Senior Fullstack Engineer (backend focus)

Aracor is on a mission to build a world-class product that will redefine dealmaking. The Senior Fullstack Engineer will design, build, and scale the backend architecture for Aracor's AI-driven legal platform, ensuring reliable APIs and efficient service orchestration.

Responsibilities:

• Design, develop, and maintain scalable backend services using Python (FastAPI, Temporal) and Golang 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
