Senior Product Engineer (w/m/d)

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. 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, TypeScript, and Tailwind CSS.
Implement performant, scalable UI patterns with a strong emphasis on component reuse and long-term maintainability.
Performance, Quality, and Reliability
Design and optimize Server-Side Rendering (SSR) and related performance strategies to ensure fast load times and excellent UX.
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.

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.
4+ years of professional experience building modern web applications.

• Deep experience with TypeScript, 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.
• 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.

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.

We value speed, but not at the expense of quality or user experience
Product, design, and engineering collaborate tightly and iterate quickly
