office | Senior Software Engineer (mid career - Staff)

Lantern is Series A company, building the future of sales automation with AI agents that actually work. We're replacing the messy patchwork of enrichment tools, intent platforms, and automation software with a single system that does it all—pulling from 150+ data sources to research prospects, verify contacts, and help close deals.

On any given day, you might:

- Build reliable agentic workflows that orchestrate multi-step research and outreach processes

- Architect systems that scale gracefully as we handle increasingly complex prospect analysis and verification

- Collaborate directly with early customers to understand how our AI agents can solve their hardest go-to-market challenges

Tools we use:

This is a chance to work on genuinely novel problems in AI—not just fine-tuning LLMs, but building autonomous agents that can navigate messy real-world data and make smart decisions. If you're excited about pushing the boundaries of what AI agents can do in production, we'd love to talk.
