• Design, build, and maintain robust backend services and RESTful APIs that power Toku’s omnichannel communication platform. • Build and maintain event-driven backend systems to support asynchronous workflows across messaging, notifications, and voice services. • Independently design microservices, define service boundaries, and reason about scalability, latency, data consistency, and architectural trade-offs. • Rewrite and migrate existing backend services (currently implemented in TypeScript) into Go and newer backend architectures. • Develop cloud-native backend systems on AWS, working closely with the infrastructure team to clearly articulate service requirements and operational needs. • Design and work with SQL-based data models, ensuring performance, correctness, and alignment with real product usage; contribute to NoSQL usage where appropriate. • Support communication and notification services across WhatsApp, SMS, email, and voice channels, handling communication metadata at scale. • Own backend services in production, including reliability, performance, observability, and continuous improvement. • Write clean, maintainable, and well-documented backend code, and participate actively in code reviews and technical design discussions. • Take initiative and drive backend problems through to solutions independently, collaborating effectively with peers across engineering.

• Develop, test and iterate on product features spanning frontend (React, Next.js, TypeScript), backend (Node.js, PostgreSQL, Hono), and cloud infrastructure (Azure) • Work closely with product, design, QA, and business teams to translate requirements, mockups and process flows into production-ready features • Design and build integrations with third-party services such as social media, eCommerce, artificial intelligence and financial services • Follow best practices for code quality, reliability, security, and scalability • Implement automated integration tests (Jest) that adhere to test plans • Monitor live applications and troubleshoot issues post-deployment.

• Design, implement, and maintain database infrastructure using StatefulSets, Operators, and Helm charts to ensure databases are reliable, self-healing, and scalable. • Own the deployment lifecycle for database clusters by managing version control for Helm charts and configuration templates. • Support and administer production database systems by proactively instrumenting and monitoring performance, security, and availability within the containerized environment. • Perform zero-downtime upgrades and migrations for major and minor releases, developing and maintaining Helm hooks and custom scripts to automate complex stateful operations. • Develop and maintain automation tools and scripts (Bash, Python) specifically focused on simplifying Kubernetes management tasks, such as provisioning users/secrets and monitoring cluster state.
