Technical Lead / Senior Software Development Engineer

Position: Technical Lead / Senior Software Development Engineer

Location: New Town, Kolkata (West Bengal)

Overview

We’re looking for a hands-on technical lead who can architect, guide, and build high-quality systems. You’ll lead by design and example — helping the team develop software that’s modular, maintainable, and interoperable.

Our stack spans Node.js, React, MongoDB, healthcare data models, and AI-powered analytics. But we’re not tied to any one language — we’re looking for someone who can bridge stacks, not guard them.

What You’ll Do

• Lead technical design discussions and translate specifications into reliable implementations.
• Review and mentor developers on writing maintainable, low-coupled, reusable modules.
• Design integrations across heterogeneous systems (e.g., Java to Node.js bridges, FHIR/HL7 data pipelines).
• Improve code quality, structure, and consistency across services.
• Build internal tools, SDKs, or shared libraries that promote reusability and standardization.
• Own system-level performance, scalability, and resilience.
• Collaborate with PMs, QA, and architects to shape deliverables and timelines.
• Identify risks, propose architectural improvements, and simplify complex systems.
• Help nurture a learning culture — reviewing code, organizing discussions, and documenting patterns.

What We Value

• Architectural clarity: ability to design cohesive systems that don’t rely on accidental behavior.
• Strong fundamentals: data structures, concurrency, caching, message queues, and network protocols.
• Pragmatic leadership: lead by building and improving, not just by managing.
• Cross-stack fluency: capable of jumping between React UI, Node.js backend, and system-level integrations.
• Hands-on mindset: can roll up sleeves to debug or optimize production code.
• Mentorship: ability to guide junior developers to write from specifications, not from samples.
• Curiosity: explores new tech, understands why something works before using it.

Must Have

• 6+ years of software engineering experience, with at least 2 in a technical leadership or system design role.
• Strong command of JavaScript/TypeScript and Node.js ecosystem.
• Understanding of distributed systems, async processing, and service-oriented design.
• Experience with databases (MongoDB, PostgreSQL) and cloud platforms (AWS/GCP/Azure).
• Strong debugging, profiling, and code review skills.

Nice to Have

• Exposure to healthcare data models (FHIR, HL7, EHR integrations).
• Experience designing modular frameworks, SDKs, or internal developer tools.
• Interest in AI integration and healthcare analytics workflows.
• Active GitHub or portfolio demonstrating design/architecture thinking.
