As a Senior Software Engineer and hands-on tech lead, you will guide the architecture and delivery of high-impact web capabilities built with JavaScript, TypeScript, React, Node.js, and modern web technologies. The team uses experimentation and a test-and-learn mindset to improve customer engagement and product acquisition.\nYou will combine deep full-stack engineering with team-level technical leadership: owning complex initiatives, making sound architecture decisions, and helping engineers do their best work. You will also help the team make thoughtful use of modern AI coding agents to improve how we design, build, test, and operate software, while holding the bar for customer experience, security, and quality.\nYou will work in an agile, cross-functional group where collaboration, automation, technical excellence, and continuous learning matter. Your work will contribute directly to important customer journeys.\nTechnical Leadership and Decision Scope\nOwn team-level technical decisions, including architecture, engineering standards, and implementation trade-offs within agreed team boundaries.\nSet shared technical direction across projects. Project Leads coordinate project delivery and make project-specific decisions consistent with team standards; decisions with broader architectural or cross-team impact are aligned with this role and relevant partners.\nPartner with the engineering manager, who retains people-management and team-priority decisions. Escalate decisions that exceed the team's technical scope or introduce significant cross-team or customer risk.\nBalance implementation work with architecture, technical guidance, and mentoring; this is a hands-on engineering role, not a full-time coordination role.\nWhat You'll Do\nTechnical Direction and Delivery\nDesign, architect, and deliver complex features across the full web application stack.\nTranslate business needs into technical solutions with Product Owners, engineers, and other partners; break complex problems into clear implementation approaches and communicate trade-offs and risks.\nGuide architecture and design decisions, document significant decisions and rationale, and keep project solutions aligned with team standards.\nExperimentation and Customer Outcomes\nPartner with Product Owners and analytics and design partners to turn customer and business opportunities into testable hypotheses.\nBuild the application capabilities needed to run experiments, such as reliable analytics instrumentation, feature flags, and controlled rollouts.\nEnsure experiments are measurable and meet standards for performance, accessibility, privacy, and reliability; use results to guide iteration, rollout, or rollback decisions.\nApply test-and-learn findings to improve engagement and acquisition across customer journeys.\nEngineering Quality and Production Health\nBuild and evolve secure, scalable, resilient, accessible, and high-performing applications.\nImprove code quality, automated testing, observability, reliability, and maintainability to increase confidence in delivery.\nIdentify and address performance, accessibility, availability, and scalability issues; partner with Site Reliability Engineering on production investigations, root-cause analysis, and lasting fixes.\nTeam Leadership and Improvement\nMentor engineers through technical guidance, code reviews, pair programming, and knowledge sharing.\nSimplify systems, reduce technical debt, and improve team development practices.\nEvaluate technologies and frameworks, adopting them when there is a clear benefit to customers, applications, or engineering effectiveness.\nAI-Native Engineering\nLead practical adoption of modern AI coding agents across engineering workflows, including implementation, test creation, refactoring, documentation, and operational support.\nHelp the team build repeatable ways to work with agents, including clear task context, appropriate human review, and validation through tests and other quality checks.\nUse only approved tools and protect customer, company, and proprietary information; ensure generated changes meet security, privacy, licensing, accessibility, and engineering standards.\nEvaluate whether agent-assisted workflows improve delivery, quality, or developer experience, and share effective practices across the team.\nWhat Success Looks Like\nTeam-level technical decisions and standards are clear, documented where useful, and applied consistently across projects.\nCustomer journeys meet agreed expectations for quality, security, accessibility, performance, and reliability, with risks surfaced early.\nExperiments produce trustworthy insights that inform product decisions and improvements to customer engagement and acquisition.\nProduction issues lead to root-cause understanding and sustainable improvements, not only short-term fixes.\nEngineers are better equipped to make sound technical decisions, and delivery is more predictable through effective collaboration and automation.\nAI coding agents are used through repeatable, responsible workflows that improve engineering effectiveness without compromising quality, security, or customer trust.\n 9+ years of professional software engineering experience, including substantial hands-on experience building modern web applications.\nDemonstrated experience architecting and delivering complex production systems, setting technical direction, and carrying solutions from design through production.\nStrong hands-on expertise in JavaScript and TypeScript, with deep experience in React and Redux or a comparable state-management technology.\nStrong experience with Node.js, REST APIs, Express, and server-side JavaScript or TypeScript development.\nPractical experience with automated testing frameworks such as Jest and Mocha, and with modern JavaScript development practices and web architecture patterns.\nExperience designing and operating applications for scalability, performance, resilience, accessibility, security, and maintainability.\nDemonstrated technical leadership, including mentoring engineers, guiding design decisions, and helping teams reach sound technical outcomes.\nExperience working with Agile development methodologies and DevOps principles, including automated delivery, monitoring, and production support.\nStrong ownership, communication, and collaboration skills, with the ability to work across teams and explain technical decisions and trade-offs.\nA customer-first mindset and a track record of improving digital experiences through engineering quality, automation, and continuous improvement.\nWillingness to experiment with modern AI coding assistants or agents and the judgment to critically review and validate their output.\nEmployment eligibility to work with American Express in the U.S. is required as the company will not pursue visa sponsorship for these positions.","description_format":"text","description_chars":9454,"description_truncated":false,"requirements":{"experience_years_min":9,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Continuous
