Job Description
Senior Fullstack Engineer building onboarding, lifecycle, and checkout systems for Nivoda’s global jewellery marketplace. Improving activation, conversion, and retention through event-driven services and experimentation.
Responsibilities:
- Own and evolve backend services behind onboarding, verification, activation, and the sign-up-to-purchase funnel
- Design and build event-driven, workflow-orchestrated systems that continuously evaluate account states and trigger actions
- Integrate with identity verification, KYB/KYC, and fraud/risk providers
- Ensure integrations are resilient, well-monitored, and fail safely
- Handle credit and payment data responsibly in personalization and reactivation logic
- Design and run experiments with guardrail metrics
- Write SQL and work directly in Snowflake or similar warehouses for cohort and funnel analysis
- Diagnose time-to-activation, time-to-churn, and other funnel problems
- Define problems without established playbooks and develop solutions
- Use AI agents to accelerate building and testing funnel and lifecycle services
- Review and verify AI-assisted analytical queries and generated output before use
- Evaluate AI-generated messaging, reactivation copy, and churn-cause suggestions critically
- Collaborate with Product, Data, and Risk in the Growth Pod
Requirements:
- 4–7 years of experience
- Strong backend product engineering experience, most likely in TypeScript/Node.js
- Ownership of funnel-critical, production services
- Hands-on experience with event-driven architectures and workflow orchestration
- Genuine experimentation rigor, including guardrail metrics and distinguishing real results from noise
- Strong SQL and warehouse fluency, including Snowflake or similar
- Confidence performing cohort and funnel analysis independently
- Comfort using AI agents to build and test software and draft and sanity-check analytical work
- Judgement to catch subtle errors in AI-generated output
- High tolerance for ambiguity
- Practical fluency evaluating AI-generated copy, messaging, or root-cause suggestions
- Nice to have: experience with identity verification, KYB/KYC, fraud and risk providers
- Nice to have: experience handling credit, payment, or sensitive financial data
- Nice to have: experience in a high-growth marketplace or fintech environment
- Nice to have: familiarity with Temporal, AWS Step Functions, Kafka, or similar tooling
