Purple Dot | 1x Senior Full Stack Engineer (London, UK) + 1x Customer Solutions Engineer (New York, US) | 2 days/week in office | Full-time

At Purple Dot, we are on a mission to create a world where, ultimately, every product that is manufactured is sold. The current e-commerce model leaves brands waiting for stock to arrive at the warehouse before they can start selling, leading to missed sales opportunities, unsold inventory and waste. We believe the next wave of innovation will happen in the time before stock arrives, enabling brands to sell inventory no matter where it is in the world. Our pre-commerce platform puts the power back in brands’ hands, allowing them to take control of their sales timelines and maximise revenue potential.

And we make pre-orders trust worthy for the shoppers too, keeping their money in escrow until items ship, and always up to date on where their pre-order is at, with an option to cancel no questions asked.

We've raised a $10m Series A in 2024, we've plenty of runway left and we're looking for help as we scale our platform through the next order of magnitude in terms of load on the system and ultimately the number of dollars we process.

We are a team of 22 split evenly between the UK and US. 32% female, including the CEO. All of us have a mix of startup and big tech experience. For the founding team this is our second (so far :) successful startup.

I have two engineering roles open:

* senior full stack engineer - based in London, UK - to join our core engineering team of 6 that are shipping our product roadmap: https://purpledot.notion.site/senior-full-stack-engineer-uk

* customer solutions engineer - based in New York, US - to work with our support and sales teams to help make going live with and using Purple Dot a delightful experience for brands and their shoppers: https://purpledot.notion.site/customer-solutions-engineer-us...

Like everything else we do, we interview fast, and you will deal with me (head of engineering) throughout.

Iterum | ONSITE/HYBRID (London, UK) | Full time | https://iterum.uk

Iterum is a seed-stage startup revolutionising appliance management for scaled residential properties. Our platform, Iterum IQ, is addressing a critical but overlooked challenge in property management: the inefficient handling of home appliances and consequential lack of actionable data. These things together lead to significant costs, wasted time, and increased carbon emissions. Our mission is to streamline appliance procurement and management, delivering substantial cost savings for property operators and investors, enhancing resident experiences, and reducing carbon footprints at scale.

We’re looking for a talented and ambitious mid level (at least 3-5 years experience) full stack developer to join as our Engineering Lead. You’d work with me - the (fractional) CTO - as well as the (full time) Head of Product and the rest of the team to get Iterum IQ from MVP to scale.

Our tech stack is Django with SSR, PostgreSQL, Bootstrap, HTMX, and a couple of other tools and services. You should be familiar with Django and strong on the backend side, at least competent on the (web) frontend side and with (cloud, at this point) infrastructure management. We’re a small team, so you’d work on pretty much everything.

You’d need to already be based in or near London. The job is onsite, though hybrid is fine.

If you’re interested, please apply here: https://uk.indeed.com/job/engineering-lead-e99f1366ca04fc52

We do what we can to ensure our process is swift and respectful of your time.

RevEng.AI | London, UK | Full-Time | https://reveng.ai/about#jobs

We're a seed stage startup having raised $4.25m from top tier VCs across the US and Europe. You’ll play a key role in advancing our platform pushing the boundaries of AI-driven program analysis.

We're looking to hire a team of Frontend, Backend, and Full Stack Engineers. Our tech stack currently uses react, fastapi, redis, celery, rabbitmq, and k8s.

* 5+ years of experience * Hybrid working environment but ideally commutable to London, UK * Solid understanding of software engineering design * Ability to thrive in a fast-paced start-up environment * Prior experience working with vector databases or complex data

To apply or learn more, email contact[at]reveng.ai with "hn" in the subject line.

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).

Visa sponsorship possible.

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.

https://finquery.com/careers/

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.
