Mulligan Post, Inc - On-Site near Millbrae BART/CalTrain Station in Burlingame - $60-120/hour Contract - Mechanical Design Engineer / Mechatronics / Industrial Automation.

Software hacker seeking hardware hacker to make custom robots for Magic: The Gathering automated storage and retrieval system to power an online e-commerce store (think CardKingdom competitor or eventual TCGPlayer competitor.) In terms of scale, the eventual target is >100k different _skus_, million items in inventory, tens of thousands picks per day. The industry is large; eBay bought TCGPlayer for $300M about 3 years ago.

I am looking for a mechanical/electrical/hardware generalist to complement my software expertise. Someone who knows how to integrate off the shelf parts into custom automation to solve problems. If fast iterations, direct connection with the project in use, autonomy and minimal bullshit overhead appeals to you then this could be a great fit. You are: someone who makes stuff and solves problems, is a clear communicator and fast study. You know how to challenge a requirement, source an off-the-shelf-part or design custom manufacturable part and when to do each. I don't really care where or when or what your degree is in if you have demonstrated driving things to completion and we vibe well enough.

We will use OnShape (license/seat will be provided) for collaboration and document management reasons. Much of what we need to build is integrating FUYU linear rails, Clearpath motors, pneumatics with some custom Send Cut Send / Xometry parts, 8020 frames, etc.

Pros: Small team / minimal overhead and wide scope. Clear guidance on what to build. Flexible-ish schedule (core hours 9-5 in office, flexibility for school breaks, etc.) Real problem with established market.

While I'm primarily looking for a contractor for now, I am open to the possibility of bringing the right person on full-time with equity if they are interested and invested in the space, but that is not a requirement and it probably makes sense to establish that after working together for a bit.

No recruiters or third parties, not able to sponsor at this time. Compensation dependent on experience.

Hiring process: resume/project review, vc chat < 1 hour, then paid 1-day work trial where we see if we fit.

BuildBetter | Senior Engineer (Backend, Full-stack) | Full-Time | Remote (US) | 170-200k base + equity | Visa Sponsorship not provided

BuildBetter is the product operations platform for customer-led teams. We've built an AI-first product that lets our customers, like Rappi, n8n, Posthog, and Brex automate the operations work that lets them provide their customers with world-class product experiences.

We're looking for two senior engineers to join the team; our headcount has remained small while growing revenue, and we're now bottlenecked by development speed in a way that will make you invaluable. You'll have real ownership over your code from product ideation to customer support, and we'll be making substantive product updates weekly. We're looking for team players who are as fun to work with as they are productive, and are willing to compensate these two rolls commensurately - our aim is to be in the 95th percentile of equity compensation, and we expect that in exchange we'll have value-aligned employees who will help us grow the business.

Joining us will mean solving hard problems at the frontier of AI adoption, including:

- maintaining performance at scale

- building and maintaining rich frontend user experiences that maintain the standards of usability and delight that our customers know us for.

- building agent and workflow systems that automate real work for customers

- playing around with the latest models to figure out new experiences that we can offer our customers as cutting-edge models get released monthly

- building automation that's grounded in supporting product teams rather than automating them - our bet is that this is the likelier outcome out of the current generation of AI systems

Stack: Postgres / TS (Nest + React) / Hasura / EKS / S3 / LLM APIs / Python

Benefits:

- unlimited PTO

- $100/mo education stipend

- flexible hours: we measure productivity in terms of outcomes, not time, so as long as you're able to stay aligned, productive, and in regular communication, we don't really care what hours you work

- health insurance

Part of the process includes a practical take-home assignment (real-world, not leetcode), followed by technical conversations with engineering leadership.

We’re looking for someone who can think in systems, make good architectural decisions, and operate with a high level of ownership.
