Full Stack Engineer - Platform Apps & Developer Experience

Role title: Full Stack Engineer Platform Applications & Developer Experience
Seniority: Senior Full Stack Engineer (hands-on build + operations, automation-first)
Platform: ChocoMake” (internal codename) — governed data mesh platform on Microsoft Fabric with Azure services, platform apps, and IaC automation

1) Context & Mission

ChocoMake is Barry Callebaut’s enterprise data platform, designed to scale analytics, BI, and AI through a governed data mesh. It provisions standardized data product zones (Dev/Test/Prod) for decentralized Data Product Teams and provides shared services, guardrails, automation, monitoring, and a self-service experience through a Global Management Zone. A critical part of this platform is the platform application layer: the portal, documentation site, and supporting APIs/automation that expose platform inventory, onboarding information, environment visibility, and cost transparency. As a Full Stack Engineer, your mission is to build and operate ChocoMake’s platform-facing applications so that platform usage is intuitive, self-service, secure-by-default, and observable.

You’ll work closely with Platform Engineers (IaC/blueprints) and Cloud Engineers (operations/SRE-style) to ensure that platform apps are:

• Secure (identity, least privilege, private networking)
• Reliable (monitoring, incident readiness)
• Automated (CI/CD, IaC-aligned deployment)
• Aligned with platform reality (pulling inventory from Terraform state and Azure resources)

2) What You Will Build & Operate (Core App/UX Scope)

You will support both global shared components and per-platform application components, aligned to the platform’s architectural patterns.

A. ChocoMake Portal (Core Internal Product)

• Full stack development for the ChocoMake Portal, including:
• Frontend UX for platform self-service views and inventory
• Backend APIs supporting portal features
• Data layer design and performance tuning
• Integration pattern: Terraform-state extraction SQL inventory portal views (platform inventory derived from IaC outputs/state).
• Runtime hosting:
• Azure App Service (including containerized deployment patterns)
• Azure SQL Database for portal persistence/inventory views
• Azure Container Registry for application images

B. Documentation Site (Docs-as-Code)

• Build and operate the platform documentation site using:
• MkDocs (docs-as-code)
• Azure Static Web Apps hosting
• CI/CD pipelines that publish documentation reliably and securely

C. APIs, Sidecars, and Automation Services

• Build services/sidecars that:
• Extract or interpret platform metadata (e.g., Terraform outputs/state, environment definitions)
• Populate portal SQL tables and platform inventory views
• Support self-service onboarding workflows and platform status visibility

D. Observability & Cost Transparency Surfaces

• Contribute to “ChocoMake Insights” type experiences by:
• Integrating cost exports / cost reporting outputs into portal views
• Surfacing health/status signals (alerts, dashboards summaries) in a product-friendly way

E. Security & Networking Constraints You Must Respect

• Platforms patterns include:
• Private endpoints, private DNS zones, and disabling public network access via IaC/variables
• Key Vault with private endpoints and secret lifecycle
• Entra ID / RBAC group patterns and least privilege
• Your applications must function correctly in private networking contexts and support secure identity flows.

3) Key Responsibilities

A. Build Product-Grade Platform Applications

• Deliver high-quality frontend and backend features for the ChocoMake Portal.
• Design APIs and services with clean contracts and good performance.
• Implement robust data models and query patterns in Azure SQL DB to support inventory and reporting needs.

B. Operate What You Build (DevOps + SRE Discipline)

• Own production readiness for platform apps:
• Monitoring, alerting, logging, dashboards
• Incident response participation, RCA contributions, and remediation
• Maintain availability and reliability for platform apps across Dev/Test/Prod.

C. Automation-First Delivery (CI/CD)

• Maintain Azure DevOps pipelines for:
• Container build/push (ACR)
• App Service releases (including webhook/continuous deployment patterns where applicable)
• Static Web Apps publication for docs (MkDocs)
• Ensure versioned releases, rollback strategies, and safe config management.

D. Secure-by-Default Engineering

• Implement identity and access patterns aligned with platform standards:
• Entra ID groups and RBAC
• Managed identities where appropriate
• Secrets via Key Vault (never in code/pipelines)
• Ensure compliance with private endpoint/DNS patterns (no “works only on public internet” shortcuts).

E. Platform Alignment and Cross-Team Enablement

• Work with Platform Engineers to ensure the portal reflects the actual IaC truth (inventories, environments, standards).
• Work with Cloud Engineers to align operational monitoring, alerts, and incident handling.
• Create documentation and developer guidance to reduce support load and accelerate adoption.

4) Must-Have Technical Skills (Selection Criteria)

Full Stack Engineering (Senior Level)

• Strong experience delivering modern web applications end-to-end:
• Frontend: React/TypeScript (or equivalent enterprise-grade SPA stack)
• Backend: Node.js/.NET/Java (any is acceptable if you demonstrate strong API engineering)
• API design discipline (REST, auth, pagination, error models, idempotency).

Azure Application Hosting & Cloud Operations

• Hands-on experience with:
• Azure App Service (including containerized deployments)
• Azure Container Registry
• Azure Static Web Apps
• Azure SQL Database
• Comfortable troubleshooting real production issues (latency, connectivity, auth, DNS/private endpoints).

DevOps & Automation

• Azure DevOps pipelines (build/release), Git workflows, PR reviews.
• Container build and deployment pipelines.
• Comfort working in IaC-driven environments (understanding Terraform outputs/state usage even if not a primary Terraform author).

Security Foundations

• Entra ID concepts (app registrations/service principals), RBAC, managed identities.
• Secure secrets management with Key Vault.
• Strong awareness of private networking implications (private endpoints, private DNS).

Observability

• Azure Monitor + Log Analytics fundamentals, structured logging, alert tuning.

5) Strong Advantages (Nice-to-Have)

• Experience building internal developer platforms or self-service portals that integrate with IaC inventories.
• Familiarity with data platform concepts (Fabric workspaces/capacities, OneLake, ADF) to better present platform status and inventory.
• Experience in cost transparency UX (tagging, cost exports, chargeback views).
• Experience building secure apps in “no public endpoint” enterprise environments.

6) Ways of Working & Expectations

• You work in an engineering-first, automation-first culture: PR-based changes, repeatable deployments, clear ownership.
• You care about operability as much as features: if it can’t be monitored and supported, it’s not done.
• You collaborate effectively across platform engineering, cloud operations, and data product teams to keep the platform experience coherent and trustworthy.

7) Deliverables You’ll Be Accountable For (First 6–12 Months)

• Improved ChocoMake Portal capabilities (inventory accuracy, onboarding UX, platform insights).
• Stable CI/CD pipelines for portal, APIs, and docs-as-code.
• Hardened security posture for platform apps (Key Vault, MI, RBAC alignment, private networking).
• Improved observability: dashboards, alerts, and runbooks that reduce MTTR for platform-app incidents.

8) Interview Focus Areas (How We Will Assess Fit)

• System design: design a portal feature that reads platform inventory from IaC outputs/state and serves it reliably.
• Azure operations scenario: diagnose a production issue involving private endpoints/private DNS and App Service connectivity.
• CI/CD: propose a pipeline approach for container build/push + App Service release + rollback.
• Security: identity model choice (service principal vs managed identity), Key Vault integration, least privilege.
• Quality: testing strategy, API error contracts, performance approach for Azure SQL queries.
