Senior Developer / Tech Lead

Location : Remote (Head office in Mumbai)

Employment Type : Full-time

Experience : 6+ years

Notice Period : Immediate to 30 days

What You Will Own :

- Lead backend architecture and implementation for core investment, portfolio, analytics and platform capabilities.

- Build and maintain production systems in Python, including APIs, business workflows, integrations, background jobs, webhooks, reconciliation and operational tooling.

- Work closely with React Native engineers to define clean API contracts, predictable states, useful error handling and maintainable mobile integrations.

- 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.

- Establish practical engineering standards for code quality, testing, observability, documentation, release discipline and incident response.

- Review code consistently and thoughtfully; merge changes when they meet the required quality, safety and maintainability bar.

- Mentor junior developers through design reviews, pairing, code reviews, debugging and clear technical feedback.

- Lead technical decomposition and delivery for projects across mutual funds, Indian equities, U.S. stocks, wealth aggregation and financial analytics.

- Partner with Product, Design, Operations, Compliance and external technology providers to make sound trade-offs between speed, quality, risk and cost.

- Improve the developer experience : local setup, environments, CI/CD, test feedback, debugging workflows, documentation and deployment confidence.

- Build a security-minded engineering culture appropriate for a fintech product handling sensitive identity, financial and investment data.

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

- Help define the future engineering organisation, hiring plan, technical roadmap and operating cadence as the company grows.

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 environment.

- 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.
