Role Overview: We are seeking an experienced Software Architect to lead the design and evolution of highly scalable, secure, and resilient AWS serverless platforms. This role is ideal for a senior technologist who thrives at the intersection of architecture, hands-on implementation, and technical leadership, and who brings a strong point of view on cloud-native design tradeoffs. You will act as an architectural steward for our backend systems, ensuring they align with the AWS Well-Architected Framework across operational excellence, security, reliability, performance efficiency, and cost optimization. Responsibilities Responsibilities: • Own and evolve the backend architecture for serverless, event-driven systems built on AWS Lambda, API Gateway, DynamoDB, and EventBridge. • Define and enforce architectural standards, reference patterns, and best practices aligned with AWS Well-Architected principles. • Lead architectural reviews, design discussions, and trade-off analyses across teams. • Serve as a technical authority and mentor for senior and mid-level engineers. • Design and oversee GraphQL API architectures using TypeScript, with a focus on schema governance, versioning, and long-term maintainability. • Guide data modeling strategies, including DynamoDB single-table design, access patterns, and scalability considerations. • Establish resilient, observable, and fault-tolerant systems with clear SLOs and recovery strategies. • Drive Infrastructure as Code practices using AWS CDK, enabling repeatable, auditable environments. • Embed monitoring, logging, alerting, and automated remediation into system designs. • Lead root cause analysis for complex production incidents and drive systemic fixes. • Partner with DevOps and product stakeholders to improve deployment safety, release velocity, and operational maturity. • Architect systems with defense-in-depth security, least-privilege access, and compliance-aware designs. • Continuously assess and improve system performance, scalability, and cost efficiency. • Ensure designs are aligned with regulatory and compliance requirements where applicable (e.g., FedRAMP). • Work cross-functionally with product, frontend, and platform teams to translate business requirements into durable technical solutions. • Influence roadmap decisions by clearly articulating technical risks, constraints, and long-term implications. • Contribute to engineering culture through thoughtful code reviews, architectural documentation, and continuous improvement initiatives. Qualifications Qualifications: • 8+ years of professional experience in backend or platform engineering, with architect-level responsibility for production systems. • Deep expertise in TypeScript and modern backend application design. • Strong hands-on experience with AWS serverless architectures (Lambda, API Gateway, DynamoDB, EventBridge). • Proven experience designing and governing GraphQL APIs at scale. • Advanced understanding of distributed systems, data modeling, and event-driven architectures. • Extensive experience with Infrastructure as Code (AWS CDK preferred). • Demonstrated ability to diagnose and resolve complex system failures through structured root cause analysis. • Strong familiarity with CI/CD pipelines, version control strategies, and automated testing practices. • Experience operating in Agile environments with cross-functional teams. What We’re Looking For: • Someone who is detail-oriented and comfortable taking ownership of features from design to deployment. • A developer who enjoys solving complex architecture challenges in a cloud-first environment. • A collaborative team member who values quality, reliability, and maintainable code. • A team member that reflects our foundational behaviors: Client service, flexibility, respect, stewardship, commitment, initiative, and teamwork.
