Senior Software Engineer, Cloud Platform

Signifyd is a company that helps merchants confidently grow their businesses by building trusted relationships with their customers. They are seeking a Senior Software Engineer for its Cloud Platform Engineering group to drive the design, implementation, and management of enterprise cloud infrastructure while providing technical leadership to a team of engineers.

Responsibilities:

• Pioneer AI-Driven Infrastructure
• Build the future: Architect and integrate LLM-powered, agentic tools into our platform ecosystem. You will design self-healing infrastructure and automated root-cause analysis workflows to drastically reduce operational toil and accelerate incident resolution
• Architect for Scale, Security, & Reliability
• Evolve the ecosystem: Drive the strategic roadmap for our GCP and Kubernetes-based cloud capabilities, balancing direct developer feedback with emerging cloud technologies
• Drive operational excellence: Define, build, and maintain rigorous system Service Level Objectives (SLOs) and incident management processes. You will share ownership of platform health by participating in on-call rotations, using those frontline insights to continuously harden our systems
• Embed security: Design transparent platform security (access controls, encryption, vulnerability management) that keeps the platform secure without slowing down developer velocity
• Optimize footprint: Manage cloud capacity and FinOps proactively, offering efficient scaling solutions and cost transparency to engineering teams
• Elevate Developer Experience (DevEx)
• Productize the platform: Transform CI/CD (GitHub Actions, TeamCity), deployment (ArgoCD), and build tooling into a cohesive, self-service product that drives Change Failure Rates (CFR) to zero
• Pave the golden path: Embed platform standards directly into our tooling so that the 'right way' is automatically the fastest and easiest way for our software engineers
• Technical Leadership & Mentorship
• Solve systemic problems: Provide high-level, solutions-oriented support by troubleshooting complex infrastructure issues and delivering resilient, product-level fixes
• Champion the culture: Foster a customer-focused engineering environment. You will mentor junior team members and advocate for product-thinking and deep empathy for the developer experience

Requirements:

• Deep proficiency in Google Cloud Platform (GCP) is required; AWS experience is a strong plus
• In-depth knowledge of cloud networking, protocols, and security best practices
• Extensive expertise operating both self-managed and cloud-managed Kubernetes architectures at scale
• Experience managing and scaling robust data storage and streaming technologies (e.g., PostgreSQL, MySQL, Cassandra, Elasticsearch, Kafka)
• Strong software development skills in high-level languages (e.g., Python, Go, Java, TypeScript) combined with modern development practices
• Proven ability to build secure, self-service infrastructure using Infrastructure-as-Code (Terraform) and declarative CI/CD pipelines (ArgoCD, GitHub Actions, TeamCity) to deploy with confidence and drive down CFR
• Proficiency using modern AI-assisted development tools (Cursor, GitHub Copilot, Claude)
• Architectural critical thinking required to audit AI-generated code for security, correctness, and long-term maintainability
• Experience designing scalable, OpenTelemetry-based monitoring and tracing frameworks that equip engineering teams to swiftly pinpoint bottlenecks and lower MTTR
