About Flamingo

Flamingo is revolutionizing the Managed Service Provider (MSP) industry with an AI-driven, open-source platform for IT and security. Our goal is to empower MSPs with automation, optimization, and scalability tools to enhance their operations.

We are now expanding our system layer, developing cross-platform agents and background services written in Rust, designed to operate on Windows, macOS, and Linux environments. These agents form the backbone of our telemetry and device management capabilities across thousands of managed endpoints.
 

Role Overview:
 As a Client Engineer, you'll build reliable, high-performance system services and daemons that power Flamingo's open-source infrastructure for MSPs. You will work closely with backend engineers to design, implement, and optimize cross-platform components responsible for device management, monitoring, and secure data exchange.
 

Key Responsibilities:

• Develop cross-platform agents, daemons, and background services in Rust for Windows, macOS, and Linux
• Work with low-level system APIs and platform-specific tools: Win32 API, LaunchAgents/Daemons, systemd, and more
• Integrate services with backend infrastructure via HTTP, WebSockets, and NATS
• Write secure, asynchronous, and performant Rust code using Tokio, Serde, and Tracing
• Optimize real-time data processing, message handling, and network performance
• Collaborate with backend and platform teams to ensure reliability, observability, and security across deployments
• Contribute to our open-source projects by writing clean, documented, and community-friendly code

Our Stack:

• Language: Rust (1.8x+)
• Core Libraries: tokio, serde, anyhow, tracing, thiserror
• Networking: reqwest / hyper (HTTP), tokio-tungstenite / warp (WebSockets), nats.rs (NATS)
• Platform APIs:
  • Windows – Win32, COM, Registry
  • macOS – LaunchAgents, Daemons, Keychain
  • Linux – systemd, journal, epoll, nix crate
• Tooling: Git, GitHub, cross-platform builds

Must-Have:

• Strong proficiency in Rust, including async programming and ownership concepts
• Experience developing system-level software for at least one major OS (Windows, macOS, or Linux)
• Familiarity with platform APIs (e.g., Win32 API, systemd, macOS Daemons)
• Solid understanding of networking (TCP/UDP, WebSockets, HTTP)
• Experience with multi-threaded and asynchronous programming
• Attention to security, performance, and code maintainability

Nice-to-Have:

• Experience with NATS, message brokers, or real-time telemetry systems

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.
