Who we are:

Adaptiq is a technology hub specializing in building, scaling, and supporting R&D teams for high-end, fast-growing product companies in a wide range of industries.

About the Product:

Vetric provides a public data intelligence API that ingests and structures high-volume web and continuous video feeds from major social networks, including LinkedIn, Facebook, Instagram, TikTok, Twitter and YouTube, to surface real-time signals for cybersecurity, public safety and digital risk protection platforms. Its infrastructure processes tens of millions of data requests daily and supports analytics on large-scale stores such as ClickHouse, ScyllaDB, DynamoDB, RDS and Redis. By enabling detection of bad actors, impersonations, fake news, extremists and brand abuse, Vetric solves critical visibility gaps across security and compliance workflows. The scale and data intensity of its mission-critical pipelines demand production-grade reliability, deep engineering rigor and long-term operational excellence to deliver consistent, actionable intelligence.

About the Role:

You will join Vetric’s infrastructure team in the Krakow engineering hub as a Senior DevOps Engineer, reporting to the DevOps Team Leader. In this role you will own the end-to-end delivery of advanced cloud infrastructure, from designing and coding new platform components through production hardening and operational support. You will work closely with teams in Poland and Israel, exercise high autonomy, and make strategic technical trade-offs that influence the reliability, security and cost-efficiency of Vetric’s global data pipelines. Your contributions—migrating container workloads, evolving IaC frameworks, scaling data-intensive systems and enforcing observability standards—will directly shape the performance and resilience of the product at scale.

Key Responsibilities:

• Architect and execute zero-downtime migration of container workloads from AWS ECS Fargate to Kubernetes (EKS).
• Design, develop and maintain modular Infrastructure as Code across multiple environments using Terraform and OpenTofu.
• Evolve enterprise CI/CD pipelines with GitHub Actions, OIDC federation and safe rollout strategies to improve deployment safety and developer velocity.
• Monitor and tune performance, capacity and resilience of high-volume data infrastructure including ClickHouse, ScyllaDB, DynamoDB, RDS and Redis.
• Implement and enforce reliability and observability standards using telemetry tools such as OpenTelemetry, Coralogix and Grafana.
• Make data-driven trade-offs balancing speed, security (least-privilege, zero-trust) and cost efficiency (FinOps).
• Collaborate across distributed teams to build secure, compliant and scalable cloud infrastructure aligned with organizational requirements.
• Own on-call rotations, incident management and operational response processes driven by signal over noise.

Required Competence and Skills:

• 5+ years of hands-on experience in DevOps, Infrastructure or Cloud Engineering in data-intensive, high-throughput environments.
• Advanced AWS expertise across compute, networking (VPC, DNS, segmentation), IAM and scalability patterns.
• Production-scale Kubernetes mastery (EKS), including cluster architecture, optimization and heavy-load operations.
• Expertise in Terraform or equivalent IaC tools plus scripting or software engineering in Python, Go or TypeScript; strong Bash skills.
• Deep understanding of container orchestration (Docker, ECS) and modern CI/CD practices with safe rollout mechanisms.
• Proven track record building observability and alerting stacks (metrics, logs, traces, SLOs) at scale.
• Strong communication skills, pragmatic leadership and ability to work autonomously in high-velocity teams.

Nice to Have:

• Direct experience migrating production workloads from ECS to Kubernetes.
• Familiarity with EKS ecosystem tools (Karpenter, ArgoCD/Flux, KEDA, VPC CNI).
• Experience operating wide-column or analytical databases at scale such as ClickHouse or ScyllaDB.
