React Developer

Hi 👋 I’m Dom, VP of Engineering at Pinpoint.

We’re a high-growth HR tech company building software that helps in-house recruitment teams attract, hire, and onboard the right talent. Today, we have a strong foundation in place, with a mature product, rapid growth, strong product–market fit, and happy customers.

As the business scales, we're moving away from large horizontal teams toward small, verticalized squads, each one owning a specific area of the platform end-to-end alongside a product manager and designer. We're hiring **Senior Product Engineers** who are genuinely excited by that model.

This isn't a role for engineers who build what they're told. You'll be embedded in the problem from the start: understanding real customer workflows, debating trade-offs, shaping solutions, building them, and standing behind them in production. There's no separate discovery phase, no handoff, and no "throw it over the wall" model. Squads own performance, reliability, and quality for everything they build.

We want engineers who build deep context over time and use that understanding to make better product decisions every day, not bespoke client solutions. If you care about owning a problem space, not just shipping tickets, this role was built for you.

**The fine print (but a bit more exciting):**

*   This is a remote role based in the UK or Poland, with occasional in-person team meetups.
*   Our product is a configurable, platform-style ATS serving multiple personas: recruiters, hiring managers, and operations teams across a wide range of complex workflows
*   Our **stack** is pragmatic and maintainable: Ruby on Rails (6.x), React with TypeScript, PostgreSQL, Sidekiq, and CI/CD via CircleCI (moving to GitHub Actions).
*   Pinpoint is still very much in startup mode. Priorities shift, not everything is perfectly defined, and we expect people to operate well in that environment.
*   Curious about how we think and build? **Our engineers write about it here.**
*   Our **values** actually matter here. We hire people who reflect them in how they work, collaborate, and make decisions.

**About the Role:**

*   Build full-stack features using Ruby on Rails and React (TypeScript) within a small, focused squad.
*   Own your product area end-to-end: from understanding real customer workflows and edge cases through to delivery, performance, and ongoing quality.
*   Contribute to architectural discussions and technical trade-offs, not just implementation.
*   Help translate product needs and constraints into clean, maintainable solutions.
*   Review code, mentor others, and raise the technical bar within your squad.
*   Engage continuously with customer context, building the kind of in-depth product understanding that improves your technical decisions over time.

**About You:**

*   5+ years of professional software engineering experience building production web applications.
*   3+ years of production experience with Ruby on Rails.
*   3+ years building React applications in a production environment.
*   Comfortable working with TypeScript (our frontend codebase uses it throughout).
*   Background in startup or scale-up B2B SaaS environments.
*   Comfortable operating in ambiguity and taking end-to-end ownership.
*   Experience working on multi-persona, workflow-heavy SaaS products.
*   Strong written communication — clear, direct, and able to explain technical decisions to non-engineers.
*   Technically curious with a genuine interest in the problem space, not just the code.
*   Experience writing automated tests (RSpec, Jest, or similar).

Senior Product Engineer

**Principal Full Stack Engineer - Profitable Early Stage Start-Up - Python / Typescript_Fully Remote (UK)_**

This is not your typical dev role. You’ll be at the heart of product decisions, working end-to-end across the stack to create experiences that users genuinely love. If you think like a product owner, obsess over user outcomes, and care as much about _why_ you’re building something as _how_, you’ll fit right in.

**You’ll be:**

*   Owning features from idea to production - and beyond
*   Collaborating closely with design and product to craft impactful solutions
*   Moving fast, iterating often and learning from real user feedback
*   Leveraging modern AI tools to **supercharge your workflow**, from prototyping to debugging to scaling ideas faster than ever

**We’re especially excited if you:**

*   Thrive in a **product-first mindset**, not just ticket delivery
*   Are confident across the full stack and enjoy jumping between frontend, backend, and everything in between
*   Already use (or are eager to use) AI tools to **build smarter, faster, and more creatively**
*   Love experimenting, shipping, and continuously improving

This is a chance to build meaningful products, move quickly, and work in a team that values curiosity, ownership, and innovation.

If you want your code to have real impact - and you’re excited by the future of AI-powered development - we’d love to hear from you.
