Staff Engineer

Description :

Responsibilities :

- Own architecture and scaling decisions for key Course platform components (e. g., Analytics Engine, Insights Platform, Data Ingestion Pipelines).

- Lead design and execution of cross-cutting initiatives to improve reliability, latency, and throughput across time-sensitive APIs and workflows.

- Work hands-on with technologies like NestJS, Firestore, MongoDB, MySQL, Redis, Queuing Systems, Data Warehousing Systems and Service Mesh-based microservices.

- Drive observability and resilience by evolving our monitoring, alerting (Prometheus/Grafana), and incident response strategies.

- Leverage LLMs and AI tools to write, refactor, test, and debug code efficiently while implementing guardrails to reduce hallucination and boost reliability.

- Partner with product, infra, and security teams to ensure data integrity, access control, and compliance across phone services.

- Mentor and guide a team of high-performing engineers, encouraging technical excellence and career growth.

- Stay on the bleeding edge of AI/LLM technology, development best practices, and distributed architecture patterns and bring that knowledge back to the team.

- Participate in design reviews, deep dives, and on-call rotations to support a high-bar culture of accountability and operational excellence.

Requirements :

- 10+ years of backend engineering experience, including designing fault-tolerant systems and working on high-scale platforms.

- Deep expertise in distributed systems, event-driven architectures, and asynchronous job processing.

- Proven experience optimising availability, performance, and reliability in real-world systems under load.

- Strong experience with relational and NoSQL data models (especially with complex transactional data).

- Experience with Data Analytics Pipelines, OLAP, and OLTP databases.

- Familiarity with monitoring, SLOs, and root-cause analysis in production environments.

- Familiarity with hallucination mitigation strategies (e. g., code constraints, test scaffolding, embeddings, context injection).

- Excellent communication and cross-functional collaboration skills.

- A pragmatic, hands-on leader who balances long-term vision with iterative execution.
