This is a highly collaborative and client-facing role for an experienced technologist who is equally comfortable writing code, leading technical delivery, discussing architecture with senior stakeholders, and helping teams make better engineering decisions.\nWe’re particularly interested in engineers with deep React and TypeScript expertise, strong experience building on AWS, and a modern approach to software development that incorporates AI-assisted and agentic coding tools into everyday engineering workflows.\nRequirements:\nExtensive professional software engineering experience building and delivering complex, production-grade applications.\nDeep expertise in React and TypeScript, with strong experience designing and developing modern frontend and full-stack applications.\nStrong understanding of software and solution architecture, including the ability to make pragmatic architectural decisions around scalability, performance, maintainability, and reliability.\nSignificant experience with AWS and cloud-native application architectures, including serverless, containerized, and/or distributed systems.\nProven experience serving as a Tech Lead, Principal Engineer, or senior technical owner for complex engineering initiatives.\nAbility to lead projects from technical discovery and architecture through implementation, deployment, and production.\nStrong experience designing and integrating APIs, backend services, and distributed systems.\nHands-on experience using modern AI-assisted development tools such as Claude Code, GitHub Copilot, Cursor, or similar technologies as part of software delivery.\nUnderstanding of agentic coding and AI-enabled software development workflows, including how these approaches can improve engineering productivity without compromising quality or maintainability.\nStrong consulting skills with the ability to understand client challenges, identify technical opportunities, and translate business requirements into effective engineering solutions.\nExcellent communication and executive presence, with the ability to explain complex technical concepts, trade-offs, and recommendations to both technical and non-technical stakeholders.\nExperience collaborating across engineering, product, design, and client teams in distributed environments.\nAbility to mentor engineers, establish technical direction, and raise engineering standards while remaining actively involved in hands-on delivery.\nBonus points:\nExperience designing or delivering AI-powered or Generative AI applications.\nHands-on experience with agentic architectures, AI agents, orchestration, or LLM-integrated development workflows.\nExperience with additional modern full-stack technologies such as Node.js, Next.js, React Native, or similar frameworks.\nExperience with AWS serverless architecture, including services such as Lambda, API Gateway, DynamoDB, Cognito, or related technologies.\nAWS certifications or demonstrated experience designing complex AWS architectures.\nExperience leading cloud modernization, application modernization, or legacy transformation initiatives.\nExperience conducting technical assessments, architecture reviews, discovery engagements, or consulting workshops with clients.\nExperience helping teams adopt new engineering practices, tooling, or AI-enabled development approaches.\nYou’ll Love:\nSolving complex engineering challenges while remaining deeply involved in hands-on technical work.\nWorking directly with clients and senior stakeholders to shape technical strategy and turn ideas into production-ready solutions.\nLeading engineering initiatives without stepping away from coding and architecture.\nBuilding modern applications with React, TypeScript, AWS, and emerging AI technologies.\nExploring how AI-assisted and agentic development can fundamentally improve how software teams design, build, test, and deliver products.\nMentoring other engineers and helping raise the technical bar across teams.\nWorking across different clients, industries, technologies, and complex business challenges.\nBy joining our team, you’ll be part of a winning squad that plays to each other’s strengths and celebrates every success
