Senior Backend Engineer - Databases Tempo

Grafana Labs is the company behind Grafana Cloud, a fully managed observability platform trusted by over 10,000 organizations. Built on open source and open standards, Grafana Cloud brings AI to observability, providing unified visibility across disparate data. We are a 100% remote company with team members across 40+ countries.

We are scaling fast, maintaining our open-source legacy, global collaborative culture, and passion for meaningful work. Our team thrives in an innovation-driven environment where transparency, autonomy, and trust are paramount.

This is a remote position, and we are seeking candidates in the US and Canada.

The Opportunity

We build Tempo, the open-source distributed tracing backend powering Grafana Cloud Traces and Grafana Enterprise Traces (GET). Tempo simplifies trace searching, metric generation from spans, and connects tracing data with logs, metrics, and profiles across the Grafana stack.

2026 marks an inflection point for Tempo. Following a major architectural upgrade and the launch of TraceQL metrics, we are transitioning from foundational work to product and operational excellence. Tempo is evolving from a SaaS database into a platform that will power Grafana’s next generation of observability products (App Observability, Asserts, Traces Drilldown, and AI-driven assistants).

Over the next year, you will help us:

• Make Grafana Cloud Traces “just work” for customers by eliminating rough edges, confusing limits, and hidden failure modes.
• Achieve operational excellence at scale, growing from nearly 50 cells today into triple digits this year, with autoscaling, parameterized rollouts, and aggressive toil reduction.
• Evolve Tempo into a platform enabler: higher-density APIs, trace aggregation, TraceQL metrics math, and machine/LLM-friendly interfaces for downstream products and agents.
• Push performance further: faster query latency at hundreds of MB/s ingestion and performant 30-day query ranges to match competitors.
• Prepare Tempo for an agent-driven world: larger, burstier, higher-cardinality workloads, and new categories of AI-powered workflows, such as assistant-driven triage and “why is this slow?”-style investigations.

What You’ll Be Doing

As a Senior Engineer on Tempo, you will own the technical direction for the hardest problems on our roadmap and raise the bar across the team.

• Deliver significant technical projects. Take well-scoped, multi-month initiatives from problem framing through rollout, such as trace aggregation APIs, Limitless Tempo, autoscaling cells and customer limits, or query engine improvements. Partner with Staff engineers and the tech lead on broader, cross-team direction.
• Own major components of Tempo. Contribute to and own parts of ingestion, storage, query, and metrics generation. Write and present design docs, participate in design reviews, make sound trade-offs on performance, cost, and complexity, and document the “why” for the team.
• Build APIs for humans and agents. Help shape the next generation of Tempo’s interfaces (structured, deterministic, discoverable) so that Act 3 products, LLM-driven assistants, and external integrators can build on Tempo reliably.
• Contribute to operational excellence. Own outcomes for the areas you build against concrete SLOs (P99 write latency, incident recurrence, TCO per ingested GB), and help move the team toward Zero Ops through automation, parameterized rollouts, and actionable alerts.
• Collaborate with Product and sibling teams. Work with Product Managers and with App Observability, Asserts, Drilldown, and Grafana Assistant teams to understand how Tempo is consumed and to ship what unblocks them.
• Mentor and support engineers. Raise the bar through thorough code review, constructive design feedback, and pairing, especially with junior and mid-level engineers.
• Participate in on-call for the services you help build, and contribute to incident response and post-incident learning.
• Contribute to open source. Tempo is OSS. You will engage the community, review external contributions, and contribute to 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. We encourage pragmatic AI-assisted development: faster prototyping, test generation, refactors, documentation, and incident follow-ups—always with strong code review and quality standards. You'll also have access to the latest frontier models from OpenAI, Anthropic, and Google.

Example Problems You Could Work On

These are the kinds of projects landing in 2026:

• Trace aggregation and higher-density APIs: extend TraceQL metrics, design LLM-friendly response types, and make Tempo a first-class data source for Grafana’s AI assistant.
• Autoscaling end-to-end: customer limits and Tempo cells, with hysteresis, predictive scaling for spikes, and safe scale-down.
• Agent-scale ingestion and query: guardrails for bursty, high-cardinality, agent-generated workloads.
• Query performance: new data formats, smarter query pipelines, targeted optimizations for common Drilldown and Traces workflows, and 30-day query ranges.
• Rollouts and multi-cell operations: parameterized rollouts, push-button deploys, and the tooling to grow safely into triple-digit cell counts without a proportional increase in alert noise.
• Limits and self-service: drive customer-facing configuration and observability so escalations trend toward zero.

What Makes You a Great Fit

• Technical ownership. A track record of delivering complex, multi-month projects that spanned design, delivery, and operations, and of helping teammates grow.
• Solid systems experience. Significant hands-on experience building and operating distributed data systems in production: ingestion pipelines, storage engines, query execution, or similar.
• Strong software craftsmanship. You write clean, robust, performant software that others can maintain, and you know when to optimize vs. when to ship.
• Strong Go, or a path to it. We write Tempo in Go. Solid experience in other systems languages (Rust, C, C++) translates well.
• Operational mindset. You’ve owned production services, carried a pager, reduced toil, and treated SLOs as a product feature, not a chore.
• Customer focus and pragmatism. You break complex problems into short feedback loops: analyze, design, deliver an MVP, learn, iterate.
• Collaboration and clear writing. You contribute through design docs, reviews, and shipped code, and you communicate clearly in a fully remote, asynchronous environment.

Bonus Points For

• Experience with tracing, OpenTelemetry, or large-scale observability systems.
• Experience designing query languages, SQL/TraceQL-like engines, or APIs intended to be consumed programmatically (by services or agents).
• Experience with columnar storage formats (e.g., Parquet) or purpose-built on-disk formats for analytical workloads.
• Experience operating multi-tenant, multi-cell SaaS infrastructure at scale on Kubernetes.
• Experience building for AI/LLM consumers: structured APIs, metadata/discovery endpoints, deterministic outputs, evaluation harnesses.
• Open-source contribution or maintainership, and comfort engaging a community in the open.
• Experience as an on-call user of Grafana, Prometheus, Loki, or Tempo in a previous role (or on a homelab).
• Experience in a fully remote, globally distributed team.
