DevOps / Site Reliability Engineer

Joom Group is an international tech-centric group of e-commerce companies founded in 2016 in Latvia. We are here to transform the largest industry in the world, global trade, making it more transparent, efficient, and technology-driven. 

Today, Joom Group brings together the following businesses: Joom, a platform for shopping from all over the world; JoomPro, the first end-to-end cross-border B2B marketplace, with successful operations in Brazil and plans to expand to other markets; JoomPulse, data platform that provides analytics and recommendations for marketplace sellers; and Onfy, a pharmaceutical marketplace in Germany. Joom Group’s offices are located in China, Brazil, Portugal, Latvia, and Germany, with headquarters in Lisbon, Portugal. We work as one international team, sharing knowledge and collaborating across countries, businesses, and products. 

We are looking for an experienced engineer to join our Infrastructure team. The team is responsible for the support and development of the company's key infrastructure components. We run and evolve a fleet of ~20 Kubernetes clusters, where the vast majority of our infrastructure resides.

This role is about impact: the architectural decisions you make and the tools you implement will directly influence the stability and workflow of multiple product teams and business units.

Our Approach

• High efficiency: We are a team of 8 engineers managing a huge infrastructure platform. We achieve this through automation and self-service, not manual toil
• Reliability: We take stability seriously. We can easily add an "8" to our SLO targets. We want you to help us add a "9"
• Code-first: We strictly follow IaC/CasC approaches to maintain consistency and scalability as well as write missing automation in Go or Python
• Engineering culture: We maintain a high bar for code quality, yet we dislike bureaucracy. We trust your engineering judgment to balance safety with speed when the situation requires it
• Sleep-friendly duty: Our duty rotation acts primarily as an incoming interface during business hours. Night calls are exceptional events (around once in a few months). We value our sleep and aim to keep it that way
• AI-curious: We actively explore AI tools to automate routine tasks, speed up troubleshooting and navigate across large codebases. AI assists with drafts and context gathering; engineers review and own every change

Technological Stack

• Cloud: GCP (primary), AWS
• Core: Kubernetes (foundation of our fleet), Linux (Ubuntu)
• IaC / CasC: Terraform, Terragrunt, Ansible
• Programming languages: Go, Python
• Observability: Prometheus, Victoria Metrics, Grafana
• Other services: Keycloak (OIDC/SSO), FreeIPA, HashiCorp Vault, JFrog Artifactory

Requirements

• Production experience: solid background in DevOps/Infrastructure roles at scale
• Linux proficiency: solid understanding of Linux system internals
• Kubernetes expertise: deep understanding of operating Kubernetes at scale
• Coding: ability to write automation and tooling in Go or Python
• Cloud Knowledge: experience with GCP, AWS or other cloud platforms
• Observability: experience with modern monitoring stacks (Prometheus, Victoria Metrics)

Preferred

• Experience with networking fundamentals (BGP, IPsec) – rarely needed, but good to know
• Experience with GitOps (ArgoCD, Flux)
• Experience with FinOps

We offer

• Compensation package: base salary and performance-based bonuses
• Office-first: flexible hours with a possibility to work remotely 52 days per year
• Care & Wellbeing: health insurance (including dental care) for employees and their children, daily meal allowance, and 100% paid sick leave
• Relocation Support: full assistance for a smooth relocation for the employees and their family
• Team & Growth: collaboration with colleagues across Portugal, Brazil, Latvia and China, with opportunities for promotions, professional trainings, and English & Portuguese courses
• Community & Engagement: annual team building activities, knowledge-sharing workshops, and a strong sense of team work
