You will join the BMP Retail team, working at the intersection of core software engineering and AI integration. Rather than training AI models from scratch, you will focus on driving the adoption of AI-first engineering practices, Agentic AI, Spec-Driven Development (SDD), and vibe coding methodologies across multiple lines of business. In this role, you will play a key part in designing and building intelligent, scalable, and production-ready backend services and automated solutions that accelerate software delivery while ensuring quality, governance, and compliance. You enjoy solving complex business challenges, leveraging software engineering fundamentals alongside modern AI tools, and translating abstract ideas into structured specifications and practical solutions. If you are motivated by innovation, automation, and delivering measurable business impact in a collaborative and international environment, we would love to hear from you. What you do * Collaborate with product owners, architects, and business stakeholders to understand business needs, translating them into clear software solution requirements and success criteria. * Design end-to-end AI-enabled software solutions, defining domain models, API contracts, data schemas, decision rules, and policies that serve as the foundation for development and automation. * Embrace and champion vibe coding practices, leveraging high-level AI prompt-driven development and rapid iteration cycles to quickly turn ideas into functional prototypes and production-ready code. * Drive the adoption of Spec-Driven Development (SDD) practices, using specifications as a single source of truth to enable AI-assisted generation, validation, testing, and documentation of software solutions. * Develop, integrate, and maintain AI-powered tools, agents, and orchestrators that improve efficiency, quality, and speed throughout the software delivery lifecycle. * Design and implement robust backend integrations with internal APIs, databases, search platforms, and enterprise services while ensuring secure access control and governance standards. * Deliver scalable backend services, APIs, data layers, and frontend capabilities that support BMP Retail products and business processes. * Continuously improve AI agents, prompts, specifications, evaluation frameworks, and guardrails to enhance solution quality, reliability, and business value. * Participate in architecture discussions, specification reviews, code reviews, testing activities, demonstrations, and troubleshooting of complex technical issues. * Contribute to effort estimation, feasibility assessments, and technical decision-making within agile development teams. * Promote software engineering excellence through best practices, documentation, automation, and knowledge sharing.
