Full-Stack Engineer

About HASH

HASH's open-source platform helps firms integrate both structured and unstructured information into knowledge graphs that support simulating, optimizing and automating processes. Our 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. We're therefore currently hiring exclusively in both London (UK) and Berlin (Germany) to join the firm.

About the role

Full-stack engineers implement the majority of HASH's user-facing features. They write code on the frontend and backend, unblocking themselves, and ensuring HASH responds to user needs and ships new functionality fast. We are hiring new engineers based in London, UK as well as Berlin, Germany to join our team in-person.

Requirements

• You must possess expert-level proficiency in TypeScript and React. Additional experience with Rust is nice-to-have but not required.
• Experience working with Effect and HTML Canvas, as well as frontend graphics and animation libraries are also beneficial, as is familiarity using and customizing component libraries such as Material UI, Base UI or Ariakit, and working with type-safe styling systems like Panda.
• You should be interested in not only moving fast, but also in building performant solutions.
• In this full-stack role, you should be as comfortable optimizing data structures and storage systems as you are in pushing front-end web frameworks to their limits. If you are more interested in frontend engineering only, see our separate FE Engineer opening(s).

What you'll work on

• You'll work on both the frontend and backend of new features at HASH, touching most parts of the HASH codebase.
• The vast majority of your work will be open-source, and many of the components you build should be designed modularly, supporting their use in third-applications, as well.
• You'll collaborate directly with experienced, organized, and technical UX/UI designers in addition to company leadership (both the CEO and CTO).

Benefits

We offer leading equity-weighted total compensation, including competitive salaries and tax-advantaged options. We also offer:

• Employer pension contributions
• At least 30 days holiday annually
• Twice-yearly in-person team retreats around the world

HASH's founders have previously founded and sold companies like Stack Overflow and Trello for hundreds of millions and billions of dollars.

This role pays £60,000-£110,000 base/bonus + meaningful equity.
