TECH S and T-FullStack Engineer-Senior

Full Stack Developer – Senior Consultant

(Python | Azure | PostgreSQL/PostGIS | React | Optimization Systems)

Role Summary

A Full Stack Senior Consultant is responsible for designing, developing, and supporting end to end solutions across frontend, backend, optimization engines, and Azure cloud infrastructure for the Drill & Blast System (DBS). The role requires strong technical depth, solution ownership, and the ability to translate complex domain requirements into scalable, production ready systems.

The Senior Consultant operates as a technical owner at feature or workstream level, mentor to consultants, and key contributor to architectural decisions.

Key Responsibilities

• Backend & API Development
• Design, develop, and maintain RESTful APIs using Python (Flask).
• Implement domain driven backend logic for:
• Blasts, drill/blast domains, pattern designs, charge rules
• Environmental controls, sensitive sites, simulations, optimization jobs
• Manage spatial data workflows using PostgreSQL with PostGIS.
• Write and optimize database queries, migrations, and schemas.
• Integrate backend services with external systems (e.g., Vulcan, Foundry, MAS, ArcGIS, IHMP).
• Ensure API security, reliability, and performance.

• Frontend Development
• Develop and enhance React (TypeScript) single page applications.
• Build performant and maintainable UI using:
• React 19, Vite, TanStack Router & Query, Zustand
• D3.js for spatial and geometry based visualization
• Integrate frontend components with backend APIs.
• Ensure usability, responsiveness, and correctness of spatial visualizations.
• Follow design system standards and UI best practices.

• Optimization & Algorithm Integration
• Integrate and support optimization engines (Python based) for blast pattern design.
• Work with optimization workflows involving:
• NumPy, SciPy, Shapely
• Kuz Ram fragmentation models
• Constraint based geometric solvers
• Coordinate execution of long running optimization jobs.
• Analyze and troubleshoot optimization failures and edge cases.

• Azure Cloud & Background Processing
• Build and manage services deployed on Azure App Service, Azure Functions, and Static Web Apps.
• Implement background jobs and schedulers (e.g., availability checks, geology hardness jobs).
• Configure Application Insights and OpenTelemetry for monitoring and diagnostics.
• Troubleshoot production issues using logs, telemetry, and metrics.
• Support environment specific deployments (dev, qa, uat, prod).

• Infrastructure & DevOps
• Contribute to IaC using Bicep and PowerShell.
• Work with Azure DevOps pipelines for CI/CD:
• Build, deploy, integration testing, security scanning
• Support automation scripts and operational pipelines.
• Ensure secure configuration of secrets, authentication, and environments.

• Quality, Testing & Governance
  • Write and maintain unit, integration, and end to end tests.
  • Support Postman collections and integration test suites.
  • Participate in code reviews and enforce engineering standards.
  • Ensure delivery meets performance, security, and maintainability expectations.

• Technical Leadership & Collaboration
  • Own delivery of assigned features or technical workstreams.
  • Mentor Consultants and support junior developers.
  • Participate in architecture and design discussions.
  • Collaborate with product owners, domain experts, QA, and operations teams.
  • Provide effort estimations and technical risk assessments.

• Problem Solving Skills
  • Ability to design and reason about complex distributed systems.
  • Strong debugging capability across frontend, backend, database, and cloud layers.
  • Analytical thinking for spatial data, optimization logic, and domain workflows.
  • Proactive identification of performance, scalability, and reliability risks.
  • Ability to resolve production issues under operational constraints.
