About the Product:

We build foundational public data infrastructure that powers mission-critical platforms in cybersecurity, public safety and digital risk protection. Our systems ingest and structure high-volume web data and continuous video feeds from major social networks via a stable API, delivering reliable signals that integrate into core customer products. We operate a multi-account AWS environment handling tens of millions of data requests daily and support analytics on high-scale data stores such as ClickHouse, ScyllaDB, DynamoDB, RDS and Redis. Engineering discipline, long-term thinking and operational excellence underpin our work—every data flow is production-grade and designed for scale, reliability and depth.

About the Role:

We are seeking a Senior DevOps Engineer to join our infrastructure team in a European engineering hub. Reporting to the DevOps Team Leader, you will own end-to-end delivery of advanced infrastructure initiatives—from design and implementation through production hardening. You will tackle real-world challenges including migrating container workloads from ECS Fargate to Kubernetes without downtime, evolving Infrastructure as Code frameworks, scaling data-intensive pipelines, and enforcing robust observability and reliability standards. This role offers high autonomy, direct impact on global products, and the opportunity to set the technical bar for operational excellence.

Key Responsibilities:

• Architect and execute migration of container workloads from ECS Fargate to Kubernetes (EKS) with zero downtime.
• Design and maintain modular Infrastructure as Code using Terraform and OpenTofu across multiple environments.
• Evolve enterprise CI/CD pipelines with GitHub Actions and OIDC federation to improve developer velocity and deployment safety.
• Oversee performance, capacity and resilience of high-volume data infrastructure (ClickHouse, ScyllaDB, DynamoDB, RDS, Redis) and event-driven messaging.
• Implement and enforce reliability and observability standards using telemetry tools (OpenTelemetry, Coralogix, Grafana).
• Make data-driven tradeoffs balancing speed, security (least-privilege, zero-trust access) and cost efficiency (FinOps).
• Collaborate across distributed teams to deliver secure, compliant and scalable cloud infrastructure.
• Own operational responses, on-call rotations and incident management driven by signal, not 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 design, optimization and heavy load management.
• Expertise in Terraform (or equivalent) and scripting/software engineering in Python, Go or TypeScript; strong Bash skills.
• Deep understanding of container orchestration (Docker, ECS) and modern CI/CD with safe rollout strategies.
• 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 (ClickHouse, ScyllaDB).

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.

Job Title:

Block-Builder 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:

An advanced block construction platform operating on the Ethereum mainnet that processes order flow, transaction bundles, and submits finalized blocks through relay networks in real time. It addresses neutral and efficient block building to unlock new decentralized finance capabilities, including intrablock lending and execution extensions. The system handles high-throughput data pipelines and strict latency requirements, backed by comprehensive observability and analytics to drive iterative improvements based on live production metrics. Strong engineers are essential to maintain system health under real-time load, verify data-driven hypotheses, and innovate on core protocol logic.

About the Role:

The Block-Builder Engineer will join an experienced team in Kraków or Warsaw to develop and maintain a next-generation Ethereum block construction system. You will own pipeline components that ingest order flow and transaction bundles, manage relay submission paths, and ensure stable performance under real-time load. Your work will include building and refining observability platforms, conducting controlled A/B experiments, and driving reliability improvements such as panic mitigation and latency regression detection. As you ramp, you will contribute to optimization-driven block building logic, on-chain intrablock lending protocols, and an execution extension, gaining autonomy and deep technical ownership across the core stack.

Key Responsibilities:

- Integrate and process order-flow ingestion, bundle and transaction handling, back-pressure management, and reintegration of data for block inputs.

- Develop and maintain relay submission paths to ensure end-to-end block delivery under production load.

- Build and enhance telemetry and dashboards using Grafana, Prometheus, Loki and SQL to provide trusted observability.

- Diagnose and correct measurement issues—broken counters, misleading dashboards, and erroneous denominators—to maintain metric accuracy.

- Design, execute and analyze controlled A/B experiments in production, reporting findings objectively, including inconclusive results.

- Identify and resolve system panics, dropped messages, and latency regressions, with automated tests to prevent recurrence.

- Optimize data pipelines and processing systems for high-throughput, low-latency performance.

- Contribute to the development of intrablock lending protocols and associated trusted-execution components.

- Collaborate on an execution extension (BEX) and future protocol and exchange-layer enhancements.

Required Competence and Skills:

- 2–4 years of professional software engineering experience shipping and operating production systems.

- Minimum 2 years working on Ethereum or other EVM-compatible blockchains.

- Proficiency in Rust or strong systems experience in Go, C++ or Java with eagerness to adopt Rust.

- Solid understanding of concurrent and real-time code within large, existing codebases.

- Strong SQL skills and practical experience with Python for data analysis and tooling.

- Familiarity with monitoring and analytics tooling and a drive to ensure metric correctness.

- Rigorous engineering habits, including comprehensive testing and clear distinction between verified and assumed behavior.

- Data-driven mindset with a habit of querying logs and databases to validate change impact.

Nice to Have:

- Exposure to Ethereum block-building protocols (PBS/MEV), smart contract interactions, or trading systems.

- Experience with high-throughput data pipelines, time-series databases, or large-scale analytics.

- Familiarity with Ethereum client internals (reth, geth, revm) or deploying services on Kubernetes and Docker.

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.

We offer a highly competitive package with yearly performance and compensation reviews.
