About the role We are looking for a Test Automation Engineer to join our

Observability & Monitoring software development team. The team builds and operates internal, custom monitoring and observability platforms that provide deep visibility into our services, enabling proactive detection, faster incident resolution, and improved reliability across the company.

As an Automation Engineer, you will take an engineering-first approach to quality , designing and building automated testing solutions, frameworks, and tooling to ensure the reliability of systems handling large volumes of metrics, logs, alerts, dashboards, and data pipelines .

A key challenge in this role is working with high‑volume telemetry data , where quality is not only about correctness but also about signal accuracy

— reducing false positives, detecting missing data, and ensuring that the system reflects reality as closely as possible.

Define team's testing strategy

Design and implement automated test frameworks and tooling for backend systems and APIs





Develop end-to-end and integration test suites for observability platforms

Validate the correctness, consistency, and completeness of metrics, logs, and alerting systems

Analyze system behavior to detect false positives, false negatives, and data inconsistencies

Test dashboards and visualizations built with

Grafana and Kibana

Test data flows across time-series and relational databases

Integrate test suites into

CI/CD pipelines and enforce automated quality gates

Work closely with developers to improve system testability and reliability

Identify coverage gaps and build scalable automation solutions

Participate in incident analysis and design tests to prevent regressions

Ensure changes are covered by appropriate regression tests to maintain system stability

Our tech stack (what you’ll work with)

Python

(services and test automation)

Elastic stack

(logs, events, search)

Kibana dashboards and visualizations

Grafana dashboards and alerting

InfluxDB

(time-series data)

PostgreSQL

(relational data)

Kubernetes

(container orchestration)

AWS services

(cloud infrastructure)

APIs and backend services supporting a custom, in‑house monitoring platform

CI/CD pipelines with automated testing and quality gates

Solid programming skills in

Python

Experience building and maintaining test frameworks and automation tooling

Experience testing

APIs, backend systems, and distributed services

Strong ability to work with data-intensive systems

(metrics, logs, events)





Ability to analyze system behavior and detect anomalies, inconsistencies, and signal quality issues

Understanding of

CI/CD pipelines and automated quality gates

Strong analytical and problem-solving skills

Nice to have

Experience with observability or monitoring platforms

Familiarity with

Elastic, Kibana, Grafana, InfluxDB, PostgreSQL

Exposure to

Kubernetes and cloud environments (AWS)

Experience testing distributed systems

Knowledge of performance, reliability, or resilience testing

Experience in Agile / Scrum teams

How we work

Quality is an engineering responsibility , not a final checkpoint

Testing is code-driven, automated, and scalable

Strong focus on data correctness, signal quality, and system reliability

We continuously balance precision vs noise in monitoring systems

We value pragmatism, ownership, and continuous improvement

We work in a hybrid remote model , balancing flexibility with collaboration

Work on core internal platforms with high impact on reliability and operations

Challenges involving large-scale telemetry, signal accuracy, and system behavior

Strong engineering culture with collaboration across testing, development, and DevOps

Modern,

cloud-native and automation-first environment

Hybrid remote working model

Competitive compensation and local benefits

International, collaborative engineering environment

Beyond the Job We’re proud of our focus on Environment, Social and Governance as well as the passion we display for the communities where we live and work.
