Job Description

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.
