Senior Software Engineer, Frontend Platform About Handshake

At Handshake, our platform connects job seekers with life-changing career opportunities. Behind that mission is a frontend ecosystem that helps teams build clear, consistent, accessible, and high-quality experiences for students, employers, and education partners.

As a Senior Software Engineer on the Frontend Platform Team, you'll help build and evolve that foundation. You'll work on the systems, libraries, and workflows that make it easier for product engineers to deliver great frontend experiences—faster, safely, and with less duplicated effort.

Frontend Platform is a small, high-leverage team with a broad mandate. We own Handshake's design system and component libraries, frontend accessibility, frontend infrastructure in CI/CD, developer tooling, and cross-cutting UI concerns.

You'll treat these capabilities as products for frontend engineers, designers, and product teams. You'll help turn recurring problems into reusable solutions, establish thoughtful standards and paved paths, and create a frontend platform that scales with Handshake's products and engineering organization.

This role is a strong fit for an expert generalist: someone with deep expertise in a few areas and the breadth to move across frontend architecture, developer experience, design systems, accessibility, infrastructure, and product needs.

As a Senior Software Engineer on Frontend Platform, you will:

• Build and evolve reusable Type Script and React components, patterns, APIs, documentation, and tooling that are used across multiple Handshake applications

• Help shape the design system as a living product, balancing consistency and accessibility with the flexibility product teams need to solve customer problems.

• Improve the frontend developer experience by creating clear paved paths for local development, testing, builds, releases, and ongoing maintenance.

• Use AI tools heavily as part of your day-to-day engineering workflow: to understand code, prototype, implement, test, debug, refactor, document, and review changes, while applying sound human judgement.

• Build reusable AI-enabled frontend workflows for the rest of the organization, including agent-ready documentation and context, rules, linters, structured CI review, accessibility and visual checks that helps product teams and agents contribute safely without making our team a bottleneck.

• Strengthen frontend infrastructure in CI/CD, including build, test, lint, packaging, and other workflows that help engineers ship with confidence.

• Make accessibility a built-in capability through accessible component APIs, shared guidance, automated checks, and close partnership with product teams.

• Own or contribute to cross-cutting frontend capabilities that need to work consistently across applications and teams.

• Partner with product engineers, designers, product managers, and other platform teams to understand their needs, make durable technical decisions, and drive adoption of shared solutions.

• Lead projects from problem definition through implementation, rollout, documentation, and iteration based on feedback from platform customers.

• Raise the bar for frontend engineering through design reviews, code reviews, technical writing, mentoring, and knowledge sharing.

We're looking for someone with:

• 5+ years of professional frontend software development experience, with experience operating at a high level of scope and ownership.

• Expertise in TypseScript, React, and the modern frontend ecosystem, including strong knowledge of browser fundamentals, frontend architecture, testing, and performance tradeoffs.

• Experience building or maintaining reusable frontend libraries, design systems, component platforms, or other shared capabilities used by multiple teams or applications.

• Experience working on both product teams and platform, infrastructure, or developer-experience teams—or a demonstrated understanding of the different problem-solving approaches each requires.

• A track record of turning ambiguous, recurring problems into simple, maintainable, and well-adopted solutions.

• Experience designing APIs and…
