- Translate product requirements into technical designs, data models, state machines, service boundaries, implementation plans and test strategies.
- Take ownership of difficult production workflows involving payments, mandates, broker or custodian integrations, order lifecycles, asynchronous callbacks, data freshness and reconciliation.

- Evaluate and apply AI tools and techniques where they create real leverage.

What We Are Looking For

- 6+ years of professional software-engineering experience, including meaningful ownership of production backend systems.
- Strong Python experience across APIs, services, data models, queues/jobs, integrations and tests.
- Strong React Native experience, or enough mobile-platform fluency to lead the backend/mobile contract and review React Native code.
- Experience leading or mentoring a team of approximately 10 developers, formally or informally.
- A track record of shipping reliable products in a startup, fintech, wealth-tech, payments, brokerage or other high-trust workplace.
- Strong understanding of relational databases, API design, asynchronous processing, event-driven workflows, caching, queues, webhooks, idempotency and observability.




- Solid infrastructure and DevOps experience, preferably on AWS or GCP : CI/CD, infrastructure-as-code, containerisation, secrets management, monitoring, alerting, backups and incident response.
- Practical knowledge of fintech security and compliance: access control, encryption, audit trails, data privacy, secure SDLC, vulnerability management and audit readiness.
- Strong code-review judgement: you identify correctness, security, performance and reliability risks without blocking progress unnecessarily.
- Hands-on AI experience : foundation-model APIs, AI-enabled workflows, retrieval or tool-calling, evaluation and guardrails, or AI-assisted development.
- Clear written and verbal communication, a coaching mindset, and high ownership from design through deployment and support.

Strong Differentiators

- Built or operated financial products involving money movement, investment orders, portfolios, broker or custodian integrations, market data or reconciliation.
- Worked with regulated fintech security, compliance or audit programmes in India or another major financial market.
- Led a team through a meaningful scale-up in codebase, traffic, product surface or engineering headcount.
- Designed systems that safely handle pending, retryable, failed, duplicate and reconciled states.
- Built customer-facing mobile products in React Native alongside Python services.
- Hired engineers, established engineering rituals or managed delivery across multiple teams.
- Worked in a zero-to-one environment and created structure where it did not yet exist.
