About Modular Solutions

Founded in 2015, Modular Solutions delivers enterprise-grade technology to the insurance industry. Our integrated platform enables insurers, mutuals, MGAs, and brokers to manage core operations through a single, highly configurable system. Designed for flexibility and long-term growth, our platform supports organizations operating in complex and regulated environments.

Position Summary

We are hiring several Software Developers across our product and platform teams. This posting spans intermediate to senior levels. Final level and team placement will be determined during the interview process based on demonstrated experience, strengths, and business needs.

AI is now a standard part of modern software development. At Modular Solutions, we expect engineers to be comfortable using generative AI tools as part of their daily workflow and to apply strong judgment when reviewing and validating outputs.

Some team members will focus on building production-grade AI-powered capabilities, including LLM integrations and retrieval-based workflows. Others will build core platform features that integrate with and extend these AI services. All developers are expected to collaborate across teams and contribute to high-quality, scalable systems.

Key Responsibilities

• Collaborate in an Agile Scrum environment, including sprint planning, reviews, and retrospectives.
• Work with cross-functional teams to deliver features that drive measurable business value.
• Participate in full SDLC activities, including research, estimation, proofs of concept, code reviews, deployments, and documentation.
• Write high-quality, performant, testable, and maintainable code.
• Maintain and develop robust backend systems and REST APIs using .NET Core and Entity Framework, with a strong emphasis on scalability, configurability, and clean service boundaries.
• Build responsive, user-friendly applications using React and TypeScript.
• Design and implement extensible integration patterns that enable seamless connectivity with third-party systems and services.
• Design, build, and operate scalable, cloud-native systems on Azure with a focus on reliability, performance, and observability.
• Contribute to a domain-driven architecture where flexibility, versioning, extensibility, and long-term maintainability are core design principles.
• Design, build, and maintain clean, well-documented, production-grade APIs intended for public or partner consumption. This includes thoughtful versioning strategies, backward compatibility considerations, and API lifecycle management.
• Contribute to AI-powered features where appropriate, including LLM-based workflows and retrieval-driven functionality.
• Use and evaluate AI developer tooling, including Copilot, Claude Code, Codex, and similar tools as part of daily development workflows. We support flexibility and allow developers to use tools and environments that help them work effectively while maintaining engineering standards.
  

Required Qualifications

• A degree, diploma, or certificate in computer science, software engineering, or a related field.
• 3 or more years of professional software development experience.
• Strong experience with C# and .NET Core.
• Experience building modern front-end applications using React and TypeScript.
• Strong understanding of software design principles, patterns, and clean architecture practices.
• Comfortable using generative AI developer tools to improve productivity and quality while applying sound engineering judgment and validation practices.
• Strong collaboration and communication skills.

Preferred Qualifications

• Experience designing modular, extensible systems in complex, domain-driven applications where business logic is dynamic and highly configurable.
• Experience designing clean, maintainable APIs with thoughtful versioning and long-term evolution in mind.
• Experience working with cloud platforms such as Azure.
• Experience building production LLM-powered systems, including retrieval augmented generation (RAG), embeddings, vector databases, and agent-style workflows.
• Familiarity with modern AI orchestration and agent frameworks such as LangChain, Semantic Kernel, or similar tooling.
• Experience integrating LLM systems into production applications with attention to observability, evaluation, guardrails, and performance considerations.
• Familiarity with the insurance industry or other complex, regulated business domains is an asset.

Our Technology Stack and Architecture

We primarily build using C# and .NET Core on the backend, with Entity Framework and PostgreSQL for data persistence. Our front-end applications are built with React and TypeScript. We leverage Azure for cloud infrastructure and operate in a service-oriented architecture with well-defined boundaries and clean API contracts.

Our systems are designed around modular, highly configurable components rather than tightly coupled implementations. We emphasize separation of concerns, clean code practices, and maintainable service boundaries. As the platform evolves, we prioritize scalability, observability, and long-term architectural integrity.

If you care about quality, reliability, and long-term maintainability, you will find meaningful work here.

We operate as a distributed team, with a preference for Alberta-based employees. We collaborate daily across product, engineering, and domain experts, and we come together periodically for in-person planning and team events. We value autonomy, accountability, and engineers who take ownership of their work.

You will be joining a team that treats software development as a craft, embraces modern tooling, including AI-assisted workflows, and takes pride in building production-grade systems the right way.

What We Offer

• Be part of a growing company building a modern, enterprise-grade platform for the insurance industry.
• Work alongside experienced insurance and technology professionals in a collaborative environment.
• Flexible remote work environment, with a preference for Alberta-based team members, and periodic in-person planning sessions and team events.
