Role Overview

We are seeking a highly experienced Lead / Principal Java Engineer to design and build next-generation distributed systems across backend services, edge computing, and AI/ML platforms.

This is a hands-on technical leadership role for an engineer who can take complex systems from 0 to 1, make architectural decisions, and write production-quality code. The ideal candidate thrives in an ambiguous, fast-moving environment and enjoys working across multiple technical domains.

Key Responsibilities

  • Design and build end-to-end distributed systems spanning edge detection, ingestion APIs, processing, storage, and downstream services.

  • Develop highly scalable backend services using Java and Spring Boot.

  • Design and implement APIs, microservices, event-driven architectures, and data processing pipelines.

  • Architect and develop solutions using AWS and edge/CDN computing technologies.

  • Build solutions for data normalization, feature pipelines, and ML model serving/integration.

  • Design third-party integrations including identity, authentication, token validation, and secure data exchange.

  • Make technical decisions around storage, reliability, observability, security, and governance.

  • Work closely with data science, product, and engineering teams to move AI/ML capabilities from experimentation into production.

  • Lead technical design discussions and communicate architecture decisions across teams.

  • Take ownership of greenfield initiatives from concept through implementation and production.

  • Use AI-assisted development tools such as GitHub Copilot and LLM-based coding assistants to improve engineering productivity.

  • Mentor other engineers and provide technical leadership through hands-on development and design.

  • 10+ years of experience building production distributed systems.

  • Strong expertise in Java and Spring Boot.

  • Extensive experience with REST APIs, microservices, event-driven architectures, and distributed systems.

  • Strong AWS experience across compute, storage, networking, and IAM.

  • Hands-on experience with edge computing, CDN execution environments, edge workers, Lambda@Edge, or similar technologies.

  • Experience building data platforms or systems supporting ML inference and model serving.

  • Strong understanding of system design, scalability, reliability, observability, and security.

  • Proven experience taking systems from 0 to 1 in an environment with evolving requirements.

  • Strong communication skills with the ability to influence technical decisions across teams.

  • Demonstrated experience using AI-assisted development tools and LLM-powered engineering workflows.

Nice to Have

  • JavaScript / TypeScript experience.

  • Python experience for data engineering or scripting.

  • Databricks or similar data/AI platforms.

  • Experience with ML model registries and feature platforms.

  • Knowledge of JWT/JWS, PKI, OAuth 2.0, identity, or token verification.

  • Experience with distributed tracing, structured logging, and observability platforms.

  • Experience building multi-party integrations or network/platform services.

  • Open-source contributions.
