Software Engineer (Backend Focus)

Be part of something.

Every time a shipment moves Yojee makes it visible intelligent and efficient.
Were not building dashboards for clicks.
Were building technology that actually moves the world optimising how freight flows across air ocean and road.

Logistics is a global industry with real operational complexity. With MOSAIC and TCMS we are building products that handle real-time events high data volume and mission-critical workflows.

If youre an experience backend engineer executing reliably today and ready to start owning more pushing back on briefs supporting teammates and influencing how things get built this role is for you.

The Opportunity

Were hiring an experienced Software Engineer (Backend focus or Fullstack) to join a product squad and deliver real backend work from day one: distributed systems real-time freight events data orchestration and the reliability work that keeps mission-critical workflows alive.

Youll work closely with product design and other engineers as aproduct engineer: someone who owns the why as much as the what. Youll deliver well-scoped services across Elixir / Phoenix distributed systems real-time freight events data orchestration and reliability work that keeps mission-critical workflows alive and help shape the patterns abstractions and quality bar the wider engineering team relies on.

The role is set up for growth: youll be given progressively more ambiguous problems expected to take initiative beyond the assigned ticket and supported to grow into end-to-end ownership over the next 612 months.

This isnt brochureware or content management. Youll be working on enterprise-grade data-intensive applications where performance and state management matter to global logistics networks.

Agentic AI is a real part of how we work across our SDLC and inside the product. We use coding agents agentic prompting and MCP-based tooling in day-to-day delivery and were building native agentic AI into the platform itself not a bolted-on chatbot. Youll grow your craft inside that environment not separate from it.

What Youll Do

• Design and Implement Services in Elixir / Phoenix: Build reliable services that handle real-time freight events and high-volume data. Make thoughtful trade-offs between speed correctness and maintainability.
• Show Early Ownership: Take responsibility for completing work without leaving loose ends. Follow through after release verify what shipped behaves as expected and start thinking about how your work fits the broader feature and system not just the ticket.
• Contribute to Architecture Decisions: Review specs challenge assumptions and align before coding. Raise feasibility and trade-off questions early when theyre cheapest to resolve.
• Write Production-Ready Code and Reviews: Clean well-tested consistent with team standards. Give useful feedback in code review catch real issues including in AI-generated code not just style nits.
• Enforce Standards via Tooling: Use and improve our tooling (formatter Credo Dialyzer/Dialyxir CI checks) to keep Elixir best practices and code style consistent across modules automated where possible deliberate where not.
• Operate What You Build: Participate in deployments troubleshooting and performance tuning. Work hands-on with our CI/CD pipelines and infrastructure-as-code not just consume them.
• Use AI Deliberately: Use coding agents agentic prompting and MCP-based tooling as a real part of how you deliver. Apply the same critical eye to AI output as to any other code.
• (If Fullstack) Implement Frontend Elements: Build UI in React / TypeScript maintain consistency of patterns across modules and support genuine end-to-end feature delivery.

What Youll Bring

• 46 Years of Experience: Building and shipping complex production-grade backend systems professionally with at least one or two systems you can speak to in depth including how they failed and what you did about it.
• Elixir Experience: Commercial or substantial open-source / personal projects. Phoenix strongly preferred. Other BEAM-family or functional languages (Erlang Scala OCaml Gleam) considered if Elixir adoption is realistic for you.
• Distributed / Event-Driven Foundations: Solid understanding of distributed systems and event-driven architectures concurrency message passing consistency trade-offs failure modes.
• Relational Database Depth: Comfortable modelling querying and reasoning about performance and consistency. PostgreSQL ideal.
• Real Infrastructure Experience: Hands-on with AWS Docker CI/CD pipelines and infrastructure-as-code not just familiarity. Youve built or meaningfully extended CI/CD or IaC and can reason about whats happening in production.
• AI-Assisted Delivery: Practical experience using coding agents agentic prompting and MCP-style tooling to ship real work. You can articulate where AI accelerates you where it misleads you and how you validate its output.
• Initiative Beyond the Ticket: A track record of going slightly past the brief fixing the adjacent thing raising the trade-off no one asked about leaving the codebase a little better than you found it.
• Collaboration and Judgement: Think and communicate before acting. Comfortable working through ambiguity with alignment not cowboy coding. Honest about what you know and dont know.
• Communication: Clear friendly fast-moving and direct. Comfortable working closely with product design and other engineers and translating technical context for non-engineers.

Bonus Points For

• Experience with React / TypeScript if youre applying for the fullstack variant
• Experience building real-time or high-load systems
• Exposure to logistics supply chain tech or third-party integrations (ERPs TMSs telematics)
• Open-source contributions particularly to tooling libraries or BEAM-ecosystem projects
• Comfort working across multiple services and modules
• Experience in greenfield projects or scaling-stage startups where youve had to set small patterns yourself

Why Youll Love Working Here

A Great Place to Work (Literally): Enjoy in-person collaboration 4 days per week in our Sydney CBD office in the heart of the city close to great food coffee and transport.

Real Engineering Real Impact: Youll work on meaningful product challenges with direct line of sight to operational users concurrency real-time events data orchestration and clear UI all matter here.

Shape Whats Being Built: Our architecture is established but not rigid. Theres room to grow into bigger problems as you progress and to influence patterns as you do.

Small Team Big Autonomy: No bureaucracy. Direct line to product design and leadership. You get context ownership and visibility from day one.

Growth With Meaning: This is a place for builders who want to leave a mark on something real. We use a published levels framework so progression on craft scope and leadership is a real conversation not a guessing game.
