Senior Software Architect (.NET)

OpsGuru, a Carbon60 Company

OpsGuru is a global engineering and consulting group that helps organizations accelerate digital transformation and modernization through cutting-edge technology, deep engineering expertise, and outcome-driven solutions.

About the Role

We are seeking a Senior Software Architect to join our professional services delivery team. In this role, you will bridge the gap between complex business requirements and technical implementation.

You will act as a trusted advisor to our clients, leading the design and delivery of diverse solutions ranging from greenfield development to the migration of legacy systems into modern, cloud-native architectures. While your core focus will be the Microsoft stack (.NET), as a consultant, you must possess the technical versatility to adapt to diverse client environments and mixed-technology ecosystems.

Key Responsibilities

Architecture & Design Strategy

• Lead the architectural vision for complex software systems, ensuring designs are scalable, resilient, and aligned with business goals.
• Design and advocate for modern architectural patterns, specifically Domain-Driven Design (DDD), CQRS, Event-Sourcing, and Event-Driven Architecture.
• Evaluate and select appropriate data stores, utilizing both relational (SQL) and non-relational (NoSQL) paradigms to transition applications from traditional RDBMS (SQL Server, MySQL, Oracle) to modern, fit-for-purpose targets (PostgreSQL, DynamoDB, MongoDB, Redis, etc.) where appropriate.

Modernization & Migration

• Drive application modernization initiatives, taking ownership of migrating legacy .NET Framework (4.x) applications to modern .NET 8+ environments.
• Decompose monolithic applications into service-oriented or microservice-based architectures.
• Refactor and re-architect systems to leverage cloud-native services (Containers, Serverless/Functions) rather than simple "lift and shift" strategies.

Consulting & Technical Leadership

• Stakeholder Management: Act as the primary technical contact for clients, translating complex technical concepts, including ROI and cost-benefit analysis into clear business value for non-technical stakeholders.
• Well-Architected Solutions: Design and review systems against all core architectural pillars (Security, Reliability, Performance, Operational Excellence, and Cost Optimization) to ensure holistic quality.
• Discovery & Roadmapping: Lead discovery sessions to define technical backlogs, estimate effort, and identify risks early in the engagement.
• Team Leadership: Mentor senior engineers, enforce code quality standards, and conduct architectural reviews.

Requirements

Mandatory Technical Experience

• Core Expertise: Senior-level experience in C# and .NET. Extensive experience in both legacy (ASP.NET, .NET Framework 4.x) and modern .NET stack (ASP.NET Core, .NET 6/8+).
• Architecture Patterns: Deep, practical experience implementing Microservices, Domain-Driven Design (DDD), CQRS, and Event-Sourcing.
• Cloud Native: Strong experience designing for public cloud platforms (AWS, Azure, or GCP), including containerization (Kubernetes/AKS/EKS) and Serverless functions.
• Database Expertise: Extensive experience with Relational (SQL Server, PostgreSQL, Oracle) and proficiency with at least one NoSQL platform (CosmosDB, DynamoDB, MongoDB, Redis).
• AI & Developer Productivity: Proficiency using AI-assisted development tools (Cursor, Claude Code, GitHub Copilot) to accelerate code generation, refactoring, and testing
• Ecosystem Versatility: Demonstrated ability to quickly adapt to new languages and frameworks outside of the Microsoft ecosystem when client needs dictate. A "polyglot" mindset is essential.

Mandatory Consulting Skills

• Consulting DNA: Proven experience working in a professional services or consulting environment. You must be comfortable managing client expectations, navigating ambiguity, and delivering outcomes within scope and budget.
• Communication: Exceptional verbal, written, and presentation skills (English). You must be able to lead design discussions and defend architectural decisions to C-level executives and engineering teams alike.
• Delivery Focus: Ability to plan and lead large-scale projects, including critical cutover and rollback events.

Nice to Have

• Additional Language Proficiency: While C# is primary, experience with other stacks is highly valued:
  • Java: (Spring, Play, etc.)
  • NodeJS/TypeScript: (Express, NestJS, etc.)
  • Python: (Django, Flask, etc.)
• Big Data & Data Engineering: Exposure to large-scale data processing and storage ecosystems (Apache Spark, Databricks, Snowflake, Kafka, or Hadoop).
• Front-End Awareness: Understanding of modern SPA frameworks (React, Angular, Vue) to effectively design API contracts.
• Certifications: Solutions Architect certifications in Azure or AWS.

Benefits

Compensation & Perks

• Competitive compensation package (CAD 170K-200K / year)
• Retirement Savings Matching Program (RRSP)
• Partnership with Perkopolis Discounts

Flexibility & Time Off

• Remote first work environment
• Flexible work hours & location
• Paid parental leave options

Health & Wellness

• Employer-paid health & dental premiums
• GreenShield+ Counselling Mental Health
• $500 in Health Care Spending Account annually

Growth & Development

• Training reimbursement (e.g courses on Udemy, Coursera, a-cloud-guru etc.)
• Peer recognition rewards
