Senior Software Architect (.NET

Ops Guru, a Carbon
60 Company

Ops Guru 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.

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.

• 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 (No
  
  SQL) paradigms to transition applications from traditional RDBMS (SQL Server, MySQL, Oracle) to modern, fit‑for‑purpose targets (Postgre
  
  SQL, Dynamo
  
  DB, Mongo
  
  DB, Redis, etc.) where appropriate.

• 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.

• 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 & Road mapping:
  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.

• 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, Postgre
  
  SQL, Oracle) and proficiency with at least one No
  
  SQL platform (Cosmos
  
  DB, Dynamo
  
  DB, Mongo
  
  DB, Redis).
• AI & Developer Productivity:
  Proficiency using AI‑assisted development tools (Cursor, Claude Code, Git Hub 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.

• 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,…
