Senior Performance Engineer - DevOps

At Beekeeper, your mission will be to drive platform performance and efficiency, delivering tangible improvements to API, database, and network performance.

With over 1 million monthly active users and billions of API requests processed, you will play a key role in enhancing our observability and using these insights to optimize our platform. This includes tackling challenges in networking, database architecture, query optimization, caching, and microservices design. You won’t just surface issues – you will own them, proactively diving into different domains, languages, and technologies to implement solutions.

As a key member of our amazing DevOps team, you will work with our modern cloud-native infrastructure and best-in-class tooling to realise these goals.

If you thrive on making a measurable impact, are unafraid to explore unfamiliar technologies, and enjoy collaborating with other teams, this is the ideal role for you!

Your responsibilities

• Optimize Database Performance: Improve the performance and scalability of our databases through identifying and improving query hotspots, making schema improvements, and tuning the underlying systems
• API Performance Optimization: Enhance API performance by reducing end-to-end request latency and increasing throughput through techniques like tuning worker pools, connection pools, caching, and leveraging tools like ProxySQL
• Code-Level Insights: Analyze, read, and modify code across various services to identify and fix performance bottlenecks
• Performance Monitoring: Design and maintain dashboards that provide actionable insights into performance across our systems
• Collaborative Problem Solving: Partner with engineering teams to investigate and resolve platform-wide performance issues
• Mentorship: Share your expertise with the engineering team, teaching best practices for database performance, profiling, and scalable system design

What we look for in you

• Collaborative Attitude: A team player eager to collaborate across engineering teams
• Proven Experience: 5+ years of engineering experience with a strong focus on performance and system optimization
• Database Expertise: Deep understanding of database internals and optimization techniques, particularly for MySQL and PostgreSQL
• Linux and Networking Expertise: Strong knowledge of Linux systems and networking (e.g., TCP/IP, load balancing, DNS), with the ability to troubleshoot complex issues
• Code Fluency: Solid ability to read and modify code in languages such as Python, Java, or other backend-oriented programming languages
• Kubernetes Experience: Practical experience with Kubernetes, including understanding its impact on performance and scalability
• Microservices Observability Expertise: Practical experience with tracing tools and optimising microservices architectures
• Performance Profiling Mastery: Hands-on experience with tools like eBPF, flame graphs, and other profiling techniques inspired by Brendan Gregg’s methodologies
• Cloud Platforms: Familiarity with cloud services (AWS, GCP) and their database offerings (e.g., RDS, managed PostgreSQL/ClickHouse)

Bonus Points

• ​​Global Network Optimization: Experience optimizing global network performance using cloud tooling to leverage edge caching, early TLS termination, HTTP protocol optimisation (e.g. HTTP/2/3 or QUIC), etc.
• Infrastructure-as-Code Expertise: Familiarity with tools like Terraform for automating and managing infrastructure deployments
• Open Source Contributions: Contributions to open-source projects, especially in the database, performance, or observability domains

Our technology stack

• We run on top of AWS and GCP across 4 regions
• We believe in Infrastructure as Code and manage our cloud infrastructure using Terraform via Spacelift
