We build and scale SaaS and web products, AI solutions, business automation and integrations, while keeping strong expertise in classic custom development and DevOps.

We are a lean team of 30+ specialists and prefer practical solutions, direct communication and measurable business results.

What you'll do

Your main focus will be working with qualified opportunities from Upwork and other channels and turning them into deals.

This is not a manual bidding position — lead sourcing and bidding are handled separately.

You will:

• Qualify incoming opportunities and research potential clients;
• Take over communication with promising leads;
• Run initial discovery calls independently;
• Understand business needs, scope, budget and timeline;
• Prepare initial commercial proposals and coordinate estimates with our PM/technical team;
• Manage follow-ups, negotiations and opportunities in CRM;
• Develop partnerships and referral relationships;
• Explore and test new acquisition channels: platforms, communities, networking events, agency partnerships, etc.;
• Systematize sales and partnership activities and track their results.

What we expect

• 2+ years in B2B IT Sales / Business Development;
• Experience selling software development, AI/automation or related technical services;
• Good understanding of Upwork mechanics and agency accounts;
• Ability to run qualification and discovery without bringing a developer to every call;
• Understanding of SDLC, MVP development and basic software architecture;
• Experience with commercial proposals, estimates and negotiations;
• Upper-Intermediate+ English;
• Ownership, initiative and strong follow-up discipline.

Tools

Experience with CRM, Upwork, Trello, Slack, Notion, Miro, Google Workspace and modern AI/research tools such as ChatGPT, Claude etc.

You don't need to know every tool — you need to be comfortable figuring things out.

What we offer

• Base salary + strong commission tied to results;
• Additional bonuses for closed deals;
• Existing lead sources and processes — you're not starting from zero;
• Direct access to founders, PMs and technical specialists;
• Freedom to test and develop new sales channels;
• Remote work;
• Paid vacation and sick leave.

We are a small team, so this isn't a role where your job ends with “I booked a call.”

We need someone who can pick up an opportunity, understand it, move it forward, involve the right people when needed — and turn it into business.

In this role, you will

• Own the full revenue funnel and its P&L from acquisition to repeat payments — accountable to ROAS LT0/LT7/LT30 targets and blended payback
• Develop and execute the revenue growth strategy across paid traffic (mobile + web), product growth, and monetization, owning channel mix, budget allocation, and scaling decisions
• Generate, prioritize, and validate growth and monetization hypotheses with Product and Tech, driving prioritization of Product Owner backlogs for growth work
• Lead A/B and multivariate testing across onboarding, activation, paywalls/coin-packs, and pricing

• Build revenue dashboards and a single source of truth for performance metrics, with shared metric definitions and transparency across teams

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.
