Key Responsibilities
Understand client objectives and develop strategies to meet them, incorporating client feedback into product development. Own end-to-end delivery: break down complex problems into iterative, shippable components. Collaborate with Product and User Experience teams on roadmaps and rapid iteration cycles. Lead technical architecture and solution design. Develop a deep understanding of the company’s product suite and provide technical expertise plus production support to clients. Manage delivery of on-premises and cloud-based deployments, upgrades, and enhancements. Mentor engineers and contribute to a high-performance engineering culture.
What We’re Looking For
Experience in building web applications using User-Centered Design principles. Strong system design skills, particularly architecting scalable end-to-end solutions. Ability to propose and articulate multiple solutions, weighing technical and business trade-offs. Track record of owning long-term projects from concept to delivery. High curiosity, strong problem-solving skills, and comfort asking thoughtful questions. Experience collaborating directly with clients or end-users. A collaborative mindset with a passion for knowledge sharing. Openness to giving and receiving feedback in a constructive environment.
Desired Technical Skills
Backend: Proficiency in Java and/or Node.js with TypeScript. Frontend: Strong experience with React and TypeScript. Infrastructure: Familiarity with cloud environments (e.g., AWS, Azure). Databases: Experience with relational databases (Postgres, Oracle, etc.). APIs: Experience designing and building RESTful APIs. Bonus: Experience with functional programming (Clojure, Haskell).
