Role Overview

You will develop distributed, transactional backend systems across cryptocurrencies, fintech, and real money gaming domains. These systems handle high volumes, are multi-tenant, and operate in real time. Accuracy is critical due to direct impact on balances, payments, and player-related decisions. Responsibilities span multiple products in conjunction with business priorities, requiring adaptable ownership of backend services implemented in Go.

Key Responsibilities

• Transform business goals and constraints into clearly defined, prioritized, and deliverable tasks.
• Architect and build distributed Go services managing high-volume transactional workloads, integrating payments, diverse providers, and internal platforms.
• Explicitly define and uphold strict correctness guarantees, especially where transaction and balance accuracy is mandatory.
• Leverage an agentic engineering process that encompasses context setting, task decomposition, execution, and verification to produce quality outputs.
• Create frameworks and safeguards such as contextual constraints, automated testing, and checks to enable contributor collaboration without diminishing system quality.
• Maintain operational responsibility for deployed systems—monitor failure modes, diagnose issues, and implement fixes promptly.

Required Qualifications

• Advanced expertise in Go programming language applied to large-scale, transactional production systems.
• Strong judgement in designing and operating multi-tenant, event-driven architectures and queue-based systems with awareness of associated failure risks.
• Experience with cloud-native technologies and a commitment to reliability, observability, and security best practices.
• Established agentic engineering methodologies that handle ambiguous inputs, systematically decompose work, enforce behavior verification, and prevent unvalidated code from reaching production.
• Proven ownership from end-to-end: leading from an undefined objective to delivering and managing a live system independently.
• Ability to make informed decisions amidst uncertainty by balancing objectives, constraints, and stakeholder insights; escalate only non-reversible matters.

Preferred Experience

• Background in fintech, real money gaming, or other high-traffic consumer services involving financial transactions.
• Familiarity with rules engines, real-time scoring, or automated decisioning platforms.
• Experience designing APIs tailored for multi-tenant or white-label services.

Role Clarifications

• This is an individual contributor position without direct reports or leadership responsibilities.
• This role does not involve directing architectural decisions for others.
• It requires self-driven prioritization rather than working against a pre-defined squad backlog.
• You will fully own system development including verification and production readiness without delegation.
• Agentic approaches to engineering are fundamental and continuously applied, not optional enhancements.

Work Culture

Expect a mature, purpose-driven, and low-ego environment valuing clarity, outcome-focused delivery, and balanced pace without chaos. You will collaborate with some of the top experts who share your commitment to technical excellence.
