Job description

We are looking for an experienced Full Stack Developer with strong Python and Microsoft Azure expertise to join our engineering team building and scaling a PCI DSS v4.0-ready, microservices-based order processing platform. This platform running on a secure, private-network Azure architecture.

You will work across the full stack - from API design and serverless compute to database design and CI/CD - building secure, cost-efficient, and highly available services in a regulated, payment-adjacent environment.

What You'll Work On

• Design, build, and maintain Python-based microservices on Azure Functions (Python 3.11/3.12) across domains such as order intake, customer management, catalog, orchestration, tax, payment/PCI, fulfillment, notifications, and support APIs.
• Build and secure APIs exposed through Azure API Management (APIM) - including authentication, throttling, CORS, brand-scoped RBAC, and correlation-ID based tracing.
• Work within a Private VNet architecture, integrating Function Apps, Private Endpoints, NSGs, and NAT Gateway-based outbound connectivity to third-party partners (payment gateways, tax providers, OMS, email/mail services).
• Design and maintain schemas in a shared Azure SQL Database using module-owned table prefixes, optimizing for cost and performance at moderate transaction volume.
• Implement secrets and credential management via Azure Key Vault using Managed Identity - ensuring no hardcoded credentials anywhere in the platform.
• Build tokenized payment integrations (e.g., CyberSource/PayPal) ensuring PAN/CVV data never touches application code or storage - token-only handling.
• Contribute to PCI DSS v4.0 compliance controls: network segmentation, encryption in transit/at rest, access logging, audit trails, and secure system design.
• Support queue- and timer-triggered async processing (cron/orchestration patterns) for order lifecycle management with retry logic.
• Collaborate on cost-optimization decisions - right-sizing Function plans (Elastic Premium), SQL tiers, and reserved capacity planning.
• Monitor and troubleshoot production systems using Application Insights, Log Analytics, and Microsoft Defender for Cloud.
• Partner with stakeholders to translate deployment architecture and solution design into working, well-tested code.

Requirements

What We're Looking For

Required:

• 6-9 years of professional software development experience, with strong full-stack capability.
• Deep hands-on experience with Python (3.x) for backend/microservice development.
• Solid experience building and deploying on Microsoft Azure, specifically:
• Azure Functions (serverless compute, VNet integration)
• Experience designing RESTful APIs and microservices architectures.
• Experience with relational database design (schema design, query optimization, TDE/encryption-at-rest concepts).
• Understanding of secure application design: secrets management, least-privilege access, RBAC, TLS/encryption in transit.
• Familiarity with asynchronous/queue-based or timer-based processing patterns.
• Experience integrating with third-party APIs (payment gateways, tax engines, OMS, email/notification providers, etc.).
• Working knowledge of monitoring/observability tools (Application Insights, Log Analytics or equivalent).
• Strong understanding of CI/CD pipelines and cloud deployment practices.

Preferred / Nice to Have:

• Experience working in a PCI DSS-regulated environment.
• Exposure to e-commerce order management systems (Shopify, OMS platforms, or similar).
• Experience with tokenized payment processing (CyberSource, PayPal, Stripe, or similar gateways).
• Familiarity with Infrastructure as Code (Bicep, ARM templates, or Terraform on Azure).
• Front-end development experience (React/Angular/Vue) for full-stack contributions beyond APIs.
• Experience with cost optimization on cloud platforms (reserved capacity, right-sizing).
• Azure certifications (e.g., AZ-204, AZ-400, AZ-305) are a plus.

Soft Skills

• Strong ownership mindset - comfortable working across the stack from database to API to deployment.
• Ability to work in a security- and compliance-conscious environment with attention to detail.
• Clear communicator, able to work with architects and cross-functional stakeholders.
• Comfortable in a fast-paced environment balancing scalability, security, and cost.
