Backend Engineer

About the role

Portcast has already been used by global freight forwarding companies, manufacturers and cargo airlines. Our customers trust us to deliver fast, reliable and secure predictions to unleash greater profitability and realise the true value of their logistics data. We want to continue earning their trust, while also scaling and delivering new products to serve their needs. As our Backend Engineer, you will be reporting directly to our Engineering Manager and will work closely with our Product team to develop new products, scale existing ones and manage deployments and architecture. You won't just take tickets here. You'll dig into how the system actually works, ask why before how, and chase a problem past the surface to the real cause. Curiosity isn't a nice-to-have on this team, it's how we build.

Responsibilities

• Design, build and maintain APIs, services and systems and debug production issues across multiple levels of the stack.
• Collaborate closely with our Business, Product and Data Science teams to understand and solve customer pain points at scale.
• Design, Develop, Implement and Deploy enterprise level, high availability web application platforms, with support from the design team at Portcast.
• Create a technology infrastructure that functions well at scale. You will design and improve the system architecture.
• Own end-to-end the design AND implementation of how our product handles real-time data at scale, from event ingestion across dozens of carrier sources, through data normalization, through ML-powered risk and ETA models, to the user-visible recommendations our enterprise customers act on.
• Build features customers actually use, harden internal tooling the team relies on, and create the alerting and monitoring surfaces that catch issues before customers do. You're a builder first, with the judgment to know what's worth building.
• Make architecture trade-offs explicit and defensible.
• Instrument what you build, find real bottlenecks, and pick fixes that survive the next 10× of growth, not just the next sprint. You measure before you optimize, and your numbers are reproducible.

Requirements

• Bachelor's or Master's Degree in Computer Science, Electrical Engineering or equivalent work experience in the field.
• Work Experience: Minimum 4+ years of experience in a technical role designing, developing and releasing technical solutions and building production systems.
• First Principles Thinker: When you explain a past decision, the trade-offs come out before the tools. You name the constraint, the alternatives you considered, and why you picked what you picked. You don't reach for a new framework when a tighter use of an existing tool would do the job.
• Curious by Default: You dig deeper instead of following instructions to the letter. When something in the system surprises you, you chase the why, not just the fix. You treat every layer of the stack as something worth understanding, and you ask the good questions early.
• You use AI tools (Copilot, Cursor, Claude, etc.) where they make you faster, and you know exactly where they fall short. You read what they produce, you don't just paste it. You can defend a code path the AI
