The Role

We are seeking a Senior Software Engineer to build DailyPay's ML platform from the ground up. You will design and build the infrastructure that every machine learning model at DailyPay runs on: feature engineering platform, model training and deployment, serving infrastructure, and the monitoring that keeps it all reliable in production.

This is a software engineering role, primarily working in Python, Scala, Go, and managing infra as code with Terraform. You will build the platform that data scientists use to ship models, not build the models themselves. You own the infrastructure that makes their work reproducible, testable, observable, and production-safe at scale.

You will work closely with data scientists, engineers, and product stakeholders to deliver high-quality ML solutions that directly impact DailyPay's core products. You are expected to operate with significant autonomy: defining work, identifying dependencies, and raising the bar for the team around you.

How You Will Make an Impact

Platform Ownership: Help architect, design, and build DailyPay's unified ML platform from the ground up. Our ML Platform is a new unified system for model development, deployment, and monitoring that serves as the backbone for every AI and ML capability at the company.

Systems Design & Delivery: Design and build scalable, reliable services and pipelines covering feature generation, model training, deployment, and inference. Own end-to-end delivery with minimal oversight.

Self-Service Infrastructure: Build the tooling and guardrails that let data scientists define, test, and ship features and models independently, without needing an engineer in the loop and without bypassing validation, lineage, or rollback safeguards.

Cloud Infrastructure: Manage and optimize AWS infrastructure for machine learning workloads, balancing cost-effectiveness, security, and availability. Experience in AWS SageMaker or GCP Vertex is ideal.

CI/CD Pipeline Development: Build and maintain robust CI/CD pipelines for continuous integration and deployment of ML models and related infrastructure.

Monitoring & Observability: Design monitoring and alerting systems for ML infrastructure and models using tools like Datadog. Proactively identify and resolve issues before they impact production.

Technical Leadership: Lead design discussions, contribute to architectural decisions, and establish team norms for how ML systems are built, tested, and maintained. Help identify and remove blockers.

Mentorship: Mentor junior engineers. Share domain knowledge and help build genuine technical depth on the team.

Security & Compliance: Approach all engineering work with a security lens. Actively look for vulnerabilities in code and during peer reviews. Ensure ML pipelines handle sensitive data in accordance with company policy.

What You Bring to the Team

5+ years of professional software engineering experience building and operating production services

Strong background in distributed systems, service-oriented architecture, and API design

Experience across the full software lifecycle: design, testing, deployment, and on-call operations

Proficiency in Python, with a track record of writing production-quality, tested, maintainable code

Familiarity with ML frameworks (scikit-learn, XGBoost, PyTorch) and how they are used by AI and Data Scientists.

Experience with event streaming platforms (Apache Kafka or equivalent).

Experience with infrastructure-as-code (Terraform or CloudFormation), including module design and environment separation

Solid CI/CD experience: GitHub Actions or equivalent; designing and operating deployment pipelines

Experience with containerization and orchestration (Docker, and Kubernetes or ECS)

Experience building or operating ML infrastructure: training pipelines, model serving, feature stores, or model registries

Strong cloud platform proficiency: AWS preferred (SageMaker, Lambda, S3, EC2, IAM, ECS), or equivalent GCP (Vertex AI, Cloud Functions, GCS, Compute Engine, Cloud Run) or Azure (Azure ML, Functions, Blob Storage, VMs, AKS) experience

Experience with monitoring and observability tooling (Datadog, Prometheus, or Grafana)

Strong SQL skills and experience with data pipeline tooling (dbt, Glue, Snowflake)

Excellent communication skills; comfortable working across data science, engineering, and product teams

Nice to Haves

Experience with experimentation infrastructure and A/B testing systems

Experience in fintech or other regulated industries

Contributions to open-source infrastructure, platform, or MLOps projects
