Senior Product Engineer

As a Senior Product Engineer, you will own meaningful slices of the product end‑to‑end, from shaping requirements and UX tradeoffs to shipping production‑quality code and iterating based on real user behavior. This role sits at the intersection of frontend engineering, product thinking, and design collaboration.

You will be a core contributor to our primary web application, responsible not just for how features are built, but what gets built and why. You will work deeply with product, design, and backend partners to translate ambiguous ideas into high‑impact user‑facing outcomes.

This is a hands‑on role for engineers who care about craft, velocity, and product truth, and who want real ownership rather than ticket‑driven execution.

What You Will Do:

Product + Engineering Ownership

Own features from problem definition through design refinement, technical scoping, implementation, launch, and iteration

Act as a thought partner to product and design, helping shape scope, sequencing, and tradeoffs rather than waiting for perfect specs

Translate product intent and Figma designs into clear, actionable technical plans, including functional requirements and acceptance criteria

Frontend Architecture and Execution

Architect, build, and maintain high‑quality frontend systems using Next.js, Type Script, and Tailwind CSS

Implement performant, scalable UI patterns with a strong emphasis on component reuse and long‑term maintainability

Build responsive, production‑grade experiences that work seamlessly across mobile and desktop

Performance, Quality, and Reliability

Design and optimize Server‑Side Rendering (SSR) and related performance strategies to ensure fast load times and excellent UX

Integrate cleanly with backend APIs and services, including authentication systems such as Firebase Auth

Maintain a high bar for code quality through thoughtful abstractions, reviews, and technical decision‑making

Collaboration and Technical Leadership

Collaborate closely with product, design, and backend engineers to deliver cohesive, high‑quality features

Surface technical risks and tradeoffs early, influencing product decisions with clear reasoning and data

Set informal standards for frontend quality, testing, and performance through example and mentorship, without heavy process

What Success Looks Like

Features you ship are intuitive, performant, and durable

Product and design partners trust your judgment and proactively pull you into early‑stage discussions

The frontend codebase becomes easier to extend, not harder, as the product grows

You consistently balance speed with correctness, and ambition with pragmatism

Requirements
Required Skills and Experience

4+ years of professional experience building modern web applications

Deep experience with Type Script, React, and Next.js in production environments

Strong command of Tailwind CSS and modern component patterns, including libraries such as shadcn/ui

Solid understanding of SSR concepts, performance optimization, and rendering strategies

Experience integrating authentication and backend services, including Firebase Auth

Strong product intuition and the ability to reason about UX, performance, and technical tradeoffs

Clear written and verbal communication, especially when explaining technical decisions to non‑engineers

Nice‑to‑Haves

Experience with Google Tag Manager (GTM) and Google Analytics (GA)

Familiarity with end‑to‑end testing frameworks such as Cypress or Playwright

Experience with cloud deployment pipelines, including Amplify

A track record of influencing product outcomes through engineering insight, not just implementation

How We Work

We value speed, but not at the expense of quality or user experience

Engineers are expected to think in first principles, not just follow specs

Product, design, and engineering collaborate tightly and iterate quickly

We prefer simple, composable solutions over clever abstractions

Ownership and accountability matter more than titles or ego
