What you will do

• Design, develop, test, deploy, operate, and evaluate modules for user incentives, experience improvements, business automation, and retention.
• Build and maintain financial benefit systems covering rule execution, monetary calculations, disbursement, state transitions, idempotency, consistency, compensation, reconciliation, and auditing.
• Productionize AI applications and user experiences, improving output quality, responsiveness, stability, and operating costs.
• Design and iterate on AI Agents and agentic workflows integrating models, tools, knowledge retrieval, troubleshooting, operational assistance, and internal business systems.
• Establish evaluation, observability, safety, context and state management, recovery, budget controls, human intervention, permission boundaries, and sensitive-data protection for AI workflows.
• Build reusable AI-assisted engineering workflows for requirements analysis, development, testing, code review, and troubleshooting.

Requirements

• Bachelor’s degree or above in Computer Science or a related field, plus at least four years of backend development experience; Go or Java is acceptable.
• Strong programming fundamentals in concurrency, memory management, performance optimization, and complex issue troubleshooting.
• Experience with distributed systems and core business modules, including concurrency conflicts, idempotency, duplicate message consumption, cross-service consistency, timeouts, and failure recovery.
• Proficiency with RPC frameworks, caches, message queues, and relational databases, including their use cases and reliability limitations.
• Core requirement: experience using AI coding tools for requirements decomposition, system analysis, coding, testing, and code review while validating outputs and maintaining engineering quality.
• Core requirement: hands-on experience developing and deploying AI/LLM capabilities in real-world scenarios, with the ability to explain problem definition, contribution, trade-offs, and outcome validation.
• Mandatory: hands-on development of fund- or monetary-value systems such as commission rebates, settlement, reconciliation, payments, accounting ledgers, vouchers, promotional credits, or subsidies, including monetary precision, duplicate disbursement prevention, failure compensation, or financial reconciliation.
