Senior Backend Engineer - Databases Pyroscope | UK | Remote

Grafana Labs is the company behind Grafana Cloud, the fully managed observability platform trusted by more than 10,000 organizations to ensure reliability, resolve incidents faster, and optimize telemetry at scale. Built on open source and open standards and designed for interoperability across any stack, Grafana Cloud brings AI to observability and observability to AI, giving teams (and their agents) unified visibility so they can see, understand, and act on all their disparate data, wherever it lives, and move at the speed of their ambitions. Customers, including Anthropic, Bloomberg, NVIDIA, Microsoft, and Salesforce, rely on Grafana Labs. We are a 100% remote company with team members across 40+ countries, backed by leading investors including Lightspeed Venture Partners, Sequoia Capital, GIC, Coatue, J.P. Morgan, CapitalG, and Lead Edge Capital. Learn more at grafana.com and follow us on LinkedIn and X .

We’re scaling fast and staying true to what makes us different: an open-source legacy, a global collaborative culture, and a passion for meaningful work. Our team thrives in an innovation-driven environment where transparency, autonomy, and trust fuel everything we do.

You may not meet every requirement, and that’s okay. If this role excites you, we’d love you to raise your hand for what could be a truly career-defining opportunity.

This is a remote position. We are looking for candidates in the UK, Germany, Spain, Sweden and Ireland only.

The Opportunity

We build Pyroscope , the open-source continuous profiling database behind Grafana Cloud Profiles. Pyroscope gives engineers code-level visibility into how their applications use CPU and memory, down to the specific line of code, and connects that signal with metrics, logs, and traces across the Grafana stack.

2026 is an inflection point for Pyroscope. We completed the rollout of our V2 architecture, cutting production costs by 92% while significantly improving scalability, and grew the number of customers using the product by 64% last year. The product is moving beyond profiling-savvy users, and our focus is shifting from standalone feature development to reducing friction across the full experience: better onboarding, deeper integration with the rest of Grafana, and profiles that work for operational and SRE workflows, not just performance specialists.

Over the next year, you will help us:

• Ship Adaptive Profiles as the default ingestion strategy, so customers automatically collect the profiles they need at a cost that makes sense.

• Turn Pyroscope into a platform capability inside Grafana: bi-directional trace-to-profile correlation, integration with Kubernetes Monitoring and App Observability, and profiles surfaced where engineers already start their investigations.

• Prepare Pyroscope for an agent-driven world: APIs, CLI, and docs designed so AI agents can drive profiling end to end, covering the full performance optimization lifecycle from finding an issue to verifying the fix.

• Push operational excellence and TCO further: generalized autoscaling, better UX for long queries, and BYOC automation that brings up a new cell with zero manual intervention.

• Double adoption by making profiling easy to start with: guided onboarding, use-case-driven docs, and assisted instrumentation so users get value in minutes instead of days.

What You'll Be Doing

As a Senior Engineer on Pyroscope, you will own meaningful projects end to end and help shape what the team builds next.

• Lead projects from concept to rollout , e.g. Read path efficiency improvement, or trace-to-profile correlation, including design, delivery, operations, and customer follow-up.

• Design, build, and operate core components of a distributed database: ingestion, storage, and query, making sharp trade-offs on performance, cost, and complexity.

• Wear the product hat. We have no dedicated PM: engineers on this team join customer calls, translate pain points into manageable deliverables, and directly shape the roadmap. Your questions and ideas will steer what we build.

• Drive operational excellence. Own outcomes against concrete SLOs and unit cost targets, reduce toil through automation, and make on-call quieter every quarter.

• Partner across Grafana. Work closely with App Observability, Alloy, Tempo, and the other Databases squads to make profiles useful wherever engineers work.

• Support your teammates through design conversations, code review, and pairing in a fully remote setup.

• Participate in on-call (EMEA rotation) for the services you build, and treat incident response and post-incident learning as part of the craft.

• Contribute to open source. Pyroscope is OSS. You will engage the community, review external contributions, and help steer the project in the open.

We invest heavily in developer productivity. You can use modern AI coding assistants as part of your daily workflow (your choice of tools, within security guidelines), backed by a company-funded usage budget so you can iterate quickly without unnecessary friction.

We encourage pragmatic AI-assisted development: faster prototyping, test generation, refactors, documentation, and incident follow-ups, always paired with strong code review and quality standards. You'll also have access to frontier models (e.g., GPT-5.6, Claude Fable, Gemini Pro 3.1).

Example problems you could work on

These are the kinds of projects landing this year:

• Adaptive Profiles: sampling and aggregation strategies that keep the signal while cutting cost and noise, plus the ingestion metrics that make its behavior transparent to customers.

• Large queries: query fairness, async execution, and autoscaling of the read path so long queries from our largest tenants run efficiently at any scale.…
