Middle DevOps Engineer

Job description

We're looking for a DevOps Engineer to join our team and work embedded with one of our key clients — a fast-growing AdTech SaaS company operating at scale on AWS. You'll be part of a small, high-ownership DevOps team working closely with the client's backend, data, and product engineers on a daily basis.

This is a hands-on role. You'll handle everything from routine infrastructure maintenance to complex migrations, security hardening, and cost optimization — and you'll be expected to communicate clearly with both technical and non-technical stakeholders.

What you'll work on:

- Managing and evolving cloud infrastructure on AWS (EKS, RDS, ElastiCache, S3, OpenSearch, Cognito, SES, and more)

- Maintaining and improving CI/CD pipelines built on GitHub Actions and ArgoCD

- Writing and maintaining infrastructure-as-code with Terraform (including Terraform Cloud)

- Supporting Kubernetes clusters (EKS) with Karpenter autoscaling and Bottlerocket OS

- Participating in security initiatives — MFA enforcement, WAF configuration, GitHub branch protection, GPG commit signing, ISO 27001 compliance

- Monitoring and alerting via Datadog and responding to incidents

- Managing AWS Bedrock integrations and supporting AI-powered services

- Supporting developer teams with access management, environment provisioning, and day-to-day requests

Contributing to cost optimization efforts and monthly AWS cost reporting

What we're looking for

Required:

- Experience with ArgoCD or other GitOps tools

- Solid understanding of AWS core services (EC2, S3, RDS, IAM, VPC, EKS)

- Hands-on experience with Terraform

- Familiarity with Kubernetes and Helm

- Experience with CI/CD pipelines (GitHub Actions or similar)

- Comfortable working in Linux environments and with CLI tooling

- Strong written communication in English — you'll be interacting with client stakeholders daily

- Ability to work independently, ask the right questions, and take ownership

Nice to have:

- Familiarity with Datadog or similar observability platforms

- Knowledge of AWS security services (WAF, GuardDuty, Security Hub)

- Experience with ElastiCache, OpenSearch, or Databricks

- Exposure to ISO 27001 or SOC 2 compliance processes

- Familiarity with AWS Bedrock or AI/ML infrastructure

What to expect

- You'll be embedded in a real product team, not bouncing between projects every few weeks

- Small team, high ownership — your work matters and is visible

- Direct communication with client engineers and stakeholders

- Fully remote, async-friendly, with regular syncs

- You'll be expected to grow into the role — we invest in people who take initiative

What we offer:

- Paid vacation — 16 days per year;

- Documented (16 days) and undocumented (5 days) sick leave;

- Leave for significant life events;

- Compensation for medical insurance (for our employees based in UA);

- Flexible working hours (start at 8.00-11.00 o’clock);

- Weekends according to the Ukrainian/Local calendar;

- Engaging projects with opportunities for career growth;

- Certifications, Udemy courses;

- Corporate events, team-building activities,

- Gifts and recognition from the company;

- A friendly, open, and supportive team culture without excessive bureaucracy.
