Global logistics is one of the most complex systems on earth — and we are on a mission to simplify that.
Yojee is building the digital nervous system for freight forwarding, customs brokerage and carrier operations across air, ocean and road.
With MOSAIC (freight forwarders) and TCMS (carriers & shippers), we’re connecting every movement, event, document, and workflow into one integrated ecosystem.
The architectural decisions we make in the next 12–18 months will define the backbone of the company and the global landscape of international logistics for years.
This is where you come in.
The Role
Yojee is looking for a Staff
Software Engineer who can shape the technical direction of our platform, guide engineering teams, and build scalable, maintainable systems that stand the test of time.
You will work across MOSAIC, TCMS, integrations, event processing, and front-end architecture patterns — ensuring coherence, reliability, and effectiveness across modules.
This is a hands-on role. You will design, code, and drive best practices.
You’ll excel here if you:
- think in systems and boundaries, not only features
- enjoy solving real-world engineering problems
- communicate clearly with engineers, product, and leadership
- balance pragmatism with long-term architectural integrity
- understand modern distributed systems, data flows, integration patterns, and event-driven design
- care deeply about quality, consistency, and teams working in sync
What You'll Be Responsible For
Architecture & System Design
- Define and evolve the technical architecture across multiple domains
- Set standards for service boundaries, communication patterns, data flows, and integration logic
- Bring clarity to complex system interactions and ensure architecture is resilient and scalable
- Review and influence system design across squads
- Deep understanding of Database Design & Distributed System
Technical Leadership
- Partner with engineering teams to design robust, maintainable solutions
- Provide hands-on mentoring and architectural guidance
- Conduct design reviews and improve engineering decision-making
- Establish patterns, frameworks, and conventions that drive consistency
Hands-On Engineering
- Contribute to backend services using Elixir/Phoenix
- Support frontend architectural decisions (React/TypeScript/LiveView)
- Prototype, spike solutions, and validate architecture choices
- Collaborate on deployment, reliability, and observability improvements
Cross-Functional Alignment
- Work closely with Product to shape technical direction and feasibility
- Collaborate with DevOps/SRE to ensure reliability, performance, and scalability
- Bring proactive thinking around risks, dependencies, and system evolution
- Translate complexity into simple concepts for decision-makers
What You’ll Bring
Must-Have
- 7+ years engineering experience with significant architecture ownership
- Strong experience designing distributed or event-driven systems
- Deep experience with Elixir/Phoenix OR willingness to lean in quickly with functional programming experience
- Experience defining and maintaining service boundaries and system contracts
- Strong communication skills — able to influence without ego
- Track record of elevating engineering quality and architectural discipline
Nice to Have
- Experience in logistics, supply chain, or integrations-heavy products
- Familiarity with React/TypeScript or frontend architectural patterns
- Knowledge of high-availability and high-throughput systems
- Experience with performance tuning, observability, and resilience engineering
- Experience guiding engineering teams through scale-up stages
