We are looking for a Machine Learning Engineer to help scale the industrialization of our ML lifecycle. This is a Builder’s Role - you will be responsible for the high-scale architecture that allows our models to survive production. You’ll be a key contributor to our MLOps ecosystem, moving beyond experimentation to build high-throughput, distributed systems that serve as the backbone of our intelligence products.
Machine Learning Engineers help us extract value from our data. They are involved in all the processes from data collection, cleaning, and preprocessing, to training models and deploying them to production. This position will assess, analyze, and organize data, execute tests, and optimize the learning process to develop high-performance machine learning models.

The Reality Check:
While the title says pure ML, the day-to-day is data heavy and is also focused on the AI and ML Platform Engineering around our services. Expect a roughly 90/10 split - the vast majority of your impact will come from hardening data pipelines, refining CI/CD for ML, and building world-class observability, with the remaining portion dedicated to model building, implementation and tuning.

About us:
We believe the next generation of financial services will be powered by stablecoins.
Founded in 2021, our mission at BVNK is to accelerate global money movement.
We’re building stablecoin-native infrastructure so businesses can move value instantly across borders and networks. With global licenses and T1 bank partnerships, we facilitate billions in transactions for enterprise clients like Worldpay, Deel, LianLian Global, and Rapyd.
Our technology is transforming how businesses operate globally by eliminating payment delays, reducing costs, and unlocking trapped capital.

In 2025, we secured strategic investment from Visa, following our $50 million Series B with Haun Ventures, Coinbase Ventures, Scribble Ventures, DRW Venture Capital, Avenir, and Tiger Global. With the backing of these leading investors, we’re accelerating our growth – and we're looking for smart, ambitious people to help us build the future of financial services.

About this role in the team:
We are looking for a QA Engineer who views AI as their primary leverage. At BVNK, we aren't just looking for someone to maintain scripts; we want an engineer who views manual, repetitive testing as a problem to be solved with intelligent agents.
You will join a team of Quality Assurance experts responsible for the end-to-end integrity of our Fiat and Crypto products. Your mission is to evolve our testing from "automated" to "autonomous." You will build intelligent testing systems that predict failures, self-heal scripts, and utilize LLMs to bridge the gap between complex financial requirements and bulletproof code.
