• Design, develop, and maintain scalable backend services using Python (FastAPI, Temporal) and Go lang using modern architectural patterns. • Implement well-structured REST and asynchronous APIs driven by OpenAPI specifications, ensuring contract consistency and backward compatibility. • Evolve the existing proof-of-concept into robust, production-ready components with clear boundaries, interfaces, and observability. • Design and optimize data models using PostgreSQL for relational data and Qdrant for vector-based search. • Ensure performance, scalability, and consistency across high-volume workloads involving document metadata, embeddings, and structured content. • Collaborate with AI engineers to design retrieval and indexing mechanisms for hybrid RAG workflows. • Work with AI engineers to expose model orchestration and retrieval layers through well-defined interfaces. • Collaborate with front-end and QA engineers to ensure API usability, performance, and testability. • Contribute to the system design discussions and translate product requirements into reliable backend services. • Ensure secure, compliant, and maintainable implementations, including authentication (OIDC/SSO), role-based access control (RBAC/ABAC), and data protection principles. • Apply best practices in test-driven development, code reviews, and CI/CD integration. • Implement observability through structured logging, metrics, and tracing (OpenTelemetry, Prometheus, Grafana). • Profile and optimize performance across API endpoints and data flows. • Contribute to automation, deployment, and release management using GitHub Actions and Argo CD. • Propose architectural improvements, automation, and tools to streamline development workflows. • Help document design decisions (RFCs, ADRs) and maintain high standards for maintainability and reliability.

• Take ownership of complex backend features using Node.js and TypeScript. • Act as a solution architect within your domain, ensuring the platform remains scalable and secure. • Work closely with a hybrid team of senior engineers and augmented international teams. • Maintain high-velocity output to meet a demanding and fast-paced product roadmap.

• Design, build, and ship customer-facing features across our CI/CD platform • Work on backend systems and services that support Flutter and other mobile ecosystems • Collaborate closely with product, design, and other engineers to shape solutions • Engage with customer feedback to solve real-world developer problems • Take ownership of features from idea to production in a fast-moving environment • Depending on your experience, this role can include technical leadership, architectural decisions, and mentoring

• Architect and Build: Design and implement critical systems, including consensus mechanisms, transaction reordering processes, and state management. • Innovate: Address complex challenges in distributed systems and cryptography to enhance scalability and robustness. • Collaborate: Work closely with the founding team to iterate rapidly based on feedback from our integration partners and other members of the blockchain ecosystem. • Set Standards: Establish benchmarks, tools, and best practices to ensure the system is efficient, scalable, and developer-friendly.
