About The Position

We are seeking a Senior Software Architect with deep .NET expertise to work alongside engineering teams, helping implement architectural patterns and standards defined by our Enterprise Architect and Software Architects. This role focuses on execution, translating architectural decisions across our core .NET application stack into working software. This is a highly hands-on role. You’ll spend significant time in the codebase, implementing patterns, reviewing code, pairing with developers, and ensuring that day-to-day technical decisions (including distributed systems and integration design) align with our architectural standards. You’re not just advising; you’re building. You’ll work with teams on specific initiatives or problem areas, helping implement a new integration pattern, supporting a modernization effort, standing up an LLM-powered capability. Your impact is direct and tangible.

Requirements

8+ years of progressive experience in software engineering, with demonstrated technical leadership or senior developer experience
3+ years of making technical and architectural decisions for your team
Strong hands-on coding skills, you’re an experienced developer who writes production code regularly
Deep, hands-on expertise in .NET/C# and React our core application language — you’re comfortable architecting across the full stack, not just a single service or layer.
Working familiarity with distributed systems and messaging frameworks (e.g., pub/sub, message queues, event-driven communication)
Familiarity with cloud platforms, particularly Azure or AWS
Understanding of modern application architectures: microservices, API design, event-driven patterns
Ability to work across different teams and adapt to varying codebases and contexts
Strong communication skills, you can explain technical concepts clearly to other developers
Curiosity about the “big picture,” you want to understand how systems fit together, not just your piece
Working familiarity with Python
Bachelor’s degree in Computer Science, Information Systems, or related field

Nice To Haves

Experience with the broader tech stack: React, Python, Snowflake, dbt
Hands-on experience building with large language models (LLMs) in production or near-production settings
Practical experience with prompt engineering, including designing, testing, and iterating on prompts for reliability and consistency
Experience with LLM observability or evaluation tooling such as Langfuse (or comparable platforms)
Familiarity with retrieval-augmented generation (RAG), vector databases, or agentic workflow patterns
Familiarity with our toolchain: TeamCity, Octopus Deploy, Azure DevOps, GitHub Actions
Exposure to integration patterns: REST APIs, message queues, CDC
Experience with database design and data modeling concepts
Background in DevOps practices and CI/CD pipelines
Experience working in multi-tenant SaaS environments
Prior experience in B2B SaaS or enterprise software development

Responsibilities

Implement architectural patterns and standards defined by the Enterprise Architect and Senior Software Architects, including distributed systems and messaging patterns across our .NET services
Work within engineering teams to ensure solutions, across our .NET application stack align with established architecture decisions
Identify implementation challenges early and escalate to the team when decisions need to be revisited
Validate that completed implementations meet architectural requirements through hands-on review
Design and implement patterns for integrating LLMs into product features, including prompt design, context management, and retrieval-augmented approaches
Apply prompt engineering techniques to build reliable, maintainable AI-driven features, and iterate on prompts based on observed model behavior
Use LLM observability tooling such as Langfuse to trace, evaluate, and debug AI workflows in development and production
Help define and apply evaluation approaches for AI features, covering accuracy, latency, cost, and safety considerations
Write code regularly, this role requires significant time in the codebase implementing patterns and working alongside developers
Conduct detailed code reviews focused on architectural alignment, code quality, and maintainability
Pair with developers to work through complex implementation challenges, including those involving distributed systems, messaging, or, occasionally, LLM integrations
Help teams evaluate, and implement document chunking and embedding strategies to optimize for their customer’s use cases
Prototype approaches to validate architectural decisions before broader rollout
Embed with engineering teams on focused assignments based on architectural priorities
Build strong working relationships with developers and engineering leads
Participate in technical discussions, bringing architectural perspective to implementation decisions
Help teams understand the “why” behind architectural standards, not just the “what”
Surface patterns and challenges observed in teams back to Solution Architects and Enterprise Architect
Seek feedback on architectural thinking and implementation approaches
Study our existing architecture, understanding the rationale behind current patterns and the history of key decisions
Develop broader perspective across the platform by working with multiple teams over time
Document implementation patterns and approaches that teams can follow, including AI implementation patterns
Contribute to architecture decision records (ADRs) by capturing implementation learnings
Communicate clearly with developers about architectural expectations and rationale
Raise questions and surface ambiguities in architectural guidance to improve clarity for all teams
