Advanced Backend Engineering & AI Automation

# Lead Backend Engineers & AI Automation Architects (Enterprise-Grade) ## Project Overview We are the engineering team behind RailCall, a governance-first automation layer for AI-driven workflows. We are seeking elite backend engineers and systems architects to help us build out advanced, enterprise-grade local agent programs and secure integrations. We have secured a $10,000 development budget for this specific architectural phase. We are looking to award milestone contracts to developers who can solve complex orchestration problems using our cryptographic execution engine. ## Core Development Focus Rather than simple API wrappers, this phase is dedicated to heavy backend engineering: **1. Secure Local Agent Programs** Building complex, autonomous agent workflows that execute strictly on local compute environments without leaking data to public cloud APIs. **2. Cryptographic Airlock Integrations** Developing integrations that heavily leverage our `preview - approve - execute - signed receipt` loop, ensuring absolute auditability (Ed25519) for enterprise clients. **3. High-Complexity Workflows** Designing robust automations that handle rate limits, retry logic, and complex state management across multiple B2B tools (e.g., Salesforce, Jira, custom internal databases). ## Technical Requirements - All deliverables must run purely on **local compute** (`127.0.0.1`). - Implementations must generate verifiable **Ed25519 cryptographic receipts**. - You must have strong experience with API rate limiting, webhook orchestration, and security-first development. ## Application & Delivery Process ** IMPORTANT: This is an open bounty-style development sprint. To participate, please place a bid to register your interest, and then review the full technical architecture requirements on our official portal. All prize payouts and contracts will be awarded securely via milestones directly on this platform!** 1. **Place a bid** on this project to register your technical background. 2.
