Job description

Our mission is to transform international supply chains to be more resilient by helping logistics companies realize the full potential of their data. We cater to both shipping lines and cargo airlines. This covers 90% of the world trade volume that travels via ocean and 35% of world trade value that travels via air. We use proprietary machine learning algorithms and real‑time external market data (such as economic indices, marine weather, satellite‑based data, etc) to predict how much cargo will be shipped when it will arrive and deliver actionable insights.

We are excited to be a fast‑growing team of software engineers, data scientists and industry experts. Based out of Singapore, we’ve been building together since 2018, and are backed by some of the leading investors including Wavemaker Partners, Entrepreneur First, SGInnovate and Investigate VC.

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.

• Team Player: You have experience working in a diverse, dynamic and cross‑cultural team. This role is an opportunity to drive engineering excellence within the team and participate in key architectural discussions.
• Empathetic Communicator: You can communicate nuanced ideas clearly, from real‑time remote brainstorming to explaining a technical decision in writing. You may be opinionated, but in disagreements, you engage thoughtfully with other perspectives and can compromise when needed.
• Tech Stack: Ideally you are proficient with Python‑based backend programming, web frameworks like Flask, Amazon Web Services. You are able to design RESTful APIs and are aware of best practices. Experience with Docker, Git, Elasticsearch, Spark, CI/CD is a plus.
• You’ve been an early engineering hire at a startup who has built a technical product from scratch up to scale. We’d love to hear your learnings from doing that.

What’s In It For You:

• Globally distributed, remote‑first flexibility: Work with a fully distributed team across Asia and Europe, built on trust, accountability, and collaboration. Our diversity of perspectives fuels innovation and keeps us curious.
• Tech‑first team: You’ll work with like‑minded individuals who share a passion for solving difficult problems using technology.
