Job description

Head of Backend

Function: Engineering - Platform & Backend

Location: A-8A, Knowledge Boulevard, Sector 62, Noida, Uttar Pradesh (on-site / hybrid)

Reports to: CTO / VP Engineering & Product Development

Direct reports: 20+ backend engineers, tech leads and engineering managers across product squads

Experience: 12+ years building backend systems, including 4+ years leading engineering teams

The role:

We are hiring a Head of Backend Engineering to own the architecture, delivery and operational health of every server-side system at Delta6Labs. You will lead a group of 20+ backend engineers, tech leads and managers across product squads, and report directly to the CTO / VP Engineering & Product Development as part of the engineering leadership team.

Qualification:

Qualification: B.E. / B.Tech / M.C.A. in Computer Science, Engineering or a related discipline. Equivalent practical experience considered.

What you will own:

• Own the backend architecture across all Delta6Labs platforms - exchanges, wallets, trading systems, and white-label deployments and hold a coherent technical vision that survives client-specific pressure.
• Make and document the consequential decisions: service boundaries, data ownership, synchronous versus event-driven communication, consistency models, and where we accept coupling in exchange for correctness.
• Run a lightweight architecture review practice - design docs, RFCs, a technical decision record, so choices are debated before they are shipped and understood long after.
• Lead the design of high-throughput, low-latency paths - order matching, order-book and market-data distribution over WebSocket, risk checks and liquidity routing with explicit latency and throughput budgets.
• Own correctness-critical subsystems: the double-entry ledger, balance and fee computation, settlement and reconciliation, idempotency guarantees, and exactly-once semantics where money is involved.
• Own third-party integration architecture across KYC/AML (SumSub, Veriff), blockchain analytics (Chainalysis), fiat and payment rails, market-data vendors and trading terminals such as MetaTrader 5.
• Design for multi-tenancy - configuration-driven white-label deployments, tenant isolation, and the ability to ship a fix to one client without endangering the rest.
• Own backend delivery across squads, scoping, estimation, sequencing and commitment - and be accountable for predictable, high-quality releases against client and product timelines.
• Set and enforce engineering standards: code review, testing expectations, API design and versioning, error contracts, documentation, and definition of done.
• Partner closely with the Head of QA on testability, contract testing and release gating; with DevSecOps on CI/CD, infrastructure and deployment; and with Product on what is actually buildable when.
• Break down and de-risk large programmes into shippable increments, with migration and rollback plans that have been thought through before they are needed.
• Own technical debt as a managed portfolio, visible, prioritised and funded, rather than a backlog everyone gestures at.
• Stay close enough to the code to review critical designs and pull requests, debug a production incident credibly, and keep the respect of your strongest engineers.

Team leadership and development:

• Lead, coach and grow a backend organisation of 20+ engineers, build the tech-lead and engineering-manager layer so the function scales beyond your own bandwidth.
• Define career ladders, competency frameworks, goal setting and performance reviews; develop your strongest engineers into architects and leads, and address underperformance honestly and early.
• Build a culture of engineering rigour and candour where designs are challenged on merit, incidents are learning material rather than blame material, and people raise risk early without fear.
• Act as a senior technical voice with clients and stakeholders, architecture walkthroughs, and security or audit conversations.

What you must bring:

• 12+ years building and operating production backend systems, including 4+ years leading engineering teams, with direct experience managing a team of ten or more.
• Deep distributed-systems expertise: microservices, event-driven architecture, message queues and streaming (Kafka, RabbitMQ or similar), consistency and consensus trade-offs, idempotency, and designing for partial failure.
• Strong hands-on engineering depth in at least one of Node.js/TypeScript, C++ or Python, Postgres, MongoDB with the ability to reason credibly across the others.
• Demonstrated ownership of a high-throughput, low-latency or high-transaction-volume production platform in fintech, payments, trading, exchange or comparable domains.
• Real database expertise: relational modelling and query performance at scale (PostgreSQL or MySQL), caching (Redis), and appropriate use of time-series, analytical
