Key Skills

Full-stack Development TypeScript Rust Growth Engineering Crypto KYC Data-driven Remote Work Scalable Systems A/B Testing

I am excited to apply for the Senior Software Engineer position on the Growth Product team at Kraken. With over 5 years of experience building and maintaining production systems at scale, I have a strong foundation in full-stack development using TypeScript and Rust. I am particularly drawn to this role because it sits at the intersection of product, marketing, and infrastructure, where I can directly impact user acquisition and engagement.

In my previous role, I led the development of onboarding and KYC flows that improved conversion rates by 20% through A/B testing and data-driven iterations. I thrive in collaborative, remote environments and am committed to engineering excellence and measurable outcomes. I am eager to bring my technical skills and passion for crypto to Kraken's mission of accelerating global adoption.

Thank you for considering my application. I look forward to the opportunity to contribute to the Growth Engineering team and help build the future of crypto.

Can you describe a time when you used data-driven experimentation to improve a user onboarding flow?
In my previous role, I noticed a high drop-off rate during the KYC process. I implemented A/B testing to compare a simplified form with a multi-step wizard. The wizard reduced drop-off by 15%, so we rolled it out to all users. I used analytics to track each step and iterated based on user behavior.
How do you approach designing a scalable system for handling global traffic spikes?
I focus on horizontal scaling, caching, and asynchronous processing. For a recent project, we used a message queue to decouple user registration from email verification, and we added CDN caching for static assets. Load testing helped us identify bottlenecks before launch.
Explain how you would build a feature to re-engage dormant users. What metrics would you track?
I would start with a cohort analysis to understand why users churn. Then, I'd design a personalized email or push notification with a special offer. Key metrics would include open rate, click-through rate, and percentage of users who fund their account within 7 days. I'd run an A/B test on messaging and timing.
How do you ensure code quality and maintainability in a fast-paced growth environment?
I advocate for strong code reviews, automated testing, and clear documentation. I also prioritize modular design so features can be easily iterated. In growth teams, it's important to balance speed with quality, so I often use feature flags to release incrementally and roll back if needed.
Describe your experience with TypeScript and Rust. Which do you prefer for which use cases?
I have used TypeScript extensively for full-stack web development, especially with Node.js and React. Rust I've used for performance-critical services like a real-time order matching engine. TypeScript is great for rapid prototyping and frontend work, while Rust excels in systems where memory safety and speed are paramount.

Proof of work

The team

The Growth Engineering team builds the experiences that connect people to our ecosystem for the first time — and keeps them coming back. We design and ship the systems behind our marketing funnels, signup and KYC flows, and the key engagement features that help new users fund their accounts and explore our products. It’s a team with direct influence on company growth, global reach, and user engagement at scale. Our products serve millions of users globally.

How We Work

  • We give engineers ownership and trust them to ship high-impact work with craftsmanship and accountability.

  • We move quickly, experiment often, and learn fast from data and feedback.

  • We work asynchronously across time zones, supporting each other with open communication and shared goals.

Why This Role Matters

Every feature you build will have a visible impact on how people discover, trust, and engage with our products globally. The Growth Engineering team operates at the intersection of product, marketing, and infrastructure — turning ideas into measurable results. If you’re an engineer who enjoys solving business problems through code and believes engineering excellence drives growth, this role is built for you.

The opportunity

As a Senior Software Engineer within Growth Product team, you’ll take on complex, high-impact problems that blend product thinking and engineering excellence. You’ll work across web and mobile platforms, collaborating with design, data, and product teams to deliver features that drive measurable business outcomes. This is an ideal role for engineers who use their technical skills to create real-world impact — translating high-level business goals into engineering solutions that improve activation, retention, and monetization worldwide.

  • Partner with product managers, designers, and analysts to identify growth opportunities and turn them into high-quality, data-driven engineering solutions.

  • Implement reusable services and components that power marketing campaigns, onboarding, KYC, and first-funding experiences across web and mobile.

  • Collaborate on distributed systems that handle large volumes of global traffic while maintaining high performance and reliability.

  • Participate in design and architecture discussions, balancing user impact, scalability, and maintainability.

  • Measure, experiment, and iterate — using data and experimentation frameworks to understand what drives user behavior.

  • Uphold and improve engineering standards, performance, and security practices across the stack.

Skills you should HODL

  • 5+ years of software engineering experience, including building and maintaining production systems at scale.

  • Proficiency in building full-stack applications using one of the following: TypeScript, Rust, Go, Python, or Ruby, and React or React Native.

  • Understanding of distributed systems, performance optimization, debugging, and secure software design.

  • Familiarity with infrastructure and tooling such as Docker, Kubernetes, Terraform, MySQL/MariaDB, Redis, or GitLab CI/CD.

  • A product mindset — you care about how your work moves key metrics, not just about the code itself.

  • Ability to operate autonomously in a globally distributed, remote-first environment.

Nice to haves

  • Experience with A/B testing, analytics instrumentation, or experimentation platforms.

  • Background in growth engineering, user funnels, lifecycle, or conversion optimization.

  • Familiarity with data analysis tools or experimentation frameworks.
