FurtherAI | San Francisco | Onsite | Full-time | https://furtherai.com

We're building the AI agents that run insurance - a $1T+ industry still run on PDFs, email, and manual review. Our agents read the documents, pull from the systems underwriters already use, and actually complete the work. In production at top-10 carriers and F100 brokers; ~10x growth in the last year; backed by a16z and YC.

The hard problems: keeping an agent reliable across dozens of tool calls; orchestration + evals + reliability on top of frontier models.

We've rebuilt the product from scratch more than once as the models got better!

Stack: Python, TypeScript/React, Azure, frontier LLMs.

Roles (all onsite SF): - Staff AI Engineer — agent reliability, evals, orchestration ($250–350K + equity) - Staff Product Engineer — full-stack, own the product surface ($250–350K + equity) - Staff Infrastructure Engineer — Azure, single-tenant, SOC 2 ($250–350K + equity) - Founding Product Manager — technical, first PM ($180–230K + equity)

MixRank (YC S11) | Software Engineers | 100% Remote (Global) | Full-Time MixRank processes petabytes of data every month through web crawling. Hundreds of customers use our data products, including Google, Amazon, Facebook, Intel, and Adobe, across industries such as finance, recruiting, sales, marketing, and security. We’re a fully remote company with a global footprint across 20+ countries. We’re growing, profitable, employee-owned, and have no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.

We’re looking for passionate individuals for whom programming is not just a job, but something they genuinely love to do. We’re obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.

Our codebase is friendly to new contributors. You’ll have a fully functional development environment within hours through full automation and will be pushing commits on your first day. Deployments to production happen multiple times per day and finish in under two minutes.Effectively all of our codebase is written in Python, Rust, SQL, JavaScript/TypeScript, and Nix. The core technologies you’ll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.

We operate at a larger scale than typical startups. We run two datacenters with high-performance servers we’ve built ourselves, capable of handling the volumes of data we process. We’ve implemented our own distributed file system, perform full-scale web crawls, and download and run static analysis on the entire universe of published Android APKs and iOS IPAs.

Unlike a typical startup where you might spend half your time in meetings and the other half fixing Jira tickets, at MixRank you’ll challenge yourself with difficult technical problems that help you grow as an individual. We’re continuously hiring for the positions below; these aren’t singular roles that close once filled. Our philosophy is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities around their interests. Other companies may create a long list of specific requirements with the expectation that you’ll exactly replace someone on the team or fit a role defined by committee. MixRank is more pragmatic: we first get excited about bringing a unique individual onto the team, then figure out the best way to support their specific talents.

Distru (https://www.distru.com) | Senior Software Engineer | AI Product Engineer | Senior Product Manager | REMOTE (Americas & Europe) | Full-Time

Distru is the #1 ERP in the cannabis industry. $3.5B in annual GMV flows through our platform, and most of the top cannabis brands and distributors in the US run their entire operation on us to stay compliant.

We're profitable, stable, and growing. No runway anxiety, and we're reinvesting into new product lines. We're an intrinsically motivated team that works without ego, is constantly learning, and genuinely cares about our people (5/5 on Glassdoor).

Distru is at an inflection point. We have deep market penetration in cannabis ERP, a new commerce layer (Distru Commerce, a B2B wholesale marketplace) live and growing, and a roadmap with a growing AI component. Our live AI Order Agent already lets buyers submit orders in any format from any source, killing manual data entry, the first of many bets on using AI to strip the repetitive heavy lifting out of running an ERP.

The roles: You'll own mission-critical parts of the product end to end, from planning and design through implementation, testing, and shipping. You might work on AI-native features (order/purchase intake, smart product matching, systems that learn from user feedback), Distru Commerce storefronts and ordering, manufacturing and distribution workflows, cultivation mobile tools for the floor, or compliance integrations with state systems like Metrc. These are high-ownership roles: you'll partner directly with product, design, support, and our C-suite, and you'll get customers writing you personal "thank you" emails.

