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.

Charge Robotics | Multiple Roles | Full-time | Onsite | SF Bay Area

Hi HN! We’re a YC-backed, Series-A startup building robots that build large-scale solar farms.

Check out a video of our first system here! https://youtu.be/ZZ2fP1Y5Z2E

It turns out that construction companies literally can't build solar fast enough, so what we're doing is a crucial part of switching the grid over to renewable generation.

You’ll be a key contributor, helping bring our next generation of mobile solar factory to life.

Come work with us if you love:

* Fast-paced prototype development with software and hardware components

* Making a positive climate impact through your work

* Hacking on massive construction equipment!

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.

Hatchet | Full-Stack Engineer | NYC or SF or REMOTE (US and EU) | https://hatchet.run

Hey HN! I'm Alexander, one of the founders of Hatchet. Hatchet is an open-source platform for running background jobs at scale.

We're hiring engineers who are excited to build the next class of engineering primitives, starting with queues, background tasks and durable execution. We started in early 2024 after launching our distributed task queue (https://news.ycombinator.com/item?id=39643136).

Hatchet is currently used by thousands of engineers for all kinds of workloads: log ingestion pipelines, code review agents, video encoding, GPU scheduling, etc. Our target customer is fast-growing startups who have a strong need for background jobs system. 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.

Note that we're fully open-source, which you can check out here: https://github.com/hatchet-dev/hatchet (and if you have thoughts / opinions / questions about the codebase, please include those in your note!)

Long Tail | full stack | REMOTE/US Based | full time

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.

Neo.Tax | Senior Full-Stack Engineer & Senior Data Scientist/ML Engineer | REMOTE (US, Pacific hours) | Full-time | $190K–$210K + equity Neo.Tax automates R&D tax credits and software cost capitalization for enterprises. We ingest data from project management, payroll, identity, and financial systems and use ML/LLMs to turn a process that used to take months into one that takes hours. Small team, real revenue, lots of hard problems in data extraction and pipelines at scale. Currently serving customers like Mercury, Brex, Notion, Adobe, and Capital One.

We're hiring two senior roles:

1) Senior Full-Stack Software Engineer (7+ yrs) TypeScript/Node + React on the front of the house; data ingestion pipelines processing millions of records and flexible schemas across wildly different company types on the back. You'll own projects end-to-end, scope with cross-functional partners, and ship both customer-facing and internal tooling. Bonus: GraphQL, GCP/AWS/Azure, Terraform/DevOps.

2) Senior Data Scientist + ML Engineer (6+ yrs) Own ML/AI problems from definition through production: classification, information extraction, entity resolution, ranking, anomaly detection, plus LLM systems (prompts, retrieval, tool-calling, eval). Python (NumPy/Pandas/sklearn/PyTorch), strong SQL, and real production deployment experience. Bonus: synthetic data, RAG, experience fine-tuning LLMs.

Both are senior, high-autonomy roles--you should be comfortable breaking ambiguous requirements into iterative deliverables and reading unfamiliar code. Not a fit if you want heavy mentorship or detailed specs handed to you.

Strobe Power | Founding Engineer | ONSITE (Brooklyn or SF) | https://strobepower.com

AI data centers are creating a massive new wave of electricity demand, and the grid is already stretched. Strobe is building an autonomous power company to help meet that demand: software that turns buildings, batteries, EVs, and generators into a distributed power plant that can buy, sell, and dispatch electricity in real time.

We’re a 6-person, well-funded team backed by top investors. This is early, high-ownership, and very real-world: the software you build will control physical assets and move money in energy markets. We are the only company actively trading distributed power in New York - the space is entirely new and unlocked by recent FERC regulation.

I’m looking for a staff engineer to own the data integrations and cloud infrastructure that make the whole system work. That means connecting to utilities, grid operators, OEM hardware, weather providers, and our optimization engine — then making sure it all runs reliably when market events are happening and dollars are on the line.

You’d work on things like:

* Wholesale market integrations with NYISO, CAISO, ERCOT: pricing, capacity markets, dispatch signals * OEM hardware integrations for monitoring, control, and telemetry * Utility data pipelines, including Green Button Connect / ESPI, interval usage, billing, and meter data from utilities like ConEd, PG&E, and SCE * Weather forecast pipelines feeding our scheduling engine * Event-driven AWS infrastructure using Lambda, API Gateway, AppSync/GraphQL, EventBridge, IoT Core, Timestream, Amplify, and CloudWatch * Terraform IaC, observability, alerting, and the reliability work needed when downtime has real financial consequences

Good fit if you have deep AWS experience, have used Terraform seriously in production, and write a lot of Python. Energy experience is a plus, but not required. Experience with utilities, government APIs, OEMs, hardware, telemetry, or other “real world is messy” systems is very relevant.

Stack: Python, TypeScript, Rust, Terraform, AWS, GraphQL/AppSync, MQTT, Grafana. We use an AI-agent-optimized monorepo and are investing heavily in agent-enabled engineering efficiency.

Small team, no layers, high trust.
