Senior Backend Engineer (L3) - Trading

You will own significant parts of the Client Trading Engine and Pricing Engine end-to-end — design, build, ship, and operate. This is a hands-on senior IC role with high ownership and accountability - the pricing logic you write today shows up in tomorrow's revenue numbers.

We're specifically looking for someone with a trading background — you've built systems where a quote had to be correct and fast, and where a bug meant real money. Think a crypto exchange, brokerage, or trading platform (CoinDCX, Groww, CoinSwitch Kuber, or similar).

Key Responsibilities

• Design, build, and operate services across the trade path — quoting, pricing, spread application, and trade lifecycle management.
• Own features end-to-end: scoping, technical design, delivery, rollout, and the operational health of what you ship.
• Drive work to closure with Product, Design, and Operations. You are accountable for adoption, not just delivery.
• Act as a product engineer — scope a problem statement, understand its product impact, and take the hard prioritisation calls.
• Build for correctness and latency on a live client trade path. Understand and weigh trade offs.
• Instrument what you build — logging, metrics, and alerting that make the behaviour of the trade path predictable in production.
• Design for failure: retries, idempotency, and safe recovery when a downstream dependency misbehaves.
• Expose trading capability across surfaces — GUI, public API, and conversational AI — with clean, stable contracts.
• Raise the bar through code review and design feedback, and mentor L1/L2 engineers on the team.
• Build a healthy engineering-excellence and tech-debt backlog — surface the right items, work with the EM on a resolution plan, and drive them to closure.
• Participate in on-call, respond to incidents with urgency, and turn post-mortems into durable fixes.
• Work directly with product and the Hedging team to connect what you build to Total Payment Volume and gross revenue.

What we are looking for

Must-haves:

• 4–6 years of experience building and operating production backend systems.
• A trading background — you've worked at a trading company, exchange, or brokerage and have built systems on a live trade or order path (e.g. CoinDCX, Groww, CoinSwitch Kuber, or similar).
• Strong fundamentals in system design, data modelling, and API design, with practical experience in distributed systems.
• Solid command of object-oriented programming principles and low-level design patterns.
• Solid production engineering instincts — observability, debugging complex systems, performance tuning, and incident response.
• Comfort with abstract, ambiguous problems — you can turn a vague mandate into scoped, sequenced deliverables without waiting for someone to specify it for you.
• Hands-on and high agency. You find the important problem and go solve it rather than waiting to be assigned it.
• Heavy AI user. You use AI coding tools with real technique and get materially more done because of it.
• Data-driven, and a clear written communicator — we are async-heavy and globally distributed.

What helps you stand out:

• Experience with pricing, quoting, or spread engines specifically.
• Experience with FX, multi-currency systems, or cross-border payments.
• Experience with market data, order books, or market microstructure.

What Success Looks Like

• The services you own on the trade path are reliable, well-tested, and observable — issues are caught before clients notice them.
• You ship complex features end-to-end from technical design to execution, delivery and adoption.
• The team moves faster because of your code reviews, documentation, and technical judgment.
• L1/L2 engineers around you grow measurably faster.
• You become a go-to engineer for the trade path.
• You raise the bar for the Trading team.

What We Offer

• Competitive salary and benefits package.
• Equity in a rapidly growing company.
• Opportunity to work in a fast-paced startup at the forefront of fintech innovation.
• Opportunity to make a significant impact on global financial infrastructure.
• Collaborative work culture with emphasis on personal and professional growth.

We are committed to building a diverse and inclusive workplace. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status.
