Software Engineer (Fullstack)

Build technology that moves the world.

At Yojee, we build software that makes freight visible, intelligent and efficient across air, ocean and road. Our MOSAIC and TCMS products handle real-time events, high data volumes and mission-critical logistics workflows.

We're looking for a senior product engineer with depth across backend and frontend. You'll own features from defining the problem through Elixir/Phoenix services and React/TypeScript interfaces to rollout and production health.

What you'll do

• Own outcomes: Work with product and design to define the right solution, deliver across the stack and verify its impact after launch.
• Raise engineering quality: Write well-tested, maintainable code; review others work, including AI-generated code; and shape architecture and standards.
• Build shared foundations: Improve patterns, components, CI/CD, performance and observability so the whole team works more effectively.
• Multiply your impact: Mentor engineers, explain technical trade-offs clearly and use coding agents, agentic prompting and MCP tooling deliberately.
• Own the User Problem: Operate as a product engineer — understand the user problem and business rationale behind features, use data to validate that what shipped actually works, and propose the right scope rather than executing the requested scope blindly.
• Use AI Deliberately: Accelerate good work with coding agents, agentic prompting, and MCP-based tooling — applied to backend and frontend alike. Recognise and manage the risk in your own work and in what you review.

What you'll bring

• 6+ years building and owning production web applications across backend and frontend.
• Backend Depth: Strong functional backgrounds experience (commercial or substantial open-source), considered if Elixir adoption is realistic for you. Solid understanding of distributed systems or event-driven architectures, relational databases (PostgreSQL ideal), and operational concerns (CI/CD, observability, performance).
• Frontend Depth: Strong React, TypeScript, JavaScript, and solid CSS fundamentals. Comfortable with state management, performance tuning, accessibility, and testing strategy in data-dense interfaces.
• Experience with complex, data-intensive enterprise applications, distributed or event-driven systems, relational databases and production operations.
• Sound product judgement and ownership: navigate ambiguity, challenge scope, raise risks and follow through.
• AI-Fluent Delivery: Practical experience using coding agents, agentic prompting, and MCP-style tooling across backend and frontend. You can articulate where AI accelerates you, where it misleads you, and how you validate its output.

Useful extras: Logistics or integration-heavy systems, real-time interfaces, data visualisation, design systems, open-source contributions or experience establishing patterns in a scaling team.

Why Yojee

Real operational impact. Small-team autonomy. Room to shape the architecture.

You'll work directly with product, design and leadership, use agentic AI throughout delivery and help build it into the platform. Our published levels framework gives you a clear path to grow in craft, scope and leadership.
