Data Scientist - Growth (Europe) in London

About Nivoda

Nivoda’s growth trajectory has skyrocketed over the past 12 months, and we continue to expand across new regions at an unprecedented pace. Our DNA centers on understanding our customers' needs and offering them a seamless experience. With a growing team based in major cities worldwide, including London, New York, Hong Kong, and Mumbai, Nivoda is becoming the go‑to marketplace for the global jewelry industry. We are bold, innovative, and relentless in our pursuit of excellence as we transform an industry steeped in tradition.

About the Role

We are building our data science capability from the ground up, and this is a rare opportunity to be the founding data scientist embedded within our Growth team. You will own the analytical agenda for growth — from onboarding funnel analysis and top-of-funnel acquisition through to activation, product uptake, and revenue expansion — and for delivering insights that drive meaningful business outcomes. This role sits at the intersection of data engineering, experimentation, and growth strategy. You will work autonomously, partnering closely with growth product managers, engineers, and marketing, and you will have the freedom to build the infrastructure and culture of data-driven decision-making.

What You'll Do

• Experimentation & A/B Testing: Design, build, and own a robust A/B testing and experimentation framework for the growth function. Define metrics, set up holdout groups, run significance tests, and communicate results with clarity to both technical and non-technical stakeholders. Identify opportunities for rapid iteration and champion a test-and-learn culture across the growth pod.
• Data Infrastructure & Pipelines: Build and maintain scalable data pipelines and databases that support real-time and near-real-time growth analytics. Develop ETL pipelines (e.g. Python-based) and ensure reliable, clean data flowing into dashboards and models. Collaborate with the Head of Data Engineering to align on tooling, architecture, and best practices.
• Growth Analytics: Analyse user behaviour across the full funnel — acquisition channels, onboarding, conversion, engagement, and churn. Build models and dashboards that surface actionable insight for the growth and marketing teams. Work closely with AI tools and emerging technologies; bring demonstrable experience of AI-native workflows to the team.
• Cross-Functional Partnership: Act as the primary data partner for growth PMs, engineers, and marketing stakeholders. Translate complex analyses into clear narratives and recommendations for senior leadership. Over time, help define what a best-in-class data science function looks like and contribute to building it.

What You'll Need

• Master’s degree in a quantitative discipline (e.g. Statistics, Computer Science, Mathematics, Engineering) or equivalent practical experience.
• 4 - 6+ years of experience as a data scientist, ideally within a growth pod or growth-focused team at a scale-up (Series B through pre-IPO).
• Hands-on experience building and running A/B testing frameworks from scratch.
• Strong engineering fundamentals — comfortable building ETL pipelines, data models, and production-quality analytical code (Python preferred).
• Experience working with complex, cross-functional data in a fast-paced startup or scale-up environment.
• AI-native: actively using AI tools in your day-to-day workflow and able to speak to the tangible impact this has had.
• Comfortable operating autonomously with a builder mindset — there is no established data science function to lean on.

Preferred Qualifications

• Experience at a marketplace business (two-sided platforms with real-time supply/demand dynamics).
• Background as a growth analyst or in a growth PM-adjacent role before moving into data science.
• Prior experience working in Series B–D high-growth companies where you’ve had to build, not just maintain.

What We Offer

• Flexible working hours and a vibrant company culture.
• Remote work.
• Plenty of opportunities for growth and learning.
• Unlimited holiday allowance.
• Chance to join and contribute to a company during its exponential expansion phase.
