Looking for my Shel Kaphan | Dirac | Lead Founding Engineer | 5% equity + £70k base (£100k base after series A) | London, Acton | in-person only
Dirac is building the next Walmart-sized retail company over 10+ years. We sell d2c and are doing £300k-£500k monthly sales (lots of toys and reasonably seasonal). I built most the initial systems which run the company’s backend (purchasing, databases, pipelines etc.) but we will need something (and someone!) better to reach £1bn+ sales over the next four years
We need to go from a bunch of bash scripts coordinated by systemd, adhoc estimators and pipelines to a more coherent machine for demand estimation, matching products, warehousing and purchasing.
You’ll be mostly writing code (django+postgre+a hetzner server) but also helping our two more junior devs.
The vision for the company is twofold: (1) find 1000s of suppliers and wholesalers worldwide and (2) to ingest all their pricing, logistics and then move stock to where prices and demand is highest.
Visa sponsorship possible.
Investors include will thorndike, charlie songhurst, patio11, backedvc and some others!

FinQuery | AI Engineer | REMOTE (US) or Atlanta, GA | Full-time
I'm hiring an AI/ML engineer to join the AI/ML team at FinQuery.
Our team creates services powered by LLMs and traditional ML to enable features across our suite of products. Like many companies, we are trying to separate the real value of the latest AI techniques and tools from the hype (agents?), and unlocking use cases that actually benefit our customers. This role is a rather generalist role for someone with a strong ML background, 2+ years of work experience (post schooling), and a desire to work on both proof of concept and production systems. You would be joining our small AI/ML team as we continue to automate as much as possible and enable new product features and use cases.
FinQuery makes software to help companies comply with new lease accounting regulations, manage financial contracts, and keep track of recurring and one-off payments. We're based in Atlanta, but support fully remote employees in the US. This is an IC role.
We are also hiring for roles in DevOps, marketing, and more.
Riza | San Francisco | Full-Time | System, Backend, and Full-Stack Engineers | https://riza.io
We provide isolated runtimes for executing untrusted code, mostly generated by LLMs. Our sandboxing is powered by a combination of WebAssembly, V8, and microVMs. Our customers do things like extract data from log lines at run time by asking claude-3-7-sonnet to generate a parsing function on-the-fly and then sending it to us for execution.
Things we need help with:
- Our API (https://docs.riza.io/) (Postgres / Go)
- Our account dashboard (Postgres / Go / React / TypeScript)
- Our code execution engine (Go / Rust)
- New products including code generation workflows (Anthropic / OpenAI experience a plus)
We’ve raised seed money, but the whole company is currently just me, Andrew and David working out of a converted warehouse on Alabama St. We’re second-time founders, so we know the risk we’re asking you to take and we’re prepared to compensate accordingly.
See open roles and apply here: https://jobs.ashbyhq.com/riza

AO Labs | real-time reinforcement learning | https://www.aolabs.ai/ | SF, CA + remote
AO Labs is an applied AI research lab building real-time reinforcement learning, unlocking AI that can be hyper-personalized with less data than LLMs.
Our first product is an API that learns by combining end-user context, application data, and a feedback signal (eg. an end-users' likes and dislikes) in a fast learning loop that's lightweight enough to provision a distinct agent per-user. There's no gap between training and inference-- train at the edge, learn all the time.
With our framework we increase training efficiency and also combine the static pre-trained intelligence from LLMs with continuous training to learn local contexts. AI progress is bottlenecked by backpropagation, which necessitates labelled data to set the ground truth while also leaving a gap between training and inference that result in increasingly larger, more homogenizing models.
We are hiring for applied researchers & various engineering roles– please reach out to [email protected]

To make that work well, we want to hire an open source engineer who can manage contributions, create training materials, do refactoring, manage forums, and do all the other things necessary to nurture a healthy open source community.
Particularly interested in people with experience maintaining Open Source projects and working with outside contributors.

Rock Rabbit | Backend Engineer | Full-time | USA FULLY REMOTE
Buildings account for ~40% of all emissions. There is a ton of federal, state, and local programs to help decarbonize buildings -- but this money is difficult to access, trapped behind complicated program requirements, uncertain eligibility, lack of clarity, and long payout cycles. We make access to these incentives easy by abstracting away the policy complexity and letting our users focus on their projects. Our platform serves contractors, homeowners, incentive providers and implementers, and equipment manufacturers.
We're hiring Backend Engineers for full time roles.
We're well-funded, have a lot of customer traction, and are rapidly expanding the team. Our product vision is very clear -- the bottleneck is skillful, user-focused execution.
Tech stack: Python (FastAPI, pyright), Google Cloud (GKE), React (Typescript, react-query, auto-gen API client)
We value curiosity, ownership and collaboration. Interest in energy, climate, and sustainability is a plus.

Layer | Full stack & Backend Engineering | San Francisco | https://layerfi.com
We believe SMBs are the backbone of American society and small business ownership is the best path to wealth creation and economic mobility for many Americans. We're trying to dramatically lower the activation energy in just one of the major hurdles for aspiring small business owners: accounting and bookkeeping.
Our approach is working! We embed directly within an SMB's primary business platform, manage all the data syncing & reconciliation for them, and have real humans (with real AI tooling) handling their books. We do this at ~half the cost of existing bookkeeping services and it's still profitable for us because we're saving so much time with our data access + AI.
Adoption is taking off faster even faster than we hoped and we need to grow the team! We're a team of 5 who like working with a high ownership and high throughput collaboration. We have serious technical challenges across scaling systems, data modeling, and building AI-driven automations of tedious tasks.
Our hiring philosophy is simple.
1. The early engineering team isn't just building products, it's setting the culture, practices, and standards for the whole org. Find teammates who have the appetite and agency to go beyond excellent code.
2. No one knows more than 10% of what they need to be successful at an early stage startup. Find teammates with the highest trajectory of learning and growth and give them as much opportunity and responsibility as they want.
3. We talk to real small businesses with real problems every single day. Find teammates who want to win by making our customers successful day in and day out.
