San Francisco Jobs - August 2026

Joulent | Founding ML Platform Engineer, Energy Intelligence | San Francisco | HYBRID | Full-time | equity

We deliver multi-gigawatt power to AI data centers, and this is the founding hire on the team that forecasts load and market prices. You own the whole spine: ISO/RTO market feeds, weather and plant telemetry through feature store, serving, drift detection and the model gateway.

Not a scale problem — the data is rich, not petabyte. Feeds land late and get revised after the fact without ever throwing an error, so the failure mode is a price series quietly wrong for three weeks behind a forecast that looks fine. The work is trust infrastructure: lineage, freshness SLAs, point-in-time correctness, eval gates that can block a model.

Python, SQL, Airflow, containers, IaC. 5+ years on production data and ML platforms; energy background welcome, not required.

Canopy | Staff Software Engineer, Sensing | SF Bay Area (Peninsula) | HYBRID | Full-time | $200-225K + equity | https://canopyworks.com

Canopy builds the real-time coordination layer for hospitals: communication, safety, location intelligence, and response across large, complex care environments. Every hospital is a logistics problem wrapped around a clinical one, with millions of people and events an hour across the country. When a building can sense itself in real time, the gap between an event and the right person arriving goes from minutes to seconds. People are safer, care arrives faster, and hospitals and clinics get a path to modernize on the infrastructure they already run. Sensing is the foundation.

You'd build our next-generation sensing and ML pipeline (the "physical full stack"), from sensors and embedded firmware through edge algorithms to the backend and frontend services. Physics-based modeling for sensing problems that traditional IoT products can't solve, in devices that have to survive harsh environments. We care deeply about hardware-in-the-loop platforms, simulations, and internal tools. Ideal candidates have shipped production features on both sides of the hardware/software line.

What we've deployed recently: TypeScript, WASM, Rust, C, Python, RTOS (Zephyr, FreeRTOS), embedded Linux.

If you care about the difference between 99.99% and 99.999%, and about the frontline medical staff relying on that last nine, you'll like it here.

Apply: https://job-boards.greenhouse.io/canopyworks/jobs/4317128009 AND email hn <at> (company domain) about a real-world sensor that broke your prior assumptions: what you expected, what the data actually did, and what you changed.

exe.dev | SF Bay Area | full time | $200k+, meaningful equity

Come build a new cloud. The entire engineering team has been in the industry 20+ years. Lots of hard problems. The freedom and responsibility to do what you think matters, push it to prod and deal with support when it breaks.

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.

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)

Tasklet | Head of Design Engineering, Software Engineer (multiple), Customer Success Engineer | San Francisco, CA | ONSITE | Full-time

Tasklet is building the AI platform companies use to run their business on agents. You describe an outcome in plain English and our agents do the work across your SaaS tools, APIs, browser, files, and internal systems — immediately, or in the cloud 24x7 on a schedule or in response to events. Every agent gets its own cloud computer, filesystem, database, and browser. We're a team of 12 in SF, founded by Andrew Lee (Firebase founder) and Jonny Dimond, backed by $42M from USV, Lightspeed, YC, and others.

Head of Design Engineering ($300–450K base, 0.35–0.70%) — IC role owning our product experience end to end: decide how Tasklet should work, design our UX, and personally ship it in production. Looking for an experienced ex-founder builder with exceptional taste and real design & frontend chops.

Software Engineer — multiple roles ($220–400K base, 0.15–0.60%) — agent harness, context management, sandboxed execution, model serving, storage, Kubernetes, mobile & web apps. Deep systems fundamentals matter more to us than an AI résumé. Mid-level through Staff+.

Customer Success Engineer ($130–180K base, 0.05–0.15%) — own customer relationships & support our users. Help our customers use Tasklet more effectively and feed what you learn back into your core offering. We're looking for an AI power-user who's great with customers. ~1–5 years professional experience. No engineering background required.

All roles are in person at our office in SF -- no exceptions -- and we're not sponsoring visas at this time.

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

Shepherd (Series B) | ONSITE | San Francisco, CA & New York City, NY

At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered.

The infrastructure behind the AI boom (data centers, semiconductor fabs, renewable energy assets) has to be built and insured, but traditional carriers weren't built for this speed. We built Shepherd to solve that.

We announced our $42M Series B earlier this year! That brings our total funding to over $60M — led by Intact Private Capital, the investment arm of one of the largest insurers in the world. Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building.

We’re looking for product-minded, high ownership engineers to join our team! The Engineering team is HQ’d in SF, but we’re growing in NYC now too!

We’re hiring for 2 Senior and 1 Staff SWE in SF, and 2 Staff SWE in NYC. Engineers own projects end-to-end so full stack ability is expected.

Check out our open roles here: https://shepherdinsurance.com/careers

Our stack includes: Typescript, React, Next.js, GraphQL w/ Apollo, Node.js, Postgres & Redis

– If you have experience building AI agents or multi-step reasoning systems, we’d love to hear from you.

* In the form, be sure to mention that you heard about this opportunity via Hacker News.
