• Design and develop scalable, fault-tolerant backend services following Microservices and Hexagonal Architecture principles. • Deploy and manage containerized applications on Azure Kubernetes Service (AKS) using Docker and Azure-native infrastructure. • Collaborate with Product and Engineering teams to translate business requirements into scalable technical solutions. • Create architecture documentation, estimations, and user stories that support Agile delivery processes. • Ensure platform performance, security, reliability, and SLA compliance through engineering best practices. • Mentor and guide engineers while promoting ownership, quality, and technical excellence. • Lead and participate in code reviews to ensure scalability, maintainability, and adherence to engineering standards. • Contribute to observability, incident response, and continuous platform improvement initiatives. • Influence technical roadmaps and contribute to architecture, tooling, and platform decisions. • Support operational excellence initiatives across backend systems and cloud environments.

• Develop and implement business modules and core frameworks in Java • Identify and resolve technical issues in Java backend systems to ensure optimal performance and stability • Collaborate on the architecture and design of financial systems, including core modules • Collaborate with cross-functional teams to ensure the rationality of system architecture and safeguard project quality and progress • Participate in code reviews and provide constructive feedback • Continuously improve and optimize existing systems for performance, scalability, and reliability

• Work on backend services and APIs that connect the user-facing platform with lower-level infrastructure services and automation components • Help extend existing Python APIs, implement new platform features, improve RBAC and multi-tenancy capabilities • Support integrations with infrastructure services • Work in a mixed engineering team, contributing both to new functionality and to improving code quality, maintainability, documentation and delivery standards

• Build and own backend services: Design and implement features across both Rails-based services and Go microservices — from API contracts through deployment and monitoring. • Support the migration to microservices: Help decompose the Rails monolith into well-scoped, independently deployable services, contributing to architectural decisions about what to extract and how. • Power internal tooling APIs: Build and maintain the backend APIs that Back Office operators depend on for real-time decisioning — projection management, risk dashboards, alerting, and member operations. • Own technical delivery: Lead the design and implementation of complex features end-to-end, from product requirements through production deployment. • Drive system reliability: Diagnose and resolve performance bottlenecks, optimize database queries, and improve resilience of backend systems under load. • Define technical direction: Propose and drive architectural decisions for your team's services, evaluating tradeoffs and communicating recommendations clearly to engineers and stakeholders. • Mentor and elevate: Provide hands-on mentorship to Software Engineers I, II, and III through code reviews, pairing, and technical guidance. • Improve engineering practices: Advocate for and improve best practices around code quality, testing, observability, and deployment for the team. • Collaborate cross-functionally: Work closely with Product Managers, QA, and other engineering teams to translate operational goals into well-scoped technical solutions. • Participate in on-call rotation: Share responsibility for production incidents, contributing to root cause analysis and long-term reliability improvements.