Stack: React + TypeScript, Elixir/Phoenix + GraphQL, PostgreSQL, React Native, LangGraph

Stripe | Hybrid (50% of time in Toronto office) | Senior Go developer

We're looking for a senior-level Go developer who can design and ship idiomatic code our users love to work with. We can all write Go that compiles, but don't always know what best practices for 3rd party code are (in the Go ecosystem specifically). Ideal candidates are a part of the Go community / ecosystem and know what the current best practices are. They also probably have TypeScript experience (most of our tooling is TS) and in a perfect world, Ruby/PHP ecosystem knowledge (the other languages we're currently seeking expertise in). But, if we get a Go expert who's willing to learn a bunch of TypeScript, that probably works!

JD and application: https://stripe.com/careers/listing/backend-engineer-develope...

The best way to apply is to go through the form on the site. Happy to answer questions here though! It's a fairly unique role.

Vitalize | Full-time Engineer | San Francisco (hybrid)

What we do: Hospitals run critical operations (staffing, labor planning, and capacity) on spreadsheets, phone calls, and gut instinct. Labor is the biggest cost and hardest operational problem, and it’s still largely manual. Vitalize is building the operating system for hospital labor (and ultimately capacity): we forecast demand from real hospital data (e.g., ADT + historical patterns + acuity) and translate that into concrete staffing decisions: next month’s schedule and the next shift.

Traction: - Launched Jan 2024; ~$8M committed ARR across 10+ health systems (deals ~$300K–$2M) - Live in 20+ hospitals and growing quickly - ~$37M raised (Oak HC/FT, Norwest, .406, plus customer-investors MemorialCare & Rochester Regional Health)

How we work: We’re extremely customer-obsessed: everyone visits customer sites (including engineering) and we regularly build alongside operators to solve real problems (not hypotheticals). High ownership, high candor, high velocity.

Who we're looking for: Engineers who learn quickly, reason clearly about hard problems, and want to ship high-impact product at the intersection of AI + operations + healthcare. If you're interested, email me mark@vitalize.care

Stack: TypeScript + Postgres + Effect

Comp: $160k–$270k + equity

Ashby | YC 19 | REMOTE | Hiring Engineering Leaders | $200k–$275k Ashby is the all-in-one recruiting platform powering hiring at the world's most innovative companies. If you cmd+f "Ashby" you'll see that we're powering many of the job postings in this thread!

We’re looking to scale our engineering leadership team with technical leaders who want to raise the impact of a high-performing organization.

* Not Your Traditional "Jira-Manager": Our EMs are not classic delivery coordinators who shuffle meetings or build heavy processes. Instead, you will own people, hiring bar, technical judgment, and the health of our engineering systems.

* High-Autonomy Team: Because 80%+ of our engineering team is Senior–Staff+ level, our engineers already possess a high degree of ownership. Your focus is less on day-to-day task coordination and more on coaching independent owners, managing ambiguity, and raising team impact.

* Technically Credible Leaders: You will stay close enough to the work to challenge assumptions, review proposals, spot maintainability issues, and jump into the code to debug alongside engineers when needed.

* Organizational Advocates: Beyond your immediate team, you will act as an advocate owning the health and metrics of org-wide areas—ranging from CI/CD health and developer productivity to customer success collaboration and on-call sustainability.

* 100% Remote Async Culture: We maintain an even distribution of engineers across North America and Europe, optimizing for minimal process and maximum focus.

* Here's how we're thinking about AI at Ashby:https://www.ashbyhq.com/blog/engineering/ai-ashby-engineerin...

* Full transparency on engineering levels + comp:https://www.ashbyhq.com/blog/engineering/leveling-and-compen...

Stack: TypeScript (frontend & backend), React, GraphQL API, Node.js, Postgres, Redis. (While you won't always be shipping code, you are expected to hold a deep technical understanding of the system).
