高级机器学习工程师
Senior Machine Learning Engineer
Portcast 是一家位于新加坡的物流科技初创公司，由风险投资支持，帮助货运代理将数据转化为更好的决策和可衡量的业务影响。
Portcast 使用人工智能来揭示运输异常、成本风险以及正确的行动方案，帮助团队关注需要他们注意的运输任务，控制货运成本，并自信地做出采购决策。我们的愿景是成为每票运输中异常管理和利润提升的 AI 数据与智能层。
成立于 2018 年，由领先的科技投资者支持，我们正在为一个正处于数字化转型关键转折点的行业打造解决方案。我们的软件工程师、数据科学家和物流专家团队正致力于构建帮助货运代理保护利润、提高运营效率并差异化其服务的技术。
关于该职位：
我们正在寻找一位高级机器学习工程师，能够从问题定义、模型构建和部署到生产环境，全程负责解决方案。这是一个注重实战、以业务为导向的角色，在精简的团队中工作：你将构建推动客户实际成果的 ML 和 AI，就成本、规模和影响做出务实的判断，而不仅仅是模型准确性。
我们的模型（如预测到达时间）只是整个方案的一部分，而不是全部。你将全程负责一些产品，并为其他产品做出贡献，同时根据哪些能推动业务发展来决定哪些值得开发。你将与我们的数据、工程和产品团队紧密合作，将一些定义不明确的问题，有时甚至没有干净的基础数据，转化为已上线的功能。如果你喜欢在模糊环境中解决问题，并直接看到你的工作推动业务发展，而不是在大型实验室中进行漫长的科研周期，那么你会在这里很适合。
你将负责：
- 全程负责 ML 和 AI 解决方案：定义问题、构建模型、部署并运行于生产环境（MLOps）。你负责整个生命周期，而不仅仅是建模部分。
- 全程负责一些产品，并为其他产品做出贡献，考虑业务成果、成本和规模，以及模型性能。
- 能够从粗略的构想而非完整的规格书中开始构建。你将直接与产品和面向客户的团队合作，将定义不明确的问题转化为已上线的功能，并在优先级变化时快速调整范围。你将负责实现方式，这意味着要对薄弱的方案提出质疑，并在必要时做出决策。

Portcast is a venture-backed, Singapore-based logistics technology startup helping freight forwarders turn data into better decisions and measurable business impact.
Portcast uses AI to surface shipment exceptions, cost risks, and the right actions, helping teams focus on the shipments that need their attention, keep freight costs under control, and make procurement decisions with confidence. Our vision is to be the AI data and intelligence layer that powers exception management and margin improvement on every shipment.
Founded in 2018 and backed by leading technology investors, we are building for an industry at a critical inflection point of digital transformation. Our team of software engineers, data scientists, and logistics experts is on a mission to build the technology that helps freight forwarders protect margin, improve operational efficiency, and differentiate their offering.
ABOUT THE ROLE:
We're looking for a Senior Machine Learning Engineer who owns solutions end to end, from framing the problem, to building and deploying the model, to running it in production. This is a hands-on, business-minded role in a lean team: you'll build ML and AI that drives real outcomes for our customers, and make pragmatic calls about cost, scale, and impact, not just model accuracy.
Our models (like predictive ETA) are one part of the picture, not the whole job. You'll own some products end to end and contribute to others, and you'll help decide what's worth building based on what moves the business. You'll work closely with our Data, Engineering, and Product teams, turning loosely defined problems, sometimes without clean baseline data, into shipped features. If you like figuring things out in ambiguity and seeing your work drive the business directly, rather than long research cycles in a big lab, you'll fit well here.
What You’ll Own:
- Own ML and AI solutions end to end: frame the problem, build the model, deploy it, and run it in production (MLOps). You own the full lifecycle, not just the modelling.
- Own some products end to end and contribute to others, thinking about business outcomes, cost, and scale, and model performance.
- Comfortable building from a rough outline rather than a finished spec. You'll work directly with product and customer-facing teams to turn loosely defined problems into shipped features, and re-scope quickly when priorities shift. You'll own the how, which means pushing back on a weak brief and making the call when the spec runs out. We have a strong sense of direction; the details pivot often.
- Collaborate with Data, Engineering, and Product to understand the business goals behind what you are building, so what you ship actually moves the metrics that matter.
- Build, test, deploy, and monitor real-time prediction models and ML algorithms that address the key business problems our product focuses on: visibility, prediction, demand forecasting, freight audit, using MLOps best practices with version control and performance tracking.
- Productionise LLM-based systems where relevant, treating prompts and model behaviour as engineering artifacts.
- Perform feature engineering, model tuning, and validation so models are production-ready and optimized for performance.
WHAT WE'RE LOOKING FOR:
- Bachelor's, Master's, or PhD in Computer Science, Engineering, or a related field.
- 5+ years building, deploying, and scaling machine learning models in production, with a track record of owning things end to end.
- A business and software mindset over pure research. You think about business outcomes, cost, and impact, and you know when "good enough and shipped" beats a perfect model. Backgrounds that fit well include software engineers who moved into AI/ML, or ML engineers used to owning products end to end in a lean team.
- Prior experience in a lean product-based startup environment: a small ML/DS team where everyone wears many hats, with no big R&D lab and no clean specs or baseline data handed to you. You create clarity and make progress without every answer upfront.
- Experience in logistics tech or supply chain tech, ideally building AI-powered intelligence for freight forwarding, is a strong plus.
- Experience with real-time data processing, anomaly detection, and time-series forecasting in production.
- Experience with large datasets and big data technologies like Spark and Kafka.
- Strong Python and SQL, with experience in cloud platforms (AWS) and containerization (Docker, Kubernetes).
- Proven experience owning the full lifecycle, from R&D to production and MLOps, in fast-paced environments. You can build a model and run it in production yourself.
- Hands-on experience productionising LLM-based systems. Bonus points for designing AI agents and multi-step workflows, tool/function calling, and grounding models on proprietary data through retrieval and context design, and treating prompts and model behaviour as engineering artifacts: versioning, evaluation harnesses, guardrails, and monitoring output quality, latency and cost in live systems.
- First-principles thinking, a self-starter mentality, and the ability to take ownership end to end and work autonomously.
- Excellent communication, with the ability to convey complex technical concepts clearly, and a strong customer-obsessed mindset. You are genuinely curious about our industry, our customers, and the logistics domain, and you let that shape what you build.
What's In It For You:
- Own a high-leverage problem: your work drives real product and business outcomes, not research for its own sake.
- Real ownership from day one: we're 30 people and the data science team is small, so there are no layers, nowhere to hide and everywhere to make a mark. You own ML systems end to end and grow fast.
- Tech-first team: you'll work with people who care about solving hard problems with technology, and get exposure to complex product problems across software, data, ML, and logistics.
- Globally distributed, remote-first flexibility: work with a fully distributed team across Asia and Europe, built on trust, accountability, and collaboration.
Our CORE Values Guide Everything We Do:
- Curiosity: We stay close to the data and to model behaviour before we trust an output. We dig into why a model does what it does, not just whether the metric moved.
- Ownership: We act like founders. We take a model from research to production and stay on it, monitoring, debugging, and improving long after it ships.
- Raising the bar: We don't settle for a model that works in a notebook. We aim for systems that are reliable, scalable, and cost-aware in production.
- Effective: We focus on models that create real product and customer impact, not accuracy for its own sake.
