Job Description: Role
Who you are
This work demands strong technical judgment, product intuition, and a willingness to think end to end. It’s challenging and that’s exactly why we enjoy it
You've either been a technical founder or one of the top five developers at a small or mid-sized company
You’re used to figuring things out, moving fast, and taking real ownership which are the exact qualities that thrive here
What matters most is strong fullstack fundamentals, systems thinking, product sensibility, and the ability to reason clearly about complex behavior across the entire application
What the job involves
We power mission-critical workflows like automations, data transformations, AI orchestration, permissions, and integrations and all surfaced through interfaces that need to feel fast, clear, and human
As a fullstack engineer, you work across that entire spectrum: from data and execution engines to UI, interaction patterns, and product behavior
The goal is simple but demanding: build systems that are powerful under the hood and effortless to use on the surface
First, we build horizontal systems that compound over time. We don’t hardcode “solutions”, we create primitives. A change to a data model, API, or UI pattern should unlock dozens of new use cases across the product
Fullstack engineers are central to that leverage, because they understand both how the system works and how it’s experienced
Second, we’re building for the age of AI. That changes everything: how data is structured, how workflows are orchestrated, and how interfaces behave
Backend systems must be deterministic and auditable; frontends must become adaptive, conversational, and personal. Fullstack engineers help bridge that gap, designing flows where AI, software, and humans work together without friction
We’ve got a solid setup, and you’ll get support when you need it, but we also expect you to be proactive: ask sharp questions, challenge assumptions, and ship with confidence
Our engineers open their first PR in days and ship to production in week one
We optimize for velocity, clarity, and collaboration, not layers of process
Since we’re building a collaborative product, communication matters: explaining your thinking, giving clear feedback, and working closely with others across engineering, product, and design
Longer-term, you may grow into a team lead role or already operate at Staff level. Either way, you're here to level up and after a year at Planhat, we’d expect you to be in the top 50% of the team
The team has already solved challenges like time series architecture, building a store of stores. And we’re just getting started
Planhat is built on a modern, modular architecture across the stack
You’ll work with JavaScript, TypeScript, Node.js, and Vue.js, designing APIs, data models, and workflows on the backend while shaping intuitive, high-performance interfaces on the frontend
A big part of the role involves connecting these layers thoughtfully: ensuring that backend capabilities surface naturally in the product, and making sure the backend is designed around the product and UI needs, not the other way around

Our take

Although acquiring customers is essential for the initial growth of a company, long-term sustainable growth comes from maximising the lifetime value of existing customers. To help with this, Planhat provides a customer platform that lets clients analyse insights regarding their target audience, as well as manage workflows and drive customer experience.
Planhat distinguishes itself from other customer success software like Salesforce and Totango through its rapid deployment and easy adoption. The platform provides a range of solutions, from customisable customer health scores to management reporting and CSM team performance. It's been taken up by thousands of teams globally and its corporate customers include the likes of Consensys, Alation and Adenza.

Initially a bootstrapped company, Planhat had already built a significant business by the time it closed its first investment round in 2022. With this support, the company has focussed on scaling both its commercial and R&D functions, further developing the product and growing the business.
