About the role

We're looking for a senior frontend engineer to join our newly formed Value-Led Growth team and help shape how we grow Buffer through genuine customer value. You'll take the lead on building core parts of our growth experience, including referral programs, conversion flows, free tools, and data-driven experimentation features.

We need someone with strong product instincts, growth domain experience, and the ability to work independently across team boundaries. You care about metrics and user behavior as much as polished UI — thoughtful conversion flows, data-driven decisions, and experiences that genuinely serve our users. You'll collaborate closely with our Staff Growth Product Manager, engineers from other teams, and various stakeholders to explore opportunities, validate ideas, and ship high-impact growth initiatives.

We're a small, collaborative team that puts value before revenue in our decision making. We iterate based on real user data, care deeply about long-term customer relationships, and focus on building trust through exceptional experiences. You'll have space to lead, evangelize growth thinking across Buffer, and help establish the foundations of our growth engineering culture.

What you’ll do

Lead the development of core growth features — referral systems, conversion flows, free tools, pricing experiments, and social viral loops that drive sustainable user acquisition and retention.
Drive growth experimentation — implement A/B tests, track key metrics, and build the infrastructure that enables rapid iteration and data-driven decision making across growth initiatives.
Collaborate across teams, you'll work closely with other teams to identify growth opportunities and implement solutions that span multiple domains.
Shape growth platform capabilities, build tools and systems that enable other teams to easily implement growth features, run experiments, and optimize their own conversion funnels.
Shape frontend architecture and UI standards, guide technical decisions from state management and component structure to evolving our internal design system (Popcorn), refining shared patterns, and ensuring our interfaces remain consistent, accessible, and scalable across growth initiatives.
Take shared ownership of product quality and system health. You'll participate in our on-call rotation — all engineers take a 24/7 week-long shift roughly once a quarter. You'll also contribute to the ongoing work that keeps our systems running smoothly and continuously improving, like fixing bugs, addressing security vulnerabilities, and other improvements
Contribute to shaping our team’s engineering culture by sharing knowledge, reviewing code, and helping us all get better over time.

Helpful skills and experience

You have solid experience building interactive, user-facing applications with modern web tech — we use React, TypeScript, and GraphQL, but we care more about your ability to reason well and learn quickly than a specific stack.
You understand growth domain challenges — maybe you've built referral systems, optimized conversion flows, or implemented experimentation frameworks — and you enjoy solving problems that directly impact business metrics.
You're comfortable with data and analytics — you can set up tracking, analyze experiment results, and make data-driven decisions about feature development and optimization.
You have strong product judgment and a good sense of taste. You notice the small things, care about the feel of an interface, and bring a high bar to the UI details that shape user experience.
You’re comfortable navigating ambiguity and working independently, can drive technical discussions across teams, and help establish engineering practices for a growing team.
You’ve led significant frontend initiatives or projects, bringing clarity and direction to complex problems and guiding work from early exploration through to delivery.
You have a personal stake in the world of content creation, maybe you’ve run a newsletter, built an audience on social media, or regularly share your own work online. You’ve used Buffer before and care about the experience of planning, creating, and publishing content.
You thrive in remote, async environments. You communicate clearly, support your teammates, and don’t wait for permission to make progress.
You’re product-minded and user-oriented — you think beyond the ticket, consider edge cases and user experience, and bring a strong sense of ownership to your work.
You’re comfortable working with backend code when needed, and you understand how frontend decisions connect to the bigger picture.
You’re fluent with AI tools and use them to work with more leverage and level up your own efficiency.
You’ve likely been doing this for 7+ years, but depth matters more to us than a specific number.

Our tech stack

We use React and TypeScript for our web frontends
We have internal design system called Popcorn that we started developing last year, it is built with Radix primitives, CSS modules, Storybook and our own system of design tokens
We are in the process of migrating to GraphQL, we use Apollo Client in our web application
We write automated tests with jest, react testing library (for integration tests) and Playwright (for e2e tests)
On the backend, we use NodeJS, TypeScript and MongoDB
We are running our services on AWS with Kubernetes. We follow a micro-services architecture and are currently moving our services into a central shared monorepo.
