Employment Type: Full-Time Location Type: Remote Salary: $160,000 - $180,000 per annum + bonus/equity

🌐 Who We Are

Bankjoy is a Y Combinator and Bessemer Venture Partner backed FinTech startup. We are changing the way community banks and credit unions do business, enabling them to become tech-driven and digital first. Bankjoy provides modern digital banking products including mobile banking, online banking, online account opening, loan origination, and conversational AI. Our mission is to revolutionize banking tech infrastructure by leading digital transformation at financial institutions — big and small.

💼 The Role

Bankjoy is hiring a Principal Platform Engineer (Azure) to lead the evolution of our Microsoft Azure infrastructure. This role is ideal for someone who thrives at the intersection of DevOps, cloud security, and platform tooling development. We’ve built a strong cloud foundation using Kubernetes, IaC, and containerized microservices—now we need your help to scale it securely and efficiently.

You’ll focus on cloud architecture, security hardening, cost/performance optimization, and internal tooling development to empower engineers and defend against operational risks (e.g., bot attacks, misconfiguration, drift).

This is a hands-on role for a deeply technical individual contributor who also communicates well, documents decisions, and leads by example.

🧠 What You’ll Do

• Own the architecture and roadmap for Bankjoy’s Azure cloud infrastructure, with a focus on scalability, security, and developer efficiency.
• Design and build internal tools or services (e.g., bot detection, threat monitoring, configuration validators, internal dashboards), using C#/.NET Core or other languages.
• Harden our cloud security posture with proactive threat modeling, security scanning, IAM policies, encryption strategies, network segmentation, and regulatory compliance (e.g., S/DAST, SOC 2, PCI, OWASP).
• Maintain and evolve our IaC stack (Terraform, Bicep) to deliver secure, repeatable, and auditable infrastructure.
• Optimize infrastructure costs and performance across compute, storage, and networking layers.
• Manage Azure networking components like VNets, route tables, NSGs, and hybrid cloud interconnectivity.
• Lead infrastructure incident response, contributing to postmortems and mitigation strategies.
• Document infrastructure changes and architectural decisions to support internal knowledge-sharing and external audits.
• Support performance benchmarking and reliability testing for Kubernetes workloads and managed Azure services.
• Apply structured critical thinking to evaluate trade-offs, identify blind spots, and make informed decisions under uncertainty.
• Balance complex priorities across long-term infrastructure initiatives, real-time operational issues, and tactical internal requests.
• Communicate clearly and constructively across engineering and leadership—whether writing architectural diagrams, presenting security recommendations, or contributing to postmortems.
• Collaborate cross-functionally to ensure cloud infrastructure supports business goals, development velocity, and compliance outcomes.

🎯 What You Bring

• 10+ years in cloud/platform engineering, DevOps, or SRE roles, with 3+ years focused on Azure.
• Proven experience building internal tools and services using C#/.NET Core (or equivalent) to support platform use cases (e.g., observability, automation, security analysis).
• Hands-on expertise with Kubernetes, containerized workloads, and cloud-native patterns.
• Deep understanding of Azure security services: IAM, Key Vault, Defender for Cloud, encryption-in-transit/at-rest, and access control.
• Proficiency in Terraform, Bicep, or other declarative IaC tooling.
• Strong command of Azure networking concepts (VNets, firewalls, Private Endpoints, hybrid networking).
• Familiarity with observability tooling (Azure Monitor, Prometheus, Grafana, DataDog, or similar).
• Working hours must align with Central or Eastern Time Zones to ensure effective collaboration with our team.
