Cover Letter Sample

I am writing to express my strong interest in the Senior Backend Engineer position on the Alerting squad at Grafana Labs. With extensive experience building and scaling distributed systems, I am excited about the opportunity to contribute to your open-source observability platform.

My background includes designing high-performance alerting systems and working on large-scale infrastructure, which aligns perfectly with your team's focus on scaling alert evaluation and delivery. I am particularly drawn to Grafana's commitment to open-source and collaborative culture.

I am a self-starter who thrives in remote environments and enjoys mentoring team members. I look forward to the possibility of driving impactful projects and ensuring reliability for your customers.

Thank you for considering my application. I am eager to discuss how my skills can contribute to Grafana Labs' continued success.

Possible Interview Questions

Describe your experience building and scaling distributed systems for high-throughput alert processing.

I have worked on systems that handle millions of events per second, using technologies like Kafka for ingestion and Go for processing. I implemented horizontal scaling with Kubernetes and optimized alert routing to reduce latency.

How do you approach designing a system that must be highly available and reliable?

I design for failure by using redundancy, graceful degradation, and robust monitoring. I also employ circuit breakers, retries, and fallbacks. For alerting, I ensure that the system can survive node failures without losing alerts.

Can you walk us through a project where you took ownership from ideation to operations?

I led the development of a new alert aggregation service. I started with requirements gathering, designed the architecture, implemented the code, set up CI/CD, deployed to production, and handled on-call support. I also documented the system and mentored junior engineers.

How do you handle on-call rotations and ensure system reliability?

I prioritize automation and monitoring to reduce manual intervention. I set up alerts for key metrics and have runbooks for common issues. During on-call, I triage incidents, communicate with stakeholders, and follow up with root cause analysis.

What is your experience with open-source contributions and community engagement?

I have contributed to several open-source projects, including fixing bugs and adding features. I also engage with the community by reviewing pull requests and participating in discussions. I believe in the value of open collaboration.

Senior Backend Engineer, Alerting

This is a remote opportunity and we would be interested in applications from Spain.

The Opportunity:

The Grafana Alerting squad operates at the core of the Grafana open-source project (link), and our mission is to provide the most in-depth way to let users manage their alerts. The backend-focused team works closely with customers and the Grafana Cloud teams to make Alerting work on-prem and at infinite scale in Cloud.

Our domain is quite large, so to get an idea of the kind of work we do, here are some projects we recently worked on:

Build distributed systems to scale alert ingestion and delivery of Prometheus-based alerts
Unify Alerting setup and delivery to work the same for Grafana and Prometheus-based alerts
Build distributed systems to scale alert evaluation of Grafana-managed alerts, reaching over 500 evaluations per second in production.

Grafana Alerting is trusted by major organizations worldwide, monitoring essential medical devices and critical infrastructure. We thrive on collective creativity and diverse perspectives, every team member is encouraged to contribute ideas that shape our product into a dependable tool.

What You’ll Be Doing:

Take an active role in influencing our roadmap and your own career objectives
Work with your team to deliver new features, then use the results to iterate and improve.
Drive projects from initial ideation all the way to operations once it is in the hands of customers
Embrace our open-source culture and contribute to other projects that may not directly fall within your team’s scope
Design, build, operate, and maintain critical systems, owning the reliability, performance, and availability
Be a part of your team’s on-call rotations and take ownership of the services you’re running
Mentor and support other team members, participate in design discussions and collaborate with the team
Learn new skills by gaining a deeper understanding of our cloud product and our customers and getting to know the codebase of a large distributed system

As we are remote-first and our engineering organization is largely remote, we provide guidance and meet regularly using video calls, so an independent attitude and good communication skills are a must.

What Makes You a Great Fit:

You are a motivated self starter with a bias towards action
You are customer focused
We build everything with our users in mind.
You have a passion for creating intuitive products that fit customers’ needs
Pragmatism: You are able to take on complex challenges and break them down to achieve short feedback loops: to analyze, design, and build modular solutions, deliver MVPs, gather data and feedback and then progress iteratively
Collaboration and communication: The smallest unit we have is a team. You’ll be working with your teammates in a fully remote setup. Good communication skills are a must
Solid experience with at least one programming language. We use Go, but if you have familiarity with Python, Java, C++, Rust or similar then that translates well
Some experience with delivering projects from gathering requirements, brainstorming ideas all the way to shipping a product to the customer’s hands in a self-driven way
Some experience with developing software that runs in the Cloud or some experience with systems engineering
Experience writing clean, robust, and performant software that is easily maintained by others

Compensation & Rewards:

In Spain, the compensation range for this role is EUR 82,988 – EUR 99,586. Actual compensation may vary based on level, experience, and skillset as assessed throughout the interview process. All of our roles include Restricted Stock Units (RSUs), giving every team member ownership in Grafana Labs’ success. We believe in shared outcomes—RSUs help us stay aligned and invested as we scale globally.

*Compensation ranges are country specific. If you are applying for this role from a different location than listed above, your recruiter will discuss your specific market’s defined pay range & benefits at the beginning of the process.
