8X Energy | AI / Machine Learning Lead (fast track to CTO) | Frederick MD or Remote | Equity

We are building the AI-powered energy decision infrastructure SaaS for the commercial energy transition. USPTO non-provisional patent pending on the core methodology. Live pilot project underway at a Maryland nonprofit technology incubator.

The company is pre-investment. We are in active seed raise discussions and have enterprise pilot confirmations from Pharmaceutical, Electric Companies, National Energy trading platforms, and federal agencies.

What we need: An AI and machine learning lead who has shipped production SaaS before. Not a researcher. Not a consultant. Someone who has taken software from prototype to deployed, maintained it in production, and knows what breaks when real users engage. You should be comfortable with the full stack from model development through deployment and understand what it means to build AI systems that need to be auditable, accurate, and defensible in a regulated environment. Energy domain experience is a plus but not required. The ability to learn a domain fast is required.

Specific experience we are looking for: You have built and deployed at least one production AI or ML system that real customers use today. You have legacy software development capability meaning you can work in an existing codebase, not just greenfield. You understand the difference between a model that performs well in testing and a system that works reliably in production. You have led or been a senior contributor on a SaaS product from architecture through deployment. You are comfortable working with a non-technical founder CEO and translating business requirements into technical specifications without waiting for someone to tell you exactly what to build.

The role: You would be leading the AI and machine learning layer across three energy specific products, working directly with the CEO and the existing development team. The fast track to CTO is real. We need a technical leader, who may be an individual contributor today, and the equity structure reflects that.

Compensation: Pre-investment: equity only, 3.5% to 7.5% depending on experience and contribution level, with vesting on a standard 4-year schedule with a 1-year cliff. Post-investment: market-rate salary plus retained equity. We are not asking you to work for free indefinitely. We are asking you to believe in the upside long enough to get to the raise, which is actively in process.

Location: Frederick, Maryland preferred. Remote for the right person. T o apply or learn more: Email [email protected] with a brief description of the production AI system you are most proud of shipping and why. No recruiters.

Tenki Cloud by Luxor Tech | San Francisco, CA | Founding Sales | Full-time | SF-based preferred | https://tenki.cloud/

We're building Tenki, Luxor's compute platform for developers and AI agents: faster, cheaper GitHub Actions runners, code-review agents, and isolated sandboxes where agents run code. Next up: agent workflows and CPU/GPU compute.

Tenki was built by the founding team behind Luxor Technology, a leading provider of Bitcoin mining and AI infrastructure. Teams like Anchor, Omnara, and Naive already rely on it, and MAU has grown ~3.5x since April. We're building the infrastructure layer for the next generation of AI companies, and we want Tenki to be the go-to platform for AI teams worldwide. Now we need someone to sell it.

You've sold technical products to technical buyers and can talk CI pipelines and infra costs without hiding behind a sales engineer. Dev tools or cloud infra experience is a big plus.

What you'll do: - Own the full cycle, from prospecting to close to expansion - Turn self-serve signups into revenue - Work closely with engineering and product, and bring customer feedback into the roadmap - Build the playbook from scratch - Show up at SF meetups, hackathons, and dev events

You'd be the first sales hire on a small, technical team. No playbook yet, full ownership.

ALBERT | REMOTE ALMOST ANYWHERE IN THE WORLD| Hiring principal and distinguished engineers to build net new products | up to ~ $750k Hiring: exceptional consumer product engineers at Albert.

We're a consumer fintech with 20M+ users who trust us to budget, save, invest, and bank in one place. Profitable for 4+ years. And as of today, our average employee tenure is 3.6 years, a number you almost never see in startup tech, and one we're quietly proud of. People stay because the work is good, the people are sharp, and we've built something worth staying for.

Now we're building net-new consumer products from zero, and we're looking for people who love to tinker and build stuff to ship them with us.

The kind of person we're looking for: • Top fraction of a percentile in craft, the kind of good that's hard to fake • Builds for fun, not just for work. The kind who ships a working prototype over the weekend and can't help themselves • Comfortable owning 0 to 1 consumer products end-to-end • Allergic to politics, theater, and bureaucracy

What you get: • Remote, anywhere with reasonable timezone overlap (and for someone truly exceptional, we'll make async work) • Real scale from day one (20M+ users, real money, real consequences) • Compensation that beats the market. We pay well and we mean it. Base, discretionary year-end bonus, meaningful 401(k) match, and meaningful equity in a profitable, growing unicorn (the kind that's actually worth something) • Platinum PPO health benefits with Blue Shield, top of the top of the line, covering your entire family • A mission worth your time: make money simple, so people spend less time managing it and keep more of it • Small senior-heavy teams, direct ownership, no layers • Forthcoming with the business metrics that matter, so you always know how the company is actually doing • The startup perks done right: catered lunches, wellness stipend, team offsites, casual dress. The stuff that compounds when you're showing up engaged for years, not months • Profitable for 4+ years, so you build with conviction, not runway anxiety

Stack: python, claude, postgres, react.js /react native

If this is you, email us at [email protected]

Also, we carefully review every application. If we think there may be a fit, we'll reach out within a few business days. Either way, thank you for your interest in what we're building and for taking the time to connect with us.
