About Role

We’re seeking a hands-on Full Stack Tech Lead with deep experience in Python and C#/.NET to design, build, and scale backend services, APIs, and integrations that power mission-critical workflows. You will own end-to-end delivery—from discovery and technical design to coding, automated testing, CI/CD, deployment, and production support—while ensuring performance, reliability, and security are baked into every stage. You’ll influence architecture decisions, establish coding standards and reusable libraries across Python and .NET, and make observability (logging, metrics, tracing), performance tuning, and security hardening (OWASP, secrets management) first-class concerns. You will collaborate with product managers and architects to translate requirements into elegant solutions, partner with DevOps. Although there are opportunities to mentor and guide peers, this role remains strongly hands-on, with the majority of time dedicated to writing and reviewing code, solving complex technical problems, and improving systems. Success means shipping maintainable, well-documented services, reducing operational toil through automation, and elevating engineering practices across the team.

KEY RESPONSIBILITIES

• Own end‑to‑end solution design, technical roadmap, and delivery for key modules and services

• Build and maintain back‑end services in .NET Core (C#) and Python (FastAPI / Django / Flask); expose RESTful/GraphQL APIs

• Lead front‑end delivery using React.js / Angular

• Establish and maintain CI/CD pipelines in Azure DevOps; enforce code quality, code reviews, test automation, and release governance

• Containerize services (Docker) and deploy to Azure (AKS/App Services); drive 100% production reliability with horizontal scaling

• Design effective data models and access layers using MongoDB and SQL Server/Azure SQL; optimize performance and cost

• Implement security best practices (OWASP Top 10, secrets management, RBAC/SSO with Azure AD) and partner with InfoSec for compliance (ISO/DPDP)

• Set up monitoring/observability (logs, metrics, alerts), manage incidents, and drive post‑mortems and SRE practices

• Plan sprints, manage dependencies, and communicate status/risk to stakeholders

• Produce clear technical documentation (HLD/LLD, runbooks) and collaborate with global teams.

QUALIFICATIONS

• Bachelor’s degree in Computer Science/Engineering (or equivalent experience)

• 6+ years of hands-on software development; 2+ years in technical leadership/ownership

• Mandatory skills: Python; C#/.NET Core; .NET MVC; JavaScript; React.js;Azure; MongoDB

• Proven experience designing and delivering scalable architectures (microservices, REST APIs), containerization (Docker/Kubernetes/AKS), and CI/CD (Azure DevOps)

• Strong data layer skills with MongoDB and SQL Server/Azure SQL (schema design, query optimization)

• Excellent problem-solving, debugging, and performance tuning across front-end and back-end

PREFERRED SKILLS

• A TypeScript, Node.js, or micro‑frontend experience; Redux/state management

• Messaging/caching (Azure Service Bus/Kafka, Redis)

• IaC (Terraform/Bicep), Git strategies, release automation

• Observability and quality tools (Splunk/ELK, Prometheus/Grafana, SonarQube); Bruno for API testing

• Integrations with enterprise systems (ERP/CRM) and experience in regulated environments

• FinOps awareness and DevSecOps practices

FIRST 12 MONTHS CHALLENGES

• Build working relationships with global stakeholders (Product, Security, Infra/Cloud, Data, ERP, RG/Discounts).

• Understand business goals for India BU; review current architecture, codebases, environments, and deployment processes.

• Confirm integration ownership: you are accountable for designing, delivering, and operating integrations with global systems.

• Define integration architecture standards (API contracts, auth, observability, error handling, SLAs).

• Run technical discovery with global teams; document integration specs for top use cases.

• Produce HLD/LLD, sequence/data flow diagrams, and a security model (RBAC, secrets management).

• Set non‑prod environments and test data strategies with global counterparts.

• Ship at least two production‑grade integrations, with monitoring, alerting, and rollback.

• Implement API versioning, backward compatibility, and error‑budget/SLI/SLOs.

• Conduct security reviews (OWASP) and close findings; integrate SonarQube into pipelines.

• Expand integration coverage (webhooks/events, batch jobs, reconciliation flows).

• Improve performance and resilience (caching, async/messaging, retries/circuit breakers).

• Partner with Security/Infra to meet compliance controls (ISO/DPDP); pass internal audits with zero critical findings.

• Publish integration playbooks/runbooks; hand over support procedures; mentor engineers on standards.

• Align next‑year roadmap with global stakeholders; lock quarterly milestones and capacity.
