Key Responsibilities

• Provide technical leadership: set architecture direction, decompose projects, mentor engineers, and drive high‑quality delivery with rigorous reviews.
• Build and evolve backend services and APIs in Django/Python with performance, reliability, and maintainability at the forefront.
• Own the data layer: design efficient relational schemas in PostgreSQL, tune queries, and manage migrations via SQLAlchemy and Alembic.
• Implement robust CI/CD: define branching strategies in Git, automate build/test/deploy, and ensure safe rollbacks and environment promotion.
• Optimize runtime: apply Redis caching and Nginx reverse proxying for throughput, latency, and secure traffic handling.
• Collaborate cross‑functionally with product and operations to translate requirements into executable technical plans.

Required Qualifications

• 7–10 years in software development with deep expertise in Python and Django, delivering production web backends and RESTful APIs.
• Proven leadership experience guiding engineers, setting standards, and conducting design and code reviews.
• Strong RDBMS knowledge: schema design, indexing, transactions, and performance tuning on PostgreSQL.
• Hands‑on with SQLAlchemy and Alembic: model definitions, schema versioning, safe forward/backward migrations, and rollbacks.
• CI/CD and Git: pipeline design, gated testing, release automation, and effective branching/review workflows.
• Redis and Nginx: practical experience with caching strategies, eviction patterns, and secure high‑throughput proxying.
• Working knowledge of NoSQL paradigms and when to apply them alongside relational stores.

Nice to Have

• Exposure to Payment Gateways (like Adyen, Stripe etc.) integrations.
• Cloud‑native delivery (Docker/Kubernetes) and infra‑as‑code within CI/CD workflows.
• Observability practices: metrics, logs, and tracing for performance and reliability improvements.

Success Indicators

• Faster, safer releases with clear Git strategies and automated pipelines (improved lead time and change failure rate).
• Stable, scalable Django services with efficient PostgreSQL schemas and safe, auditable migrations.
• Measurable latency/throughput gains via Redis caching and Nginx tuning, backed by observability data.

Preferred Educational Background

• Bachelor’s/Master’s degree from IITs/IIMs or equivalent top rated institutions
• Proper certifications on the subject
