The Mission & Your Impact :

  • Today, we build and operate critical systems in the anti-fraud, compliance, marketing, pricing and customer care domains.
  • Your mission is to guide us through our next chapter : building a robust Platform that other engineering and data science teams will use to ship their own features.
  • You won't just be writing services; you'll be architecting the foundational systems that enable faster, safer innovation across the company.
  • True Impact : You will have a direct hand in building a platform from the ground up. Your work will enable secure financial access for families across the globe.

What You'll Build & Own :

  • Platform Core : Design, build, and optimize high-performance Golang microservices that will serve as the backbone for our new platform.
  • ML Infrastructure : Automate and enhance our MLOps pipeline using MLflow.
  • Tackle challenges like dynamic model selection, champion-challenger patterns, and shadow mode deployments to make our systems more agile and intelligent.
  • Dynamic Workflow Engine : Integrate ML models and business rules directly into our customer verification workflows, moving beyond static configurations to a dynamic, rules-driven system.
  • Data & Feature Engineering : Develop scalable ETL pipelines and feature stores to power real-time model inference and complex aggregations for compliance monitoring.
  • Cloud-Native Foundation : Own and evolve our infrastructure on AWS (EKS, Kafka, SQS, OpenSearch, etc.), with a strong focus on observability (Prometheus, Grafana, Splunk), reliability, and incident response.
  • We're Looking For :

  • A proven track record (4+ years) of designing, building, and shipping production-grade systems in Golang.
  • Deep experience with cloud-native architectures on AWS (or similar), including container orchestration (Kubernetes / EKS) and managed services (Kafka, SQS).
  • Strong engineering fundamentals : distributed systems, databases (SQL / NoSQL), and API design.
  • A passion for solving complex business problems with elegant technical solutions.
  • You see the "big picture" without losing sight of the critical details.
  • Excellent communication skills (English B1+) and the ability to guide technical strategy and mentor peers.
  • It Would Be a Major Plus If You Have :

  • Experience building internal platforms or developer tools for other engineering teams.
  • Knowledge of ML systems lifecycle (training, serving, monitoring) and tools like MLflow.
  • Familiarity with workflow engines (e.g., Camunda, Temporal) or rule engines (e.g., Grule, Drools).
  • Background in the FinTech, marketing, anti-fraud, or compliance domains.
  • Hands-on experience with infrastructure-as-code (CDK, Terraform) and a keen sense for operational excellence.
  • What We Offer :

  • Remote work flexibility – work from anywhere.
  • B2B contract with competitive gross compensation in USD.
  • Top-tier hardware to support your productivity.
  • A challenging role in a team of skilled professionals.
  • Continuous learning and career growth opportunities.
  • Coverage for professional development : training, seminars, and conferences.
  • Access to high-quality English lessons.
