## Job description

## About HASH

At HASH, we're building infrastructure to [solve information failure](https://hash.ai/about/mission) and help everybody make the right decisions. Our open-source platform helps firms integrate both structured and unstructured information into knowledge graphs that support simulating, optimizing and automating processes.

We’re building towards world models from a radically different perspective to most AI labs. Our founders include Joel Spolsky (former founder of Stack Overflow; acq. $1.8bn, and Trello; acq. $425m), Jude Allred (former CTO of Glitch) and Dei Vilkinsons (former CEO of Soho Strategy).

## About the role

In the last 6 months we've seen significant growth and are now scaling fast. We're hiring Forward-Deployed Engineers in London to help build real-world applications for our customers utilizing HASH's technology.

This is a highly technical, customer-facing role for someone who enjoys operating at the intersection of AI, systems thinking, and problem-solving. You’ll work closely with customers to understand their goals, translate complex business problems into robust technical solutions, and help them realize value quickly.

## Requirements

- Strong technical ability, with experience shipping software, or building AI systems in production: prior AI/ML engineering, data engineering, applied AI, or product engineering experience is a hard requirement — specifically you'll require expert (Staff+) level knowledge of TypeScript
- Ability to work directly with customers and own complex problem-solving end to end: you'll interface with external stakeholders and will need to draw upon social intelligence, business context, and technical insight in your work — demonstrating clear, structured communication.
- Strong judgment, high agency, and a bias toward execution: comfort operating in fast-moving environments with a high degree of ambiguity
- Genuine interest in helping customers succeed, not just shipping technology: results-oriented and impact-motivated; many of our engagements are priced based on the results we deliver, as is compensation in this role.

## What you'll do

In essence, you'll talk to customers, act as a technical architect, and write code / develop solutions yourself (both solo and within a wider team):

- Partner with customers to understand their workflows, data, and operational challenges
- Design and build AI-powered solutions using HASH, especially for enterprise use cases
- Translate ambiguous business problems into structured technical plans and deployable systems
- Work across knowledge graphs, structured and unstructured data, LLM-based workflows, and automation
- Lead technical discovery, solution design, implementation, and rollout with customer stakeholders
- Act as a trusted advisor to customer teams, from operators and technical teams through to executives
- Work closely with product, engineering, and research to shape the platform based on real customer needs
- Help define repeatable solution patterns, delivery playbooks, and best practices as we scale

## Why HASH

- Work on first-principles AI research tied to a large and important real-world mission
- Join at a moment of rapid growth, with outsized scope and influence
- Help build a leading frontier AI lab in Europe with global ambition
- Work alongside founders who have previously built and exited businesses worth billions of dollars
- Be part of a team that moves fast, is enthusiastically open source, and is in it for the long-term

## Benefits

Our team have founded and sold billion-euro companies from scratch. We offer leading equity-weighted total compensation, including competitive salaries and tax-advantaged options.

We meet together quarterly in-person for whole-team retreats, provide engineers with generous learning and tech budgets, and recognize and reward output.

This role is primarily performance-incentivized and pays £90,000-£140,000 base/bonus, plus meaningful equity.

## About HASH

## Company Overview
- **One-liner**: HASH is an open-source platform for decision-making that integrates live data, constructs ontologies, and creates shared understanding through collaborative agent-based simulation and knowledge modeling tools.
- **Entity Type**: Private (Seed stage)
- **Headquarters**: London, United Kingdom
- **Founded**: 2019
- **Founders**: Joel Spolsky and Jude Allred

## Core Business
- Primary industry/industries: Technology, Information and Internet; Business Decision-making Software; Simulation & Modeling
- Target customers: B2B, Enterprise (with a focus on safety-critical supply chain, biopharmaceutical logistics, and complex systems modeling)
- Mission or purpose statement: "Eliminate information failure and help everybody make the right decisions."

## Products & Services
- **[HASH Platform (hash.ai/hash.dev)]**: An open-source, collaborative workspace for structured knowledge that integrates live data, enables ontology construction, and provides fast, distributed agent-based simulation. Combines knowledge capture and modeling tools for complex systems decision-making.
- **Block Protocol (blockprotocol.org)**: An open standard they drive for interoperable, data-driven blocks, contributing to the commons.
- **Open Source Simulation Engine**: Built in Rust/WASM, focused on agent-based simulation and formal verification of distributed systems.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metrics**: Annual Revenue of approximately $1 million; Total Funding of $2.5 million (1 seed round)
- **Notable Investors/Partners**: Zetta Venture Partners (Lead), Root Ventures, with 6 total investors in the seed round. They also work with the Advanced Research + Invention Agency (ARIA) and scientists from the University of Oxford.
- **Growth Signals**: Headcount grew 14.3% YoY (now 9 employees); actively recruiting for new engineering and research roles; conducting high-profile research programs with ARIA and Oxford on safety-critical supply chains; 2,460 LinkedIn followers with 15.6% yearly growth; employer rating of 5.0/5.0 on Wellfound.

## Competitive Advantages
- **Unique Open-Source Approach**: All core tools are open source, building trust and allowing external validation—rare in the decision-modeling space.
- **Technical Moat**: Combines graph-backed world models, formal verification, and agent-based simulation (Rust/WASM) with AI research. Very few companies operate at this specific intersection.
- **High-Impact Focus**: Working on genuinely hard problems (eliminating information failure) with safety-critical applications (supply chains, biopharma logistics), giving them a defensible niche.
- **Elite Talent Sourcing**: Proactively identify and hire exceptional people through their own tooling and community, not just open applications.

## Strategic Focus
- Current priorities: Building a next-generation platform for decision-making via graph-backed world models and AI; expanding into safety-critical supply chain management with government and research partners; advancing their open standard (Block Protocol).
- Direction for growth: Scaling the engineering team (Rust, TypeScript, Python), deepening AI research (graph learning, formal verification), and expanding use cases in complex systems simulation.

## Why Work Here
- **Culture & Work Style**: "We care about output, ownership, and quality." They value raw intelligence, high-energy, and standout performance. The team works in public, contributing heavily to open source.
- **In-Person Focus**: Operates in-person from offices in **London** (HQ) and **Berlin**, with company-wide get-togethers at least twice a year in Europe. Some remote flexibility is available (e.g., Full-Stack Engineer roles can be in-office or remote).
- **Compensation & Perks**: "Leading compensation" with meaningful equity, competitive salaries, an 'unlimited' equipment and learning allowance, and at least 30 days paid time-off each year.
- **Engineering Culture**: Work on hard problems in Rust, TypeScript, and Python, including formal verification, graph learning, and simulation. They emphasize a fast, conviction-based hiring process with decisions made "within days, not weeks."
- **Hiring Process**: A short introductory call followed by a focused work sample or technical deep-dive. Most hires begin with HASH reaching out, but candidates can apply for specific roles.
