VLM Run is building infrastructure for production Vision-Language Model (VLM) systems — fast inference, tool-use + orchestration, reliable structured outputs, and the observability to iterate quickly. We’re a deeply technical team of veteran AI / computer-vision engineers (20+ years combined, MIT/CMU PhDs) who’ve shipped production ML infrastructure across autonomous driving and LLMs.
Open roles:
1. Infrastructure Engineer (Full-time, ONSITE): $150K–$220K + 1–3% equity https://app.dover.com/apply/VLM%20Run/8d4fa3b1-5b38-42e1-927...
2. AI/ML Engineer (Full-time, ONSITE): $150K–$220K + 0.5–3% equity https://app.dover.com/apply/VLM%20Run/1a490851-1ea1-4f12-a0f...

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.
The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.
We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.
We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.
Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.
We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

Looking for experienced engineers to build and scale infrastructure and data platforms for a Berlin asset management fund. We are betting big on AI to drive investment returns and build the best infrastructure to support our high alpha targets (track record >30% p.a. since inception; https://bitcap.com/en/bit-global-technology-opportunities-ai...).
You'll design large-scale data pipelines, evolve our lakehouse architecture, strengthen data quality and observability, and build infrastructure for AI/LLM workflows (agentic scaffolding, RAG, LLMOps, AI for engineering). We are looking for a hands-on technical leader, that is steering initiatives end-to-end while staying deep in implementation.
We have our roots in tech entrepreneurship (Jan Beckers), and this mindset still dominates our work culture, even as a regulated financial institution. We are a team of ~40 with a flat hierarchy, hands-on leadership, fast-paced decisions, and a little nerdy culture as people are actually passionate about their work. Stack: AWS, Databricks/Spark, Python, PostgreSQL, Agentic AI.
If the complexity of financial markets excites you as much as the complexity of distributed systems, you'll love it here. Competitive comp, relocation & visa support, stellar team.
Conductor is an app that lets you run a team of coding agents on your Mac. We've grown 10x since January, and just yesterday we announced our $22m Series A. We're a small team (four people) and we're looking for exceptional software engineers and designers to work with us in SF!
We're reimagining mortgage underwriting for a world where engineers and operators are supercharged by modern AI. We work with 8 of the top 20 mortgage lenders in the country and we're just getting started.
AI transforming knowledge work isn't inevitable. It takes smart, resourceful people who can go beyond pure engineering to understand real problems and build product experiences that bridge the gap between cutting-edge tools and the workflows people actually use.
We're specifically looking for a strong frontend engineer who thrives at the intersection of product, design, and customer feedback, someone who can move fast, iterate independently, and make the right tradeoffs between different competing needs.

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.
