Senior Java Developer Lead Developer Java, NodeJS, AWS - High-Growth Marketpl

We are building a next-generation, large-scale marketplace with embedded payment systems, operating entirely on a serverless AWS infrastructure. We seek a unique technical leader whose true value lies in consistently understanding and analyzing every technical challenge in the context of the entire platform—covering both software and infrastructure. This role is not just about building features, but about abstracting requirements to their essential core, creatively finding lean, innovative solutions, and transforming complex demands into elegant changes within our existing structures.

Key responsibilities

Holistic platform perspective: analyze and solve technical problems with consideration for the full platform architecture (software + infra, serverless AWS, payments).

High-level abstraction: break down and reframe feature requests into their core requirements. Challenge assumptions and discover more effective, less complex approaches, often achieving the same goals with far less code and complexity.

Technical design mastery: drive the design of technical “masterpieces”—critical, scalable solutions, and constantly scrutinize reliability, performance, coherence, and development best practices.

Communication & collaboration: translate complex problems clearly to other developers and stakeholders. Foster open, analytical dialogue and knowledge sharing within the team.

Team leadership potential: play a vital role in mentoring, shaping, and potentially managing a rapidly growing engineering team. Be ready to step into either a hands-on technical architect or team management function as the team evolves.

Learning & adaptiveness: lead by example with intellectual curiosity, and a willingness to learn, experiment, and challenge outdated practices. Engage with experts, but never accept “that’s just how it’s done” without true analysis.
