About the Role

The Senior Platform Engineer will be responsible for designing, building, and maintaining Float’s cloud infrastructure and developer platform to ensure high performance, scalability, and security. This role sits at the intersection of platform engineering, DevOps, and software development, with a strong emphasis on automation, reliability, and developer productivity.

In addition to deep cloud and operational expertise, we’re looking for someone with strong development experience who can design and implement services, frameworks, and tooling that accelerate our engineering organization and drive adoption of our event-driven architecture.

What You'll Be Responsible For

Cloud Infrastructure & Operations

• Build and maintain a robust and efficient infrastructure by designing, deploying, and managing services such as ECS, EKS, and RDS.

• Optimize performance, availability, and reliability through monitoring, tuning, and continuous improvements.

• Ensure compliance with cloud security best practices by implementing and enforcing security measures across AWS environments and containerized applications.

• Maintain adherence to AWS Well-Architected Framework best practices.

Developer Platform & Experience

• Design and develop a world-class Internal Developer Platform (IDP) that empowers engineers with self-service infrastructure, standardized workflows, and automated guardrails.

• Enhance and maintain CI/CD pipelines to improve developer productivity, deployment speed, and system stability.

• Drive adoption of platform tooling and practices through documentation, advocacy, and direct collaboration with engineering teams.

Development & Architecture

• Contribute to the design and implementation of core platform services, frameworks, and libraries that underpin Float’s event-driven architecture.

• Collaborate with engineering teams to integrate platform and security best practices directly into development workflows.

• Participate in application architecture reviews, providing input on scalability, resilience, and security.

• Write clean, maintainable, and testable code in languages such as Go, Python, or TypeScript.

Security & Compliance

• Identify and mitigate risks through security assessments, vulnerability scans, and threat modeling.

• Develop and maintain security policies, procedures, and incident response plans tailored to cloud and container environments.

• Support compliance with standards such such as PCI-DSS 4.0 and SOC2.

Culture & Continuous Improvement

• Contribute to a culture of excellence by promoting automation, observability, and continuous improvement across the organization.

• Stay current with industry trends, emerging technologies, and best practices in AWS cloud, developer tooling, and event-driven systems.
