Senior Software Engineer (Frontend), Core Product Experience

About this role

Front is the customer operations platform built for B2B complexity, keeping every team, tool, and customer conversation in sync so companies can scale without losing connection. Others handle simple interactions. Front handles the coordination and context behind complex B2B customer relationships. Over 9,000 companies, including Uber Freight, Navan, and Stripe, rely on Front because it's the only one that can run the operational layer that makes customer-facing work actually succeed.

Backed by Sequoia Capital and Salesforce Ventures, Front has raised $204M from leading venture capital firms and independent investors including top executives at Atlassian, Okta, Qualtrics, Zoom, and PagerDuty.

The Core Product Experience (CPX) team owns and elevates the heart of the Front application — the inbox and adjacent surfaces where frontline users triage and route conversations, collaborate with teammates, and craft high-quality replies. CPX's mission is to ensure that frontline and admin users can work more efficiently, with higher quality, and a happier day-to-day experience. The team's scope is broad, spanning everything from core inbox functionality (inboxes, message list, composer) to newer surfaces like calendar and contacts. CPX partners closely with Client Platform, AI, and other pods across Engineering to deliver cohesive, high-impact experiences. As Front continues to invest in AI-powered workflows, CPX is at the center of the product strategy.

We’re looking for a Senior Frontend Software Engineer with strong product and design sensibilities to help lead this work. You’ll build and evolve the surfaces that the vast majority of Front interactions pass through — the inbox, messages, and composer — and you’ll drive projects that directly improve speed, quality, and usability for thousands of customers.

This is not a “build to spec” role. We want a senior engineer who helps shape what we build and why, leads delivery through ambiguity, and sets a high bar for engineering craft. You will work closely with Product and Design to define solutions, make thoughtful tradeoffs, and ship experiences that are technically excellent and delightful to use.

What will you be doing?

- Lead end-to-end delivery of high-impact frontend initiatives. Own the technical execution from problem framing and scoping through implementation, launch, and iteration across Front’s client-side surfaces (Web, Desktop via Electron, and Mobile).

- Drive technical direction for complex UI systems. Influence architecture, state management patterns, and performance strategy for high-traffic workflows like inbox triage, message rendering, and composition.

- Champion UX craft and product thinking. Hold a high bar for interaction details, accessibility, and polish. Advocate for the user and improve experiences based on feedback and metrics.

- Partner deeply with Product and Design. Collaborate early to shape requirements, identify risks, propose alternatives, and align on tradeoffs. Communicate clearly and proactively with cross-functional stakeholders.

- Raise the bar for quality and maintainability. Improve testing, observability, and engineering standards. Reduce regressions and enable faster iteration through better tooling and code health.

- Grow others and strengthen the team. Provide mentorship and constructive code review, share best practices, and help create a collaborative, low-ego engineering culture.

What skills and experience do you need?

Must Have:

- 7+ years of professional experience building complex, production web applications with a focus on frontend engineering

- Deep proficiency with modern frontend technologies — React, TypeScript, and state management patterns (e.g., Redux)

- Demonstrated technical leadership — you’ve led projects, driven alignment, and delivered outcomes across multiple stakeholders

- A strong ownership mindset — you take responsibility for outcomes end-to-end, including reliability, maintainability, and post-launch iteration

- High bar for UX — you ship polished, accessible experiences and care about what makes a product feel fast, intuitive, and delightful

- Excellent communication and collaboration skills — you articulate tradeoffs clearly and work effectively with cross-functional partners

Should Have:

- Experience building and evolving shared systems such as component libraries, design systems, and platform patterns

- Strong performance and debugging skills, including profiling, reducing re-renders, and improving perceived performance

- Pragmatic problem-solving — you understand tradeoffs and value shipping iteratively without sacrificing long-term quality

Nice to Have:

- Experience with Electron or desktop applications

- Experience in high-volume, real-time, or collaborative UI (rich text editing, multi-user state)

- Experience in B2B SaaS, productivity, collaboration, or customer communication products

What makes this role exciting?

- Your work is the product. CPX is where users spend hours every day. Improvements you lead are felt immediately by thousands of teams worldwide.

- Real ownership and influence. You’ll help define the roadmap with Pr
