Join our team as a foundational senior engineer to help us evolve from a service-oriented squad into a platform team powering secure, global financial services and telecommunications offerings.

We are building the intelligent backbone that powers and protects millions in cross-border transactions, and your expertise will be critical in shaping its future.

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.
    • Technical Leadership: This is a senior role with high autonomy. We will rely on your skills to guide our architecture and technology choices.
    • A collaborative environment in a team of skilled, passionate professional

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.
