Dear Hiring Team,

I am writing to express my strong interest in the Senior Software Engineer - Backend - Growth Platform position at Kraken. With over 5 years of experience building scalable backend systems and developer platforms, I am excited about the opportunity to contribute to Kraken's mission of accelerating global crypto adoption.

In my previous role, I designed and maintained SDKs, CLIs, and APIs that empowered multiple engineering teams to ship features faster and more reliably. I thrive on creating elegant developer experiences and have a proven track record of improving engineering workflows through automation and tooling.

I am particularly drawn to Kraken's focus on ownership, experimentation, and craftsmanship. I am confident that my technical skills and passion for crypto align well with the needs of your Growth Platform team.

Thank you for considering my application. I look forward to the possibility of discussing how I can contribute to Kraken's growth.

Sincerely,
[Your Name]

Can you describe your experience building and maintaining SDKs or CLIs for internal teams? What were the key design decisions?
I have built an internal SDK for a microservices architecture that standardized authentication and logging. Key decisions included using a plugin-based architecture for extensibility, providing clear documentation with examples, and ensuring backward compatibility through semantic versioning.
How do you approach designing scalable backend systems that handle millions of users? Can you give an example?
I designed a user engagement service that processed events at high throughput. I used event-driven architecture with Kafka, implemented caching with Redis, and designed the database schema for horizontal sharding. Regular load testing and monitoring ensured performance.
Describe a time when you improved engineering workflows or deployment efficiency through automation. What was the impact?
I automated the CI/CD pipeline by integrating code linting, testing, and deployment scripts. This reduced deployment time from 30 minutes to 5 minutes and lowered manual errors, allowing the team to release more frequently.
How do you ensure reliability and observability in distributed systems? What tools and practices do you use?
I implement comprehensive logging, metrics, and tracing using tools like Prometheus, Grafana, and Jaeger. I also set up alerting based on SLOs and conduct post-mortems for incidents to improve system resilience.
How do you mentor other engineers and advocate for engineering excellence? Provide a specific example.
I organized weekly tech talks on best practices like code reviews and testing. I also paired with junior engineers on complex features, guiding them through design patterns and code quality standards, which improved team velocity and code maintainability.

  • Nice to have: familiarity with React or React Native, especially when building front-end SDKs or shared components.

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

Nice to haves

  • Experience building internal developer platforms or frameworks used across multiple teams.

  • Background in observability, reliability engineering, or service instrumentation.
