About HASH
At HASH, we're building infrastructure to solve information failure 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.
