About the Role

We’re looking for a Senior Lead Developer to take ownership of our in-house report execution engine — a fast, performance-critical system that runs subsecond queries across different data sources, sometimes combining them on the fly.

This is a hands-on leadership role for a developer who enjoys going deep into a single, technically challenging system. We're not looking for a high-level architect – we need someone who still writes code, makes smart technical decisions, and leads through hands-on work.

You’ll take ownership of a performance-critical platform, guiding its architecture, improving reliability, and shaping how we build – all built on a modern, cloud-native stack.

What You’ll Do

Own the technical direction, architecture, and performance of the report execution engine Design and build systems using Python, Java (Spring Boot), Redis, and AWS Lambda, along with other cloud-native technologies like ECS/EKS, Docker, and Kubernetes Lead technical decision-making, define coding standards, and help the team stay aligned on best practices Work closely with architects, engineers, and other teams to ensure everything integrates smoothly Review code, troubleshoot tricky issues, and help others grow through feedback and collaboration Improve how we test, monitor, deploy, and evolve the platform over time

What We’re Looking For

10+ years of software development experience 5+ years in a technical leadership or architecture-focused role Strong communication skills in English, both written and verbal Proven experience building and operating high-throughput systems in the cloud (preferably AWS) Strong experience building systems in Python and using Redis at scale Proficient with Java and familiar with frameworks like Spring Boot and Hibernate Experience with REST APIs, event-driven architecture, and microservices Comfortable working with both relational (Oracle) and NoSQL (MongoDB, DynamoDB) databases Familiar with CI/CD workflows, Git, and tools like Jenkins Comfortable working with Infrastructure as Code (Terraform preferably) in cloud-native environments

Bonus points for:

Knowledge of relational algebra or query planning/optimization concepts Experience with Apache Calcite, Kafka, or DAG-based pipelines (Airflow, Step Functions)

Why This Role Stands Out

You’ll own a core platform — not just maintain it, but actually shape where it goes You’ll work on a system that’s small enough to move fast, but big enough to matter. Decisions are made by people who build the thing — not layers of management You’ll have the freedom to make architectural decisions, try new ideas, and influence how we build software

What Success Looks Like

You’ve made this engine stable, fast, and ready for what’s next You’ve made improvements that directly impact how fast and confidently we can ship You’ve become the go-to person for deep technical questions and forward-looking planning You’ve contributed to architecture and design decisions, bringing clarity and forward momentum to the team You’re a trusted contributor — someone others turn to for technical input, context, and delivery confidence
