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.

 

Technical Skill Set

• Backend
  • Python (Flask), REST APIs
  • PostgreSQL / PostGIS (spatial data)
  • Database migrations (Flyway or equivalent)
  • Microservices and integration patterns

• Frontend
  • React, TypeScript
  • Vite, TanStack Router & Query
  • Zustand
  • D3.js (SVG, spatial visualization)

• Optimization
  • Python based optimization engines
  • NumPy, SciPy, Shapely
  • Constraint solving and geometry based logic

• Azure & DevOps
  • Azure App Service, Azure Functions, Static Web Apps
  • Application Insights, OpenTelemetry
  • Azure DevOps Pipelines
  • Bicep, PowerShell (IaC)
  • Git based workflows
