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 Fullstack 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 - along with the services and systems that power them, driving 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, work through scope, risks, and open questions, 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, complex initiatives. Own technical execution from problem framing and scoping through implementation, launch, and iteration - across Front's client-side surfaces (Web, Desktop via Electron, and Mobile) and the backend services, APIs, and data systems behind them. Drive decisions and deliver reliably and on time. - Drive technical direction across the stack. Influence architecture, state management, API design, and performance strategy for high-traffic, distributed workflows like inbox triage, message rendering, and composition - reasoning across systems, services, and stacks to make sound tradeoffs. - 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, surface open questions, 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 across frontend and backend. Reduce regressions and enable faster iteration through better tooling and code health. - Grow others and strengthen the team. Give and receive feedback well, 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? - Strong fullstack experience, comfortable working across systems, stacks, and distributed systems rather than a single layer. - A track record of leading projects and delivering complex work in a timely manner - driving decisions and working through ambiguity end to end. - Experience collaborating closely with Product and Design to work through scope, risks, and open questions before and during delivery. - Ability to give and receive feedback constructively. - An agile, scrappy mindset - comfortable learning new technologies, adapting quickly, and doing what it takes to ship when the situation calls for it. Front operates on a hybrid model - we come together in the office each Tuesday, Wednesday, and Thursday to collaborate and stay connected. What we offer - Competitive salary - Equity (we are post-series D & backed by some of the best VCs in the US) - Private health insurance, including plan options at no cost to employees - Paid parental leave - Flexible time off policy - Flexibility to work from home Monday and Friday, unless posted as a fully remote role - Mental health support with Workplace Options - Family planning support with Maven - $100 per month Lifestyle Stipend to spend on fitness, health and wellness, and other activities - Wellness Days - Fronteers get an additional day off on months with no holidays - Winter Break - Our offices are closed from Christmas to New Year's Day!
