Coop (https://smart.coop.farm)| 2nd Founding Engineer | iOS Heavy Engineer | Hybrid onsite | Austin, TX | Full-time, Part-time

My name is AJ Forsythe and I'm the Founder / Chief Chicken Tender at Coop! We're an Austin TX based company on a mission to build the world’s largest decentralized food production network, starting with AI powered chicken Coops. We’ve been in the market for about 18 months and our customers are in 48 states and will generate about >10M eggs this year. It's insanely fun to work on and we have a shot at building a huge business in the connected urban farming space. If you’re big into computer vision, consumer products that are fun, and an awesome team we would love to chat. The Coop has an automatic door + cameras doing computer vision work (predator detection, egg alerts, remote health monitoring, etc). It's a super exciting time and are seeing directional product market fit which I'm thrilled about. Seriously go check out our website, it's a super fun + amazing product.

We’re a tight-knit team of 5 people with 15+ years of experience working together. We’ve been through YC, started and scaled multinational million-dollar businesses together, taking them from idea to acquisition by a Fortune 50 company. We’re gritty and passionate without taking ourselves too seriously - and we’re here to build something really exciting that helps people reconnect with their food and the planet. We're VC backed (call it $5M) by some of the world's best investors but we are a scrappy small team that moves fast. We have an absolutely fantastic CTO Ryan that I'm looking for his / our right hand person to work alongside with. I think the term full stack is overused but that's closest to what we're looking for. Also this really isn’t a traditional Eng role, I look at it as we’re a small growing team and you would be one of us working on a ton a cool projects on day 1. Also, we LOVE working with founders so if you've started a company before that's epic.

Oh also, I have a fun project where I want to make a water gun turret that uses our cameras to detect predators and allows you to aim and blast them. If you're into hacking robotics and gimbals etc, please reach out.

You can also reach out to me directly at: aj[at]coop.farm - Just email me your LinkedIn / GitHub / portfolio + why you think you'll be an awesome fit and I'll respond. Please don’t use GPT too much. This is my 3rd company (2 have exited) and I want to build the super solid core team and you might be the perfect fit for us and vice versa. Bwok Bwok! AJ

Mission: Build better culture & growth systems for companies that don’t have them. Then make them stick.

Role: Somewhere between product, customer success, and HR consulting. You won’t “manage HR internally.” You will operate as an embedded advisor across multiple companies, helping them design, run, and improve their people programs using our platform and AI tooling.

Company: We’re a SaaS company in the employee engagement space. Our customers are Heads of People, HRBPs, and founders who want to run better 360 reviews, engagement surveys, and feedback systems-but don’t have the time or expertise to do it properly. FeedbackPulse makes employee engagement simple with tools for creating meaningful surveys, gathering staff feedback, and building a better workplace culture. Our platform offers engagement surveys, performance reviews, and 360° feedback solutions that help companies address high turnover rates and disengaged workforces.

You: HR/PeopleOps experience, using AI tools like Claude Cowork daily, clear writing skills, self-directed, and results-oriented.

Our culture: Direct communication, focused deep work, clear work-life boundaries, and sustainable growth as a bootstrapped company.

Mention you are from HN in your application message.

Maiven is hiring software engineers. We are looking for highly skilled builders. While all roles require strong full-stack capabilities, one of these roles will lean heavily into data engineering infrastructure, and your experience should set you up to hit the ground sprinting.

The reality: we operate as an intense, early stage startup. Our 50+ hour work weeks are baseline. If you want a comfortable gig, this isn't it. If you have high agency, want massive ownership, and genuinely love the chaotic highs and lows of building from scratch, let's talk.

Reddit (YC 1) | reddit.com | Staff MLE | Full-Time | Remote (US) (ideally east coast) | $230K - $322K base + equity

We are looking for a staff MLE to join the Ads Content Understanding team. This team looks at all of the reddit content in order to understand what people are talking about. We own the knowledge graph for the entire company, and we also produce a number of interpretable signals that are then used either for RAG type products or as features for models. This is a horizontal/platform team, all of our customers are internal, and most of them are within the ads space, but we're doing some interesting things with organic shopping experiences on reddit.

There's a lot of upside to this role, we're still nascent on our 'commercial intent' understanding (think - is this post comparing tokyo vs kyoto, or is this post at a later stage in the trip planning journey, it is comparing hotels in kyoto).

The job posting does a solid job of describing the responsibilities and expectations for this role. It's a mix of modeling, engineering, leadership. Please apply if you think there's a good fit, the ideal candidate has both leadership experience as well as domain experience with content understanding.

Team is roughly split into two pods, knowledge graph (mostly EU eng) and signals (mostly US eng). This would be a TL role for the signals pod, so east coast timezone would have the most overlap with our team and partner teams.

We also have an open Senior MLE headcount for this signals pod, and are expecting more headcount in Q3.

These days, that tends to be AI companies, though we're general-purpose and not exclusively targeted for AI workloads.

Stack: Postgres, Go, Typescript, React, Kubernetes

Applying: email me at alexander@hatchet.run and tell me about something impressive you've built, along with your CV and why you're interested in Hatchet.

We build software to help hospitals fight insurance companies.

Small team that just took investment from PE firm so we're scaling rapidly. Looking for AWS-native full stack architects with 5-10 years' experience. No healthcare background required (always a plus though).

Psiphon | iOS / Flutter Developer | Toronto (Hybrid) | Full-time

Psiphon is a VPN app used by millions of people to access the open internet in regions where it's restricted. Small team, software that matters.

We're building the next-gen client app in Flutter (iOS, Android, macOS, Windows) and need someone who can work across both iOS native and Flutter. Split is roughly 65% Flutter, 35% iOS native (Swift, StoreKit, entitlements, network extensions). You'll have mentorship from a senior iOS specialist for the deeper networking work.

Day to day: Feature development in Flutter, iOS platform integration (subscriptions, permissions, App Store), and occasionally going deep into network extensions and packet tunnel providers. Small team (~3-4 core devs), high ownership, low ceremony.

Looking for: Strong Swift experience beyond just UIKit/SwiftUI app dev, comfort with the iOS ecosystem (App Store process, provisioning, StoreKit), and willingness to context-switch between Swift and Dart in the same day. Flutter experience is a strong plus but not required if you pick up frameworks quickly.

Contact: hr@psiphon.ca

Forward Deployed Engineer - backend - python | REMOTE (UTC -3 to +3) | Full time

Small stealth team in the property management space, building AI agents that run real operations, where agents and humans work as one team rather than as user and tool. Funded, profitable, fully remote, competitive comp.

We want a senior backend engineer to own a client facing use case end to end: build the backend tools and workflows our agents call, handle the jurisdiction and client specific extensions, and talk to the client directly. Pull requirements, explain the tradeoffs, own the relationship. Take messy real world problems, turn them into something agents can actually use, then keep it alive in production.

You're probably a fit if:

- you've shipped serious backend systems in production

- you can hold your own on a customer call

- you've run LLM agents in production, or you'll ramp fast: tool calling, evals, knowing when a plain deterministic tool beats a model call

Bonus, not required: containers and CI/CD, RBAC and auditing, LangChain and LangGraph, prior customer facing or operator background.

We care more about what you've built and can build than a checklist, so skip the skills inventory and tell us about something hard you shipped.

Apply: email mercedes@kinxshn.com with "HN - Forward Deployed Engineer" in the subject , your CV attached and salary expectation.
