About the Role
We are looking for an experienced Full Stack Developerwith strong Python and Microsoft Azure expertise to join our engineeringteam building and scaling a PCI DSS v4.0–ready, microservices-based orderprocessing platform. This platform running on a secure, private-networkAzure architecture.
You will work across the full stack — from API design andserverless compute to database design and CI/CD — building secure,cost-efficient, and highly available services in a regulated, payment-adjacentenvironment.
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)
- Azure API Management
- Azure SQL Database
- Azure Key Vault & Managed Identity
- Azure VNet, NSGs, Private Endpoints, NAT Gateway
- 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.
