Software Development Engineer - Multi-Domain Product Engineering

About The Role Most engineering roles give you one product, one domain, and a ticket queue. This one is different. At Techdome, you will work directly on four live, revenue-generating products — an AI-powered recruitment platform, a healthcare management portal, a stock trading & investment platform, and fintech payments infrastructure. You will not be a cog in a large engineering org. You will be one of the engineers who owns the architecture, shapes the product, and ships features that real users depend on. If you are 2–6 years into your career and want to compress a decade of domain exposure into the next two years — this is where you do it.

What You Will Do

• Take full ownership of features — from scoping and system design through development, testing, deployment, and iteration
• Build fast, responsive frontend interfaces with React.js and rock-solid backend services with Node.js and Express.js
• Design REST APIs, backend microservices, and third-party integrations that are built to scale and easy to maintain
• Model and optimize data across MongoDB, MySQL, and PostgreSQL — with Redis handling caching, queuing, and real-time data layers
• Engineer payment systems end-to-end — gateway integrations (Stripe, Razorpay, PayPal, Braintree), webhook pipelines, reconciliation flows, payout workflows, and fault-tolerant retry logic built to PCI-DSS standards
• Build trading platform features that demand precision — order management systems, real-time market data feeds via WebSockets and SSE, portfolio and watchlist modules, and integrations with brokerage APIs like Zerodha Kite, Upstox, and Angel One
• Develop healthcare portal modules that handle sensitive workflows at scale — patient management, EHR data flows, appointment scheduling, hospital billing and claims, and pharmacy/lab integrations via HL7/FHIR APIs
• Wire AI and ML APIs into recruitment workflows — automated screening pipelines, interview scoring engines, evaluation logic, and recruiter-facing dashboards
• Handle financial and patient data with the security it deserves — tokenization, encryption, and awareness of PCI-DSS and HIPAA compliance requirements
• Ship with confidence using CI/CD pipelines, Git-based workflows, and Agile/Scrum practices
• Leverage AI-assisted development tools — GitHub Copilot, Cursor, Claude — as a genuine force multiplier in your daily workflow

What You Bring

• 2–6 years of experience as a Full Stack Developer, Software Engineer, or Product Engineer
• Strong command of React.js on the frontend and Node.js with Express.js on the backend
• Solid working knowledge of MongoDB, MySQL, or PostgreSQL — and the ability to write queries that perform well at scale
• Proven, production-level experience with payment gateway integrations — Stripe, Razorpay, PayPal, or Braintree
• Hands-on experience shipping features on SaaS or product-based platforms — fintech, healthtech, trading, or similar domains strongly preferred
• Working knowledge of secure data handling — tokenization, encryption, PCI-DSS and HIPAA compliance awareness
• Strong grasp of REST API design, webhook architecture, and system design fundamentals
• Experience with Redis or equivalent caching systems — especially for real-time or high-throughput use cases
• Collaborative development practices — Git workflows, code reviews, and team-oriented engineering habits
• Comfort operating in an Agile/Scrum environment with fast iteration cycles

What Will Set You Apart

• Experience building or contributing to stock trading platforms — order books, live price feeds, brokerage API integrations (Zerodha Kite, Upstox, Angel One)
• Hands-on work with real-time data pipelines — WebSockets, Server-Sent Events, or Kafka for streaming market data
• Experience integrating AI/ML APIs or building LLM-powered product features
• Exposure to healthcare data standards — HL7, FHIR, or ABDM (India)
• Cloud infrastructure experience — AWS, Azure, or GCP
• Containerization and orchestration — Docker, Kubernetes, or microservices patterns
• CI/CD tooling — GitHub Actions, Jenkins, or GitLab CI
• Automated testing habits — Jest, Mocha, or similar
• Exposure to agentic AI frameworks — LangChain, CrewAI, or similar
• A background in startup or product-led engineering environments — where ownership was real and timelines were tight

Why Techdome We are a bootstrapped, profitable technology company with 5+ years of product engineering across AI hiring, healthcare, trading, and fintech. We do not have layers of management slowing things down. We do not hire for headcount. We hire engineers who want to build things that matter — and we give them the room, the trust, and the ownership to do exactly that. You will work across domains that most engineers spend an entire career trying to enter — payments, healthcare, trading, and AI — all within one role, one team, and one company that is growing because the products work. We pay for outcomes. Not titles. Not tenure.
