Descripción de la vacante

Virtusa is seeking a Senior Lead Software Engineer to advance architectures for large-scale systems using Python and SQL. You will contribute to design judgments, guide teams, and build modular services with a focus on scalability and reliability.

The role requires hands-on cloud work (GCP or AWS) and strong RESTful APIs, WebSocket real-time components, and architectural discipline to avoid bottlenecks or single points of failure.

Formación

• Must have strong Python and SQL with production-grade proficiency.
• Solid relational databases fundamentals; schema design and query optimization.
• Hands-on cloud experience with at least one: Google Cloud Platform or AWS.
• 4+ years of professional software engineering experience.
• Experience with modular, well‑bounded components and low coupling.

Responsabilidades

• Contribute to architecture discussions and drive design decisions.
• Mentor junior engineers informally.
• Design scalable, modular software systems that solve real problems.
• Apply appropriate design patterns and best practices for reliability.

Senior Lead Software Engineer

Python, Agentic AI Cloud 4–10 Years Experience

Must-Have Skills

• Python strong, production-grade proficiency
• Databases solid relational/SQL fundamentals; schema design, query optimization, data modeling
• Cloud platform strong hands‑on experience with at least one of: Google Cloud Platform or AWS
• 4+ years of professional software engineering experience
• Design Architecture Thinking
• Strong grounding in modular design clear separation of concerns well-bounded components/services low coupling / high cohesion
• Ability to design systems that scale horizontally statelessness where it matters partitioning/sharding strategy load distribution avoiding single points of contention
• Working fluency in core design patterns and principles and knowing when to apply vs. avoid them
• API & Real-Time Integration Best Practices
• Strong grasp of RESTful API design resource modeling versioning pagination idempotency for retries, proper status codes/error contracts
• Practical experience with WebSocket-based real‑time communication — connection lifecycle management, reconnection/backoff strategy heartbeat/keep‑alive handling and graceful degradation when a socket drops
• Understands tradeoffs between REST WebSockets and event‑driven/streaming integration patterns and picks the right one for the use case
• Designs integrations for observability and resilience structured logging timeouts circuit breakers and clear failure modes rather than silent drops

Highly Desired

• Java working knowledge candidates comfortable in both Python and Java are ideal
• Healthcare domain experience prior work on healthcare health‑tech or health‑data platforms is a strong plus
• ML/AI exposure enough to reason about model outputs, confidence, and integration patterns

Role Expectations by Level

Senior Engineer

Contributes to architecture discussions; applies design patterns appropriately

Mentors junior engineers informally

Nice to Have

• Deep AI/ML research background not required this is an application/systems engineering role that touches AI tooling not a research role

What We're Really Screening For

• Strong in Python SQL databases as a baseline
• Solid architectural instincts modular scalable design not just make it work
• Comfortable or curious about Java
• Open to learning already exposed to agentic AI MCP server patterns
