## Job description

## About HASH

HASH provides an open-source platform which helps firms integrate both structured and unstructured information into knowledge graphs that support simulating, optimizing and automating processes. Our [mission](https://hash.ai/about/mission) is to solve information failure, and help everybody make the right decisions. To that end, we're unapologetically excited. Actions speak louder than words, and we measure performance by output. We prioritize speed, and measure product delivery timelines in hours and days, not months and years. We value high-energy, high-expectations people who do what they say and say what they mean. We're committed to building a high-commitment, high-trust environment, and believe that the best teams are most productive together, in-person.

## About the role

HASH is growing rapidly, doubling its headcount and expanding its client-facing business. As our Founder's Associate you will work directly alongside HASH's founder/CEO to effectively manage and further accelerate this growth.

Your role will be split between three main areas:

- Making the company run like clockwork. Initially that means creating processes and executing them yourself. As we grow it means delegating those processes to others and building various operational functions: PeopleOps, FinancialOps, SalesOps, etc -- and you should find the idea of ensuring operational excellence stimulating.
- Leading the delivery of special projects. You'll be asked to run key, strategic initiatives that are new to the company, and we're tackling for the first time (or on a one-off basis). For example, organizing a high-profile event, coordinating a product launch, or expanding into a new market. Analytical, project management, and people skills are all equally important in this role.
- Ad-hoc founder support: support the firm's founders on time-critical matters, and experience what it takes to scale a company on a daily basis. This role is full-time, in-person, working in HASH's London office.

## Requirements

You should have completed (or be about to complete) a Bachelor's or Master's degree (by summer 2026 latest) from a top university in Business, Management, Software Engineering, Maths, or a similar field.

- Outstanding verbal and written English: Fluency in English is required for this role (C2), along with a natural talent for writing well, effectively and persuasively.
- Attention-to-detail: Strength in following complex multi-step instructions, incisively identify key information, and spot discrepancies.
- Responsiveness and proactivity: Default to quick replies, and comprehensive follow-ups, supporting effective collaboration with busy senior stakeholders.
- Strong sense of ownership: Attracted to responsibility, you do what it takes to execute when expectations are set.
- Resiliency and grit: Determination to work hard in the face of uncertainty and setbacks without giving up.
- Numeracy: Ability to read and process financial statements.
- High raw IQ: Capacity to problem solve and reason well across a wide range of domains and problem areas.
- High social IQ: The sensibility to manage diverse stakeholders, implicitly detect tone and feeling, etc.
- High social energy: The drive and motivation to pick up the phone whenever required to unblock things, even in the face of frustration.

Candidates must also be excited about the prospect of working at a fast-growing startup with a high-performance culture, and have realistic expectations as to what this entails.

Over time you may choose to specialize in an area of the business you find most interesting, or continue in a generalist role.

## Benefits

This role is heavily performance (tax-advantaged options) incentivized, atop a base salary of £70,000-100,000. In addition, you'll receive 30 days flexible paid time off each year.

HASH's founders have previously sold companies for tens of millions, hundreds of millions (Trello; $425m) and billions of dollars (Stack Overflow; $1.8 billion).

In this role you'll receive one-on-one mentorship from the Founder of HASH.

## 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.
