AI Success Engineer

# 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 AI Solution Engineers in **London** and **Berlin** to help build real-world applications for our customers utilising 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
• **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

• **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 recognise and reward output.
**This role is primarily performance-incentivized and pays €70,000-€120,000 base/bonus, plus meaningful equity.**
