Senior Software Engineer

Your profile At Cenosco, we build Asset Integrity Management Software trusted by global leaders in Oil & Gas, Chemicals, and Energy.  As we invest heavily in AI-powered product capabilities, we need Senior Software Engineers who are as excited about building intelligent features as they are about clean, scalable code .

You will design and ship backend-heavy features on a modern SaaS platform, contribute to AI-powered product experiences, and bring a mindset that embraces AI-assisted development as part of how great engineers work today. What You'll Do

Product Engineering

• Design, build, and ship high-quality features across the  Cenosco  platform, contributing to the full development lifecycle from architecture to production
• Write clean, maintainable, well-tested code in C# / .NET
• Contribute to system architecture and design discussions , influencing how we build scalable and maintainable solutions
• Collaborate closely with Product and Design to translate business requirements into solid technical implementations
• Participate in code reviews, raise the quality bar, and share knowledge across the engineering team

AI-Powered Features

• Build and integrate AI-powered product capabilities   -  from LLM integrations and intelligent workflows to data-driven features that add real value for customers in industrial environments
• Work alongside  whole  Engineering team   to bring models and AI services into the product in a way that is robust, observable, and production-ready
• Contribute to the team's thinking on where AI can meaningfully improve the product experience for our users

AI-Augmented Development

• Use AI coding tools  (such as  GitHub Copilot, Cursor, Claude Code, or Codex ) as a natural part of your development workflow to move faster, explore solutions, and maintain high output quality
• Bring a pragmatic, curious approach to adopting new tooling and practices as the AI development landscape evolves
• Share what works with the team and help establish good habits around AI-assisted engineering

What You'll Need

• 7 + years of professional software engineering experience in a SaaS or enterprise product environment
• Strong backend engineering background ,  professional C# / .NET experience
• Solid grasp of software design principles:  clean code, SOLID, architectural patterns, and API design
• Experience with relational databases and working knowledge of cloud infrastructure ( Azur e,  AWS  or GCP )
• Familiarity with modern engineering practices:  CI/CD, Docker, Kubernetes, code review culture
• You've meaningfully integrated AI coding tools into your workflow and can speak to how  they've  changed the way you architect, debug, or ship code.
• You think natively in terms of what AI can unlock for users - you've shipped product features powered by LLMs, embeddings, agents, or similar, and you understand the tradeoffs (latency, cost, reliability, hallucination) that come with them.
• You treat AI as a core part of how you work and build - you use it daily in your dev workflow,  you've  shipped real AI-powered features
• Strong communication skills and a collaborative, proactive approach to problem-solving

Bonus Points For

• Experience building or integrating LLM-based features (prompt engineering, RAG patterns, API integrations with OpenAI, Azure OpenAI, or similar)
• Knowledge of Oil & Gas, industrial, or asset-intensive domain
• Experience with full-stack development, including React or similar frontend frameworks
• Background in SaaS platforms with multi-tenant architecture
• Exposure to complex data models or domain-driven design
