Job description

People & Talent Product Engineer

Hi I'm Ash Rama, VP People at hyperexponential.

I lead the team responsible for how hx makes decisions about its people: comp, performance, org design, and increasingly, the systems and tools that power all of it. We don't buy software off the shelf when it doesn't fit how we actually want to work, we want to build it ourselves, bespoke to hx. This means shipping everything from simple internal letter-writing tools to a full multi-level compensation platform used by every employee and manager here.

I'm hiring a product engineer to join the People & Talent team, within Central Functions and become the builder behind these tools: someone who can take a prototype, decide how it should actually work and feel for the person using it, then build it out to the highest of hx standards, end to end, back end, data, infrastructure, and ship something that holds up under real use.

This isn't a typical engineering role. You'll sit close to People & Talent day to day, but work alongside our IT and Security teams to make sure everything we build is secure and compliant by design, not bolted on after the fact. I think this is the future of how People functions will operate in the AI era: technical, product-minded, building rather than configuring. If that excites you more than a conventional engineering role would, I'd love to hear from you.

About Central Functions

Central Functions is the core of hx, laying the road for the business to execute on. We bring together Finance, Legal, People, Talent, and Business Operations, the connective tissue that lets every other part of hx move fast with confidence. You'll sit inside this function, working closely with People & Talent day to day, and partnering with IT and Security to make sure everything you build is secure and compliant from the ground up.

Reporting line and engineering partnership

This role reports into our VP People. You'll also work in close partnership with a senior or staff-level engineer from our core Engineering team, who'll sense-check technical decisions and review your work. This isn't day-to-day pairing or management; you'll operate with real autonomy, with that partnership acting as a technical backstop rather than a supervisor. We're looking for someone with 2-4 years' experience who can own a build with real autonomy.

What you'll be doing

• Act as product engineer for People & Talent, owning the full arc from problem framing and experience design through to technical build and delivery, for tools spanning simple internal utilities to our multi-level compensation platform.
• Make the UI and design calls that matter for how people across hx actually experience these tools, whether that's an employee submitting a request or a manager running calibration, turning "we need this to work" into something genuinely well-designed and intuitive.
• Take front-end prototypes built across People & Talent and turn them into production-ready products, full stack: building out the back end, data model, and infrastructure to make them reliable and scalable.
• Spec new builds properly before writing code, mapping the experience and delivery plan (who uses it, how, what "done" looks like) alongside the technical architecture, so nothing gets built twice or built wrong.
• Iterate on live tools based on real user feedback, treating internal People & Talent products with the same product rigour as anything we'd ship externally.
• Work with highly sensitive employee and compensation data, following hx's data protection and security policies closely, and help shape them as our tools evolve.
• Grow into a genuinely unusual specialism: product engineering for People & Talent, sitting at the intersection of software engineering, UX, security, and people operations.

What good looks like

• Within 3 months: existing tools that have already been prototyped and tested, ones already proven to be incrementally helpful, are live in production and released to the business.
• Within 6 months: a high-impact tool, such as compensation management, is built and in testing.

What you'll need to have done

• 2-4 years' experience as a full stack or product engineer, having owned a tool or feature end to end, from spec through to production, not just contributed to someone else's build.
• Made significant UI/UX decisions with real users in mind, and can point to specific choices you made and why, not just features you shipped.
• Operated with real autonomy, as the primary or sole engineer on a project, comfortable making calls without close day-to-day technical supervision.
• Full stack development experience, front end and back end, including some ownership of data models and infrastructure decisions such as hosting, access control, and monitoring.
• Worked with sensitive or regulated data, or is comfortable operating within data protection and security policy constraints.
• Bonus, not required: prior exposure to People, HR, or Talent systems or processes.
