Job Title:

Principal DevOps Engineer

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:

Our client is a major online gaming operator building a next-generation transactional platform for user account management. This is a greenfield project designed to operate in a highly regulated, high-volume environment and support millions of concurrent users. The platform will process financial transactions in real time and must ensure high availability, sub-second performance, data integrity, security, and full auditability. One of the key engineering challenges is maintaining reliability and performance during extreme traffic spikes and peak events. 

The team is looking for strong technical expertise to help design and build a scalable, secure, and reliable platform that can meet strict regulatory and compliance requirements.ip and expertise are critical to ensure reliability, performance, and compliance at scale.

About the Role:

As a Principal DevOps Engineer, you will take the lead in building the cloud infrastructure and delivery platform from the ground up. You will shape the multi-account cloud foundation, network architecture, security controls, Kubernetes strategy, CI/CD pipelines, and observability framework before production workloads go live. The role combines hands-on infrastructure-as-code development with platform strategy, incident readiness, and compliance by design. You will work closely with engineering, security, and AI platform teams, share operational best practices, and ensure the platform remains highly available, secure, and performant at scale.

Key Responsibilities:

• Design and implement a multi-account cloud foundation: account structure, landing zones, VPCs, Transit Gateway, IAM policies, and cost governance.
• Build and operate a resilient container platform using Amazon EKS, service mesh configuration, autoscaling strategies, and multi-AZ or multi-region deployment.
• Develop and maintain infrastructure as code using Terraform or equivalent, and enable GitOps delivery with tools such as Argo CD.
• Create paved-road CI/CD pipelines to automate application build, test, and deployment processes for multiple product teams.
• Establish an observability stack including metrics, logs, tracing, and alerting (Prometheus, Grafana, OpenTelemetry, CloudWatch) and drive an SLO/error budget practice.
• Define and own production readiness: incident response process, on-call rotation design, runbooks, and chaos/load testing for major events.
• Lead migration of existing third-party platform components: dual-running environments, data migration pipelines, and cutover planning.
• Embed compliance into infrastructure: audit trail automation, environment segregation, backup/DR strategy, and controls aligned with regulatory requirements.
• Partner with AI platform engineers to provision and operate AI-assisted development infrastructure and integrate AI tools into DevOps workflows.
• Mentor and guide engineers organization-wide on cloud-native architectures, operational excellence, and infrastructure best practices.

Required Competence and Skills:

• 10+ years of experience in DevOps, Platform, or Infrastructure Engineering, including 3+ years at Staff/Principal level with organization-wide impact.
• Deep hands-on AWS expertise: EKS, EC2, RDS/Aurora, VPC, Transit Gateway, Route 53, IAM, and multi-account environments.
• Strong Terraform and Kubernetes expertise, including day-2 operations, upgrades, capacity planning, and cost optimization.
• Proven experience building CI/CD pipelines and developer platforms used across engineering teams.
• Experience running high-availability, high-throughput systems and handling major traffic spikes.
• Strong scripting/programming skills in Python, Go, or Bash, with the ability to review application code for infrastructure integration.
• Experience with backup, disaster recovery, and business continuity for critical systems.
• Excellent English communication skills, with the ability to explain technical decisions to both engineers and executives.

Nice to Have:

• Experience with cloud security, secrets management (e.g., Vault), and CI/CD security scanning (SAST/DAST/SCA).
• Familiarity with ISO 27001, SOC 2, or PCI DSS standards.
• Experience in online gaming, sports betting, fintech, or other regulated, high-transaction industries.
• Experience migrating from third-party vendor platforms.
• Knowledge of event streaming (Kafka/MSK) and large-scale database operations.
• Polish and/or Spanish language skills.
•  

Why Us:

We provide 20 days of vacation leave per calendar year (plus official national holidays of a country you are based in).

We provide full accounting and legal support in all countries we operate.

We utilize a fully remote work model with a powerful workstation and co-working space in case you need it.

What we are building
A data product that maps gambling regulation across more than 200 jurisdictions: which markets are open, who licenses operators, how they are taxed, what the advertising and player-protection rules are, and how all of it changes. Today it is a public, content-heavy site with strong organic traffic. Behind it sits a research database, a CMS for editors, and a monitoring system that reads regulators, gazettes and parliaments every day and turns what it finds into alerts and, increasingly, into corrections on the pages themselves.
Two things are changing. The front end is getting a full redesign with a product designer who has just joined. And the product is moving from a public reference to a paid one: user accounts, reports people can buy and find in their account, and a back office to run it. None of that exists yet. You would build it.

What you would own
 

• The web application. Next.js and TypeScript. Implement the redesign with the designer, keep the site fast and indexable, and later add accounts, authentication, payments and purchasable reports.
• The data layer. Several SQLite stores with a strict one-way flow from canonical data to mirrors, validation gates that refuse silent data loss, and scripts that apply researched corrections. You would keep these aligned and extend them as the product grows.
• The monitoring pipeline. Python services on a Linux server: crawlers for regulator sites, gazettes and parliaments, a matching layer, model-based vetting, and a Telegram bot the team uses to approve findings. You would make it catch more, post less noise, and land approved changes on the site.
• AI in the loop. We use models to build and to vet. You would design the pipelines that call them with fixed schemas, verify their output against the source, and treat everything they return as a claim until checked.
• Operations. One server, systemd, our own deploy script with rollback, continuous database replication, Cloudflare in front. Deploys must not break the live site, and the person who owns the code owns that too.
• The back office. Once accounts and reports exist, the tooling for the team to manage customers, content and data without touching the database by hand.
   

What we need from you
 

• Senior experience shipping and running production web applications end to end.
• Strong TypeScript and React. Next.js specifically, or the willingness to be fluent in it within weeks.
• Comfortable in Python for scripts, crawlers and services. Most of the monitoring code is Python and you will inherit it.
• Solid SQL and a habit of validating data rather than trusting it. Experience with SQLite is a plus; the discipline matters more than the engine.
• Linux server operations: systemd, deploys, backups, reading logs before guessing.
• Experience integrating LLMs into a pipeline with structured outputs, and a clear view of why model output is data, not instruction.
• A verification mindset. This product is only worth anything if the facts on it are right. You read the primary source, you check the figure, you say when you are not sure.
• Clear written communication. Most of our coordination is asynchronous and in writing.
   

Nice to have
 

• Technical SEO experience. The site lives on organic search.
• Auth, payments and subscription systems built from scratch.
• Scraping hostile or JavaScript-heavy sites, and knowing when to stop and look for an API instead.
• Interest in regulation, compliance or legal data. You do not need to know gambling law; you need to care whether a statute citation is real.
   

How we work

Small team, direct communication, decisions written down with the reason attached. Nothing in the current architecture is sacred: it reflects choices made along the way, and if you see a better direction for the code, the data layer or how we run things, we want that conversation. AI writes a lot of our code; your judgement decides what ships.
