The Analysis and Experimentation team is responsible for building and maintaining a scalable, well‑governed analytics and experimentation ecosystem that enables Kraken’s product and platform teams to make confident, data‑driven decisions. Our mission is to ensure that product data and experimental results are accurate, reliable, and actionable, forming a trusted foundation for learning, iteration, and decision‑making across the company.

As a Frontend Engineer on the Analysis and Experimentation team, you will play a central role in powering Kraken’s experimentation program. You will own and evolve the frontend foundations that enable high‑quality experiment instrumentation, consistent metric collection, and trustworthy analysis. Your work will directly impact how product teams design experiments, measure outcomes, and learn from user behavior.

The opportunity:

• Implement high‑impact experiments and increase the throughput of the experimentation program to directly drive revenue.
• Support Kraken’s experimentation platform by enabling reliable exposure logging, metric collection, and experiment guardrails on the frontend.
• Partner with Data Engineering and Analytics to ensure experimental data aligns with canonical definitions and supports statistically sound analysis.
• Implement validation, monitoring, and alerting to proactively detect issues in experiment and product event data.
• Document and evangelize best practices for experimentation and analytics implementation, creating clear guidance for product and engineering teams.
• Collaborate with product teams to support experiment design needs, including metric feasibility, instrumentation tradeoffs, and implementation patterns.
• Improve and simplify event data flows to reduce redundancy, improve transparency, and lower long‑term maintenance costs.
• Contribute to the evolution of Kraken’s experimentation frameworks, enabling faster iteration while preserving analytical rigor.

Skills you should HODL:

• 5+ years of experience in frontend development with strong expertise in React.js, React Native and TypeScript.
• Strong understanding of frontend data instrumentation, event modeling, and client‑side data flows.
• Experience supporting experimentation or A/B testing systems, including exposure tracking and metric instrumentation.
• Proven ability to debug and resolve data quality issues across complex frontend applications.
• Experience collaborating across product, engineering, and data teams to deliver shared platforms or standards.
• Clear written and verbal communication skills, especially around technical tradeoffs and data correctness.

Nice to haves:

• Familiarity with experimentation methodologies, statistical concepts, and common pitfalls in experiment analysis.
• Experience with analytics or experimentation tools (e.g., internal platforms, homegrown frameworks, or third‑party solutions).
• Hands‑on experience with frontend testing frameworks and modern build pipelines.
• Exposure to large‑scale analytics or experimentation infrastructure.
• Understanding of cryptocurrency, blockchain technology, and decentralized applications.
