Platform Solutions Architect

We impact the lives of over 40 million consumers daily by working with clients in the Baltics, the USA, Central and South America, and the Caribbean. We operate one of the largest big data environments in the Baltics, with one of the most diverse data sets, and we tackle some of the most challenging analytical and AI problems in the industry.

Exacaster’s team is looking for a Platform Solutions Architect to design the infrastructure foundations of our CVM product and our big data and Generative AI platforms for clients in telecommunications, finance, and investment management.

About the role

We are looking for an architect who turns business requirements into secure, reliable, and cost-effective platform infrastructure across cloud, on-premises, and hybrid environments. You will own the architecture for the networking, identity & access, storage, compute orchestration, observability, and security domains – the foundational capabilities that let our workloads run at scale and meet their SLAs.

This role is ideal for a hands-on infrastructure expert who enjoys working directly with clients, explaining trade-offs in business terms, and setting the standards that engineering teams build on. You will take architecture from discovery to production – designing the platform and deploying it yourself – run proofs-of-concept to de-risk new patterns, and mentor engineers and architects across the team.

In this role, you will take care of

• Architecture & roadmap: Own the infrastructure vision across cloud, on-prem, and hybrid environments, and lead complex migrations with minimal downtime.

• Client partnership: Run discovery with clients’ Security, Network, SRE, and FinOps teams and present trade-offs in business terms – risk, availability, cost, and complexity.

• Platform design: Design networking, identity & access, storage, and Kubernetes compute (incl. Airflow-orchestrated Spark workloads) – secure by default, with HA/DR and tested RTO/RPO targets.

• Security & compliance: Own decisions on encryption, audit logging, data residency, and retention in regulated industries.

• Automation & CI/CD: Build reusable IaC modules, GitOps pipelines (GitLab CI, ArgoCD), and self-service blueprints so teams can ship without waiting on the platform team.

• Cost optimization: Keep TCO under control through right-sizing, storage tiering, and reserved/spot strategies.

• Standards & mentoring: Set standards through design reviews, ADRs, and reference architectures, and coach engineers and architects across the team.
