We're building the operational memory and state management layer for production AI agents — persistent execution history, shared state, and ACL-gated memory so agents get more reliable over time without constant human intervention.
Well funded and assembling the founding team. This is the beginning.
We're hiring for:
- Founding Engineer: https://jobs.ashbyhq.com/mubit/77a5ea32-5012-4073-b9a8-c5364...
We're turning compliance from a bottleneck into a creative advantage for regulated brands. Clients include Monzo, Lloyds, PensionBee, and Plum. Raised £2.6m+ from Outward VC in our first 14 months.
The problem: we run multi-agent AI pipelines that evaluate regulated marketing content in real time. The model landscape moves fast and our architecture has to move with it. You'd own how these systems evolve in production, working directly with the CTO and AI engineers, while also shipping across the full stack.
Stack: TypeScript, React, React Router v7, Tailwind, shadcn/ui | Hono on Cloudflare Workers, Drizzle ORM, PostgreSQL (Neon) | Python, FastAPI, LangChain + LangGraph | GitHub Actions
We're 6 engineers. You'd have real input into architecture, tooling, and how the team operates. We use Cursor, Claude Code and Greptile day-to-day.
£75-95k + equity. Private healthcare, gym budget, hardware budget.

Bogotá, Colombia:
* Senior Software Engineer II, Guides & Surveys - $90~93k USD + up to 10% bonus - https://www.fullstory.com/careers/jobs/073bfc41-0ac6-4e59-a5...

For US roles, you can expect regular raises & bonuses, equity, and benefits including: health insurance, 401k matching (Vanguard), annual learning stipend, unlimited PTO, parental leave, and more. I take about 4-5 weeks vacation a year, in addition to ~3 weeks worth of company holidays (federal holidays + the week of Christmas to New Years.)
Folks in other countries can also expect a strong benefits package, but I'm not as versed on the details.
Additionally, you get a 5-week sabbatical after 5 years of employment - I took mine about a year ago, and it was fantastic.

We are MiLaboratories, the team behind Platforma.bio & MiXCR. We are building the "OS for Biology"—the foundational infrastructure where all biological data is transformed into life-saving breakthroughs. We work fully on-site in Bilbao because the complexity of our problems (high-performance computing + deep biological nuances) requires high-bandwidth, in-person collaboration.
We dissolved traditional departmental silos. We are hiring hardcore builders, not analysts, for a critical core role:
*Senior TypeScript (SDK & Platform):* You will architect our frictionless, AI-native SDK to scale our ecosystem. This is not a CRUD web dashboard. You will build a heavy local desktop application that bridges directly with a high-performance Rust data layer. You must treat the browser engine as a runtime for heavy local apps. The standard is simple: if the SDK is too messy for us to build blocks at AI-speed, it is too messy for the world.
The Offer: * Comp: Top-tier EU salaries (€90k - €120k EUR). * Tax Advantage: Bizkaia has independent tax autonomy. You qualify for the "Special Impatriate Regime" (30% salary tax exemption + expense deductions - up to 50% in total). * The Reality: Your effective tax rate drops to ~15-20%, yielding a significantly higher net income than London or Berlin. * Stock: We grant ESOP and treat equity as a life-changing wealth vehicle, not a "nice to have." * Relocation: Comprehensive "Soft Landing" package (Visa, temporary housing, school search). * Location: Bilbao is a hidden gem—ocean, mountains, and high quality of life with a low cost of living.
Process: No HR screening. You will talk directly to the engineering team.

We build an AI system that builds software for complex construction & infrastructure megaprojects to sell things currently only sold by service providers. To do this, we both do whatever it takes to solve complex projects' needs AND build the system that automates ourselves out of it. We just raised our seed round (25m$ valuation) and currently have 4 people, looking to hire 6-10 total this year.
== Platform Engineer Build the system that takes our jobs. Algorithms, infrastructure, shared components, agents, and internal tooling - across the full stack. Our platform engineers build everything from our custom meeting integration to AI coding agent harnesses, sandbox environments, complex shared app features and more.
== Customer Delivery Lead / Forward Deployed Engineer Help build the AI systems that run megaprojects. We’re looking for a customer-obsessed generalist who can understand complex problems and ship solutions - part product designer, part delivery lead, part AI wrangler. In this role you deploy with customers, build software that solves their problems and do whatever it takes to maximally learn about the way they run their complex projects.

We’re Quadrature, a technology company in the algo trading space. We use advanced machine learning on large amounts of data to predict trends in financial markets. More at https://quadrature.ai.
What makes us different:
- ~250 people, no traders — our systems trade autonomously.
- Single PnL.
- We don’t separate “quant researchers” from “developers” — everyone codes to a high level and has the opportunity to do research.
- Mission-driven: our climate foundation (https://www.qc.foundation/) has made significant divestment commitments over recent years. For many of us, it's why we're here.
We’re hiring Quant Developers — a generalist team of engineers and researchers who own both the research pipeline and software infrastructure across the entire business. Stack is Rust, Python and C++. We want sharp, collaborative people with no big egos.

Alterdd is building the fit intelligence layer for fashion. Currently, brands lack structured data on how their products actually fit real customers, making it a massively costly problem. We are fixing this by helping brands understand their fit so they can sell clothes that fit correctly the first time.
We are looking for our first technical hire to take full ownership of our engineering, moving our technology from prototype to production.
Why this role is interesting:
This is specifically designed as a bridge for a hungry Senior Engineer who is ready to step up into a Lead role. If you want the autonomy to build both the product and underlying systems from the ground up without waiting for direction, this is your shot to earn that Lead title. You will work directly with the founder with zero layers between idea and execution.
What you will do & stack:
- Design and build scalable systems across frontend, backend, and data layers. - Stack: Full-stack applications using TypeScript, React, Node, Python (or similar). - Data: PostgreSQL , building pipelines to ingest product feeds and fit data. - Integrations: Embedding our tech into e-commerce platforms like Shopify. You will need to design systems that handle highly inconsistent product and sizing data across different brands.
Working style & Interview: Hybrid working (2-3 days a week in person) in London or Cambridge. The interview process is fast and respects your time: one online technical interview, followed by one in-person interview with the founder.
To apply, please reach out to tech[dot]jobs[at]alterdd.com
