About MoonPay 🌖💸

Hi, we’re MoonPay. We’re here to onboard the world to Web3.

Why? Because we think Web3 is a unique and democratizing technology. It gives people back control of their money, digital identity, data, and property like nothing else before it.

What we do

We’re the leading infrastructure company in Web3. This means we offer our partners everything from payment solutions (we call them 'Ramps') to minting software for digital collectibles, like NFTs. And over 20 million people around the world now trust our products — just take a look on Trustpilot.

We’re also big on collaborations. And we've worked on stunts, drops, and partnerships with some of the world's most prestigious and forward-thinking brands.

But that’s not all. We have also built our own consumer app because we wanted to see if we could build a better Web3 account. It’s taken off in a big way, and we're working hard to continually improve it and to strive for perfection.

So whatever your background, we’re sure there’s something for you here. Come help us build the future of Web3 and digital ownership.

This role will be hybrid, and will require you to spend some portion of your time in our office in one of these locations.

About the Opportunity ✍️

We’re looking for a seasoned Machine Learning Engineer who understands the full life cycle of training machine learning models and putting them into production. This person can help us build, expand, and maintain our machine learning infrastructure and ecosystem.

In this role, you’ll be a part of the Data team. You’ll help implement machine learning systems that have significant impact on critical functions of the business. In your work, you’ll collaborate closely with MoonPay’s data scientists and operate cross-functionally with Engineering, Ops, Product, Fraud Prevention, and more.

As an MLOps Engineer, we’ll be looking to you to assess MoonPay’s current ML design, come up with a strategy to effectively expand and improve on ML implementations, and play a key role in ensuring that our ML systems continue to operate effectively.

What you will do…

  • Consult with data scientists on training machine learning models (after all, in a production environment, there are implications to model choices that need to be considered)

  • Provide a strategic vision on how to make machine learning a cornerstone to MoonPay’s business

  • Support additions and improvements to the ML infrastructure, including getting your hands dirty with data engineering and DevOps engineering

  • Design systems to meet throughput and latency requirements

  • Implement NFRs (Non-Functional Requirements) to ensure a high degree of system reliability

  • Implement and participate in practices (such as an on-call rotation) to ensure the continuous delivery of machine learning services

About You 🙋

You’ve been involved in MLOps before. In the past, you’ve worked closely with data scientists to help them bring experimental features and models to production. You know your way around implementing machine learning systems in a safe and reliable manner, you’re familiar with cloud infrastructure, you have experience with getting complex systems set up in a stable manner,, and you’re aware of potential pitfalls in machine learning systems that should be navigated around.

Now, you’re up for a challenge and are interested in having a significant impact on the success of MoonPay. You’re looking for an opportunity to stretch your MLOps capabilities to help a vibrant business scale up and scale out its machine learning capabilities.

Most importantly, though, you will embody the core principles that everyone here at the MoonPay lives by. Our “BLOCK Values” are at the heart of everything we do - and they are…

B - Be Humble

L - Lead with Empathy

O - Own It

C - Communicate with Clarity

K - Kaizen

What you will need…

  • Prior experience with productionising ML systems is a must.

  • Prior experience training machine learning models is highly desirable.

  • Advanced knowledge of Python and familiarity with SQL.

  • Good working knowledge of Terraform and Terragrunt for Infrastructure as Code (IaC)

  • A solid understanding and hands-on experience with real-time and event-driven systems such as Kafka, Kafkaconnect, Redpanda, Pub/Sub.

  • Solid experience with Kubernetes, docker, deployment types (canary, blue-green etc.)

  • Experience with setting up CI/CD systems using tools such as CircleCI, drone, Github actions, ArgoCD.

  • Working experience with Big Data technologies such as Spark, Dataflow, and Flink.

  • Experience with system design - keeping performance and efficiency in mind, whilst aware of trade-offs.

  • Experience applying software engineering rigor to ML, including CI/CD/CT, unit-testing, automation etc.

  • Hands-on experience with some MLOps tools such as KubeFlow, DVC, MLFlow.

  • Experience with cloud providers, such as GCP, AWS, or Azure (we are a GCP house)

  • Prior experience or a strong interest in FinTech, crypto, or web3 preferred.

Research has shown that women are less likely than men to apply for this role if they do not have experience in 100% of these areas. Please know that this list is indicative, and that we would still love to hear from you even if you feel that you are only a 75% match. Skills can be learnt, diversity cannot.
