We are a people-first, boutique tech agency creating on-demand teams and software solutions for long-standing clients. These clients trust us to practice engineering excellence as though we were members of their own staff. Our leadership team is ex-Fortune 100 with software engineering backgrounds: we’re still coding. Notable recent projects include a gigantic ERP migration for Anduril Industries, and a skunkworks with Surge Labs helping to develop some of the frontier LLM models themselves (yes, seriously). This is a remote-first agency, but some projects involve onsite work.
I’m the founder and CEO, and I’m trying to do what I call “enlightened business”.

In return you’ll get:
* Flexibility and a low-bureaucracy environment * Clients that won’t treat the vendor like “the B Team” * The chance to act as a code architect, not just implement tickets * Exposure to a wide variety of industries and modern challenges * Me as your personal champion and advocate Feel free to submit, even if you already did in the past.We’re currently especially seeking:
Back-end, Front-end, and Full-Stack Software Engineers, Tiers 3 and 4 (Typescript/Javascript, React, NextJS; Ruby on Rails; Python; DevOps, and third-party API integrations)

Tier 4 roles are 11-20 years experience, $215-$260K total comp.
Higher tiers exist, and we always welcome exceptional applications.
Though not yet universal, many of our clients are now demanding senior/staff engineers with success using modern agentic approaches. Be ready to explain where current models work well and where they do not.
Please apply using this Google Form: https://forms.gle/Ec9WgTTakAV8HcAx9

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 just recently announced our $42M Series B! 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! We’re hiring various mid-level, senior-level and staff-level engineers. Engineers own projects end-to-end so full stack ability is expected.
Check out our open roles here: https://shepherdinsurance.com/careers
* In the form, be sure to mention that you heard about this opportunity via Hacker News.
Our stack includes: Typescript, React, Next.js, GraphQL w/ Apollo, Node.js, Postgres & Redis
We’re hiring for: Full Stack, Backend, AI Engineer, ML Engineer
– If you have experience building AI agents or multi-step reasoning systems, we’d love to hear from you.
