• Develop, enhance, and maintain backend services and APIs in Go supporting tools for plan comparison, provider and drug coverage information, and local enrollment help • Design and build REST APIs that power consumer-facing and internal healthcare marketplace features across a diverse set of consumers • Maintain consistent, well-documented API interfaces with a focus on reliability and backward compatibility • Write clean, well-tested code with a focus on performance, maintainability, and security • Support ongoing operations and maintenance of existing digital products alongside new feature development • Collaborate with frontend engineers, product managers, and stakeholders to deliver scalable backend solutions • Contribute to code reviews and help uphold engineering standards across the team

• Develop and maintain core framework and key software components for the Kraken trading engine, with a fous on the Aeron-based messaging transport layer • Design and implement low-latency, high-availability messaging solutions across unicast, multicast, and IPC transport paths • Tune and profile the full system stack — CPU pinning, NUMA topology, kernel bypass, receive buffer sizing — to squeeze latency out of production infrastructure • Build and extend Aeron Archive integrations for durable message replay and stream persistence • Build and design solutions that mitigate risk, implement security, and protect both systems and data • Write reusable, testable, and efficient code • Collaborate with cross-functional teams and contribute to product roadmap accomplishment • Work collaboratively on a distributed team, leveraging soft skills to effectively communicate and engage with stakeholders

• Design and ship AI-powered features end to end. You own quality, latency, and cost. • Build backend services and APIs that hold up under real load. • Instrument what you ship, watch the numbers, fix what's wrong. • Review code and designs critically. Push back when something doesn't add up. • Help taking prompt, retrieval, and agent changes from experiment to production. • Live the mission: inspire and empower others by genuinely caring for your own wellbeing and your colleagues. Bring wellbeing to the forefront of work, and create a supportive environment where everyone feels comfortable taking care of themselves, taking time off, and finding work-life wellness.

• Lead the modernization effort by migrating legacy SOAP and WCF APIs to RESTful services using .NET Core, ensuring high performance, scalability, and maintainability. • Design and implement scalable microservices architectures that integrate seamlessly with existing Supply Chain Management systems. • Develop REST adapter layers to facilitate smooth communication between legacy systems and new services. • Architect and implement secure authentication and authorization mechanisms using OAuth 2.0, OpenID Connect, Multi-Factor Authentication (MFA), and JSON Web Tokens (JWT). • Create and maintain comprehensive OpenAPI (Swagger) specifications to document APIs clearly and facilitate collaboration. • Apply the Adapter design pattern and develop file-based interfaces to support legacy system integration and IVR system connectivity. • Collaborate closely with internal development teams, QA, and DevOps to ensure smooth CI/CD pipeline integration and automated deployments. • Participate in code reviews, mentor junior developers, and promote best practices in backend development and security. • Troubleshoot and resolve complex technical issues related to backend services and integrations. • Stay current with emerging technologies and industry trends to continuously improve backend architecture and development processes.
