Senior Full-Stack Engineer

About The Opportunity

At AI/R Avenue Code, we are passionate about transforming businesses through technology. We are a leading end-to-end development consultancy for digital transformation across various markets, growing sustainably since day one. We believe that great results are born from strong relationships. Our team combines technical expertise, collaboration, and a welcoming approach to work that makes all the difference.

We are looking for a Senior Full Stack Software Engineer to drive key initiatives within our Supply Chain Technology team, focusing directly on our core ERP modernization and Order Management program. In this role, you will lead workstreams across sales order intake, orchestration, load planning, and multi-system integrations connecting warehouse operations, carriers, and financial platforms. You will work with significant autonomy, leverage AI-assisted engineering practices to accelerate delivery to production standards, and collaborate cross-functionally with distributed engineering teams.

Responsibilities

• Architect, build, and deliver scalable end-to-end solutions for sales order intake, orchestration, and order lifecycle management.
• Design and implement resilient integrations with surrounding ecosystems (carriers, warehouse management systems, order sources, and finance) across REST APIs, event streams, and batch processing.
• Build clean, responsive, and intuitive user interfaces using React to support internal order operations and operational workflows.
• Write robust backend services and optimize relational database models and queries using Go or Java and SQL.
• Own deliverables end to end from technical design and system architecture through coding, comprehensive testing, production rollout, and knowledge transfer.
• Incorporate AI-assisted engineering tools actively into design refinement, coding, and code validation while ensuring high production standards.
• Proactively communicate project status, identify architectural bottlenecks, and surface delivery risks early.

Required Qualifications

• Proven track record taking complex, distributed software systems from technical design through to production deployment.
• Deep hands-on experience in supply chain technology or enterprise order systems, specifically sales order intake, order lifecycle orchestration, and ERP extensions.
• Advanced backend development experience in either Go or Java, with strong relational database design and SQL optimization skills.
• Hands-on frontend development experience building modern web applications using React.
• Solid experience designing and maintaining enterprise integrations across REST APIs, event-driven architectures, and batch pipelines.
• Active, daily practical application of AI development tooling (e.g., design synthesis, AI-assisted coding, and automated validation workflows) with concrete examples of driving delivery velocity and code quality.
• High degree of autonomy with the ability to own workstreams end to end, make sound architectural trade-offs, and coordinate directly with external teams.

Nice To Have Skills

• Experience with durable execution and workflow orchestration engines such as Temporal.
• Hands-on experience with Apache Kafka or equivalent event-streaming platforms.
• Practical experience with AWS cloud infrastructure and managed services.
• Familiarity with Warehouse Management Systems (WMS) integration patterns and protocols.
