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 Role

As a Block-Builder Engineer, you will take ownership of a production-grade, low-latency block-building platform and the systems around it.

You will work on the critical seal-and-submit path, block construction and bidding algorithms, parallel transaction simulation, secure builder-to-relay communication, and the off-chain logic supporting a new on-chain lending protocol and a trust-minimized TEE-based execution model.

A major part of the role is solving complex, open-ended engineering problems: improving bidding speed and efficiency, enabling capital to be safely borrowed and repaid within a single block, and creating mechanisms that prove correct system behavior without exposing competitive advantages.
 

Key Responsibilities

• Build and improve order-flow ingestion, bundle and transaction processing, relay submission flows, back-pressure mechanisms, and reintegration of channels into block construction.
• Develop and maintain observability tooling using Grafana, Prometheus, Loki, and SQL-based analytics, while identifying inaccurate or misleading metrics and dashboards.
• Design and execute production experiments, including A/B testing, data extraction, analysis, and clear reporting of results.
• Investigate and resolve production issues such as panics, dropped messages, latency regressions, and other reliability problems.
• Write tests and safeguards to prevent recurring failures and performance regressions.
• Contribute to optimization-driven block construction, protocol-level logic, and execution extensions such as BEX.
• Support the intrablock lending protocol by implementing both off-chain and on-chain components within the trusted-execution environment.
• Gradually expand into the exchange layer, building and maintaining high-throughput services that interact with trading systems.
   

Required Competence and Skills

• 2–4+ years of professional software engineering experience, including hands-on experience shipping and operating production systems.
• At least 2 years of experience working with Ethereum or other EVM-compatible blockchain protocols.
• Production experience with Rust is a strong advantage. Strong backend or systems engineering experience with Go, C++, or Java can also be considered if you are motivated and able to ramp up quickly in Rust.
• Experience working with concurrent, performance-sensitive, or real-time systems and confidence navigating a large existing codebase.
• Strong data skills, including SQL and experience using databases, logs, and production data to investigate system behavior and measure the impact of changes.
• Ability to use Python for analysis, automation, or internal tooling.
• Familiarity with monitoring and analytics tools, or a willingness to learn them, together with the ability to critically evaluate the accuracy of metrics and dashboards.
• A careful, data-driven engineering approach: validating assumptions, thoroughly testing changes, and distinguishing verified findings from hypotheses.
• Strong curiosity and ownership mindset, with an interest in understanding why production metrics change, identifying root causes, and iterating on solutions.
• Fluent English and willingness to work within Eureka Labs’ hybrid, office-first model in Poland.
   

Nice to Have

• Knowledge of or interest in Ethereum PBS, MEV, smart contracts, or trading systems.
• Experience with high-throughput data pipelines, time-series workloads, or large-scale analytics systems.
• Familiarity with reth, geth, or revm internals.
• Experience running production services with Kubernetes or Docker.

ABOUT OUR CLIENT

Our client is a leading enterprise data platform company building an open, high-performance data lakehouse for AI and analytical workloads. The platform combines an intelligent SQL query engine, an AI-ready semantic layer, and an open catalog built on Apache Iceberg — enabling Fortune 500 companies across finance, energy, manufacturing, and logistics to unify, query, and govern data at massive scale across cloud and on-premise sources.

ABOUT THE ROLE

We are looking for a Senior Software Engineer for the connectivity stack of a large-scale data platform. The work spans three areas:

• Client connectivity — drivers and client libraries used by applications and BI tools
• Source connectivity — connectors to databases and data systems, including authentication, metadata discovery, and query/data pushdown, with certification and upgrade support
• Agent & service connectivity — tool interfaces and integrations for AI-agent access to the platform

Deep expertise in one of these areas is enough — you'll grow into the adjacent ones over time. This is a role for an engineer who cares about API and protocol stability, backward compatibility, and interoperability with the tools enterprises actually use. You will lead the design and delivery of substantial components, working within an established architecture alongside US-based engineering reviewers.

This is a systems-level, backend engineering role focused on drivers, protocols, and distributed services — not application development or CRUD services.

RESPONSIBILITIES

• Lead the design and delivery of connectivity components — client drivers, source connectors, and service integrations — turning ambiguous initiatives into well-scoped, reviewable milestones
• Produce technical designs, explain architectural trade-offs, and surface compatibility, security, and delivery risks early
• Maintain backward compatibility and API/protocol stability; build compatibility, interoperability, and performance test suites
• Develop and maintain connectors for major BI tools, collaborating with the technology partners behind them
• Diagnose complex client/server, protocol, and distributed-system failures; drive root-cause analysis of customer-reported and escaped defects
• Improve diagnostics, logging, observability, and supportability of the connectivity stack
• Contribute upstream to open-source projects (e.g., Apache Arrow) where agreed
• Mentor engineers, participate in code and design reviews, and communicate progress and risks clearly across a distributed team

REQUIRED QUALIFICATIONS

• B.S. or M.S. in Computer Science, Computer Engineering, or a related field — or equivalent practical experience
• 8+ years of production software engineering experience
• Deep proficiency in Java or C++, and the ability to work effectively in another systems/services language
• Experience designing and debugging APIs, protocols, client libraries, or distributed services
• Strong fundamentals: data structures, concurrency, asynchronous programming, networking, and failure handling
• A track record of comprehensive testing — unit, integration, compatibility, and performance
• Experience with production CI/CD, release processes, and engineering quality controls
• Working knowledge of SQL
• Comfortable with AI-assisted development workflows — using modern AI tools productively while critically validating their output
• Clear written and verbal communication in a distributed engineering environment; English Upper-Intermediate or higher (B2+)
• Availability to work EU business hours shifted 2–3 hours later for daily overlap with US West Coast mornings

DESIRED SKILLS

• JDBC, ODBC, ADBC, or database-driver development experience
• Apache Arrow (including Arrow Flight)
• SQL engines, databases, or data platforms
• Source-connector development for databases, warehouses, or SaaS systems
• MCP or agent-tool integrations
• OAuth, OIDC, TLS, and enterprise authentication flows
• Cross-platform native build, packaging, and release experience
• BI-tool interoperability (Power BI, Tableau) and partner collaboration
• Observability and production diagnostics
• Open-source contribution experience

DETAILS

• Engagement: Long-term contract
• Location: Europe (EU / EEA / UK), remote
• Working hours: EU business hours, shifted 2–3 hours later for daily overlap with the US West Coast team
