Technical Lead, Observability - London

H Company; Paris; Hybrid; EUR 110,000 - 150,000; Full time

Job summary

H Company seeks a senior observability lead to own strategy, design, and rollout across all products. You will create a unified view of metrics, logs, traces, and dashboards, surfacing information essential to decision making and product reliability.

You will stay hands-on, define SLAs/SLOs/SLIs with cross‑functional teams, implement end‑to‑end visibility, and drive adoption of instrumentation and standard SDKs across our stack, with a strong focus on scalable, self‑managed observability.

Qualifications

• Led the direction for a substantial engineering observability effort.
• Built production instrumentation and telemetry integrations.
• Defined product- and technical-level SLAs, SLOs and SLIs.
• Applied SRE measurements such as error budgets and MTTR.
• Implemented self-managed observability stacks (OTEL, Prometheus, Grafana).
• Collaborated with Kubernetes at scale and multi-tenant environments.

Responsibilities

• Set one observability strategy across teams and stacks.
• Own the implementation of metrics, logs, traces, alerts, and dashboards.
• Define and ensure compliance with SLAs, SLOs, and SLIs.
• Provide end-to-end visibility of system dependencies with visualisations.
• Automate coverage tracking, reliability metrics, and cost of execution.

Job description

You'll own observability across H: the strategy, technical design and rollout. Your work will give visibility of the entire stack and surface the information the company relies on to make key decisions and quantify progress.

H builds computer-use agents that take actions in browsers and desktop applications. This role covers every technical system we run.

What you own

The whole problem space. This is a lead role that stays hands-on: you will set the direction, design the stack, lead others through building it and work with internal teams on adoption. You'll be responsible for ensuring our teams measure what matters, and for learning our products and services in depth.

What you'd be doing

• Setting one observability strategy that can be applied across teams and technical stacks

• Owning the implementation of the systems that manage metrics, logs, traces, alerts and dashboards

• Defining SLAs, SLOs and SLIs with our product, research and infrastructure teams

• Building end-to-end visibility of system dependencies, providing visualisations for users and context for agents

• Automating how we track coverage, reliability, alert quality and the cost of execution

The first year

By month 3, every H product has SLAs, SLOs and SLIs defined and measured in code, with compliance reports produced automatically. By month 6, a single complete solution covers metric collection, log processing and tracing. By month 12, every system at H uses the same SDKs and interfaces, whether for alarms, metrics, logs or traces.

Who you'd work with

You'll work with every team at H, across infrastructure, product, engineering and research. Our VP of Engineering is the hiring manager.

What we think it takes

Likely a good fit if you

• Have set the direction for a substantial piece of engineering work, delivered it and got other teams to adopt it.

• Have built production instrumentation and telemetry integrations yourself.

• Have defined both product-level and technical-level SLAs, SLOs and SLIs.

• Have used SRE measurements such as error budgets, burn rates and MTTA/MTTR/MTTM.

• Have built self-managed observability systems, such as OTEL, Prometheus, Grafana, Loki, Mimir, Alloy, Elasticsearch or Kibana.

• Have worked with Kubernetes at scale, enterprise multi-tenancy, inference or asynchronous agent workflows.

You do not need any experience in AI. If you match most of this but not every point, don't hesitate to apply.

Practicalities

The role is hybrid, with three days a week in either our Paris or our London office and occasional travel between the two. We offer a competitive package.
