Senior Lead React Developer Jobs

About The Role & Team Amplitude is the leading AI analytics platform, and our ability to deliver measurable customer outcomes quickly is a key part of how we keep that lead. The Customer FDE (Forward Deployed Engineering) team sits at the intersection of engineering, product, and customer success — owning the technical delivery that takes validated products from co-development and implements them across enterprise customers. As a Customer Forward Deployed Engineer, you will own end-to-end technical delivery for enterprise customer implementations, from sales engagement through post-deployment validation. You'll work directly in Amplitude's product codebase, submitting PRs, shipping customer-specific solutions, and building reusable patterns that make every successive engagement faster. This is not a traditional support or solutions role. Customer FDEs are engineers first who partner closely with Sales, Customer Success, Product, and Engineering to turn customer needs into working software. The right person thrives in ambiguity, learns new domains quickly, and cares as much about the customer's outcome as about technical elegance. As a Customer Forward Deployed Engineer, you will: Own enterprise implementations end-to-end — engage during sales to map customer needs to capabilities, scope implementation plans, and deliver through post-deployment validation with measurable customer outcomes Work directly in the product codebase — submit PRs, test, and ship customer-specific solutions without requiring constant oversight; over time, the gap between "what we built" and "what the customer needs" keeps shrinking because you're the one closing it Ship early, ship often, and gather feedback — treat every customer interaction as an opportunity to validate your approach and course-correct quickly Build reusable patterns and playbooks — when you solve something once, make sure the next person doesn't have to solve it again; identify and document implementation patterns that

Senior Engineering Manager — Lab Execution Platform : Women’s Health About the Role This is your chance to own a platform that lab scientists rely on every single day—and to rebuild it from the ground up. You'll lead maintenance of our off-the-shelf Lab Execution System while driving its transition to a custom, in-house platform. Every improvement you ship makes lab operations faster, makes scientists' lives easier, and ultimately helps improve patient health outcomes. The work is real, the impact is immediate, and the customers are just down the hall. You'll treat Lab Operations and R&D as your primary customers, partnering with them to build an intuitive, efficient, scalable Lab Execution platform they'll love using. You'll lead a small, sharp team in a fast-moving Kanban or Scrum workflow, lean hard into a "do more with less" mindset, and put AI to work multiplying what your engineers can accomplish. You'll stay close to the code while leading with impact and kindness, because the best teams are healthy teams. Key Responsibilities Technical Leadership & Development Own the design, build, and maintenance of both the off-the-shelf and custom Lab Execution platforms, keeping high-throughput lab processes running without a hitch. Build an AI-forward team that reaches for modern tooling to move faster and ship smarter. Stay hands-on—dive into the code and test the system yourself to make it better. Build and scale cloud-based microservices and front-end applications that power real lab workflows. Set the bar for technical excellence: reliability, performance, and a user experience people actually enjoy. Own the CI/CD pipeline and lock in quality with automated testing. Architect infrastructure that scales effortlessly and stays cost-smart. Customer-Focused Collaboration Be the bridge between engineering and lab users, turning real-time feedback into rapid improvements. Build tight relationships with Lab Operations, R&D, and stakeholders so their needs stee

Replit is the agentic software creation platform that enables anyone to build applications using natural language. With millions of users worldwide, Replit is democratizing software development by removing traditional barriers to application creation. The AI Studio is the team responsible for designing, building, and operationalizing internal software platforms across every functional department of the company, including People Operations, Customer Support, Sales, Marketing, Finance, Recruiting, and Executive Operations. We treat each internal department as its own product surface, and in truth as its own startup, with its own customers, its own metrics, and its own reasons for existing. We ship custom software, built on Replit’s own platform, to solve operational problems that off-the-shelf SaaS tools cannot serve well at our scale and pace of growth. Position Summary The Member of Technical Staff (AI Builder) is a full-time builder role with substantial autonomy. You will design, architect, and ship AI-powered internal platforms that run the operations of the company across many departments at once. This is not a role for someone who wants a narrow, well-defined lane. It is a role for someone who wants to walk into an ambiguous business problem, understand it well enough to argue about it with the department lead, and then ship the software that fixes it. We are looking for people who genuinely understand the mechanics of a business: how revenue is actually made, why recruiting velocity matters, what makes support scale or break, how finance closes a month, and why each department is critical to whether the company wins or loses. You do not need to have run every function, but you need to respect why each one exists and be able to reason about it like an operator, not just an engineer. Because we treat each department as its own startup, we strongly favor people who have either run their own business or worked on a fast-scaling startup. You know what it feels like
