What does a senior software engineer do at a startup?

A Senior Software Engineer at a startup is responsible for designing, developing, and maintaining the core software products or services. They often take on a broad range of tasks, including coding, code reviews, system architecture, and mentoring junior team members. In a startup environment, they may also contribute to product decisions, help set technical direction, and quickly adapt to changing priorities. Their role is critical in building scalable, reliable solutions while fostering innovation and collaboration within a small, fast-paced team.

What are some unique challenges senior software engineers face when working at a startup compared to a larger company?

Senior Software Engineers at startups often navigate a fast-paced, rapidly changing environment where priorities can shift quickly. Unlike at larger organizations with established processes and specialized teams, startup engineers may wear multiple hats, handling everything from architecture decisions to hands-on coding and even DevOps tasks. This role typically requires a high degree of autonomy and the ability to make impactful technical decisions with limited resources. The collaborative nature means frequent interaction with product managers, designers, and often even company leadership, creating opportunities for broad influence but also demanding strong communication and adaptability.

What are the key skills and qualifications needed to thrive as a senior software engineer at a startup, and why are they important?

To thrive as a Senior Software Engineer at a startup, you need advanced programming abilities, architectural design experience, and a solid understanding of software development lifecycles, typically backed by a bachelor's degree in computer science or a related field. Familiarity with modern frameworks, cloud platforms (like AWS or Azure), version control systems (such as Git), and agile methodologies is essential, with certifications in relevant technologies being advantageous. Strong problem-solving, adaptability, and effective communication skills help you navigate the dynamic startup environment and mentor junior team members. These skills are crucial to rapidly building scalable solutions, driving innovation, and supporting business growth in a fast-paced and often ambiguous setting.

Job description

Overview

Senior Software Engineer - Claims Platform

Works intensely across all phases of software delivery - conceptual design, detailed design, implementation, testing, and production deployment - on a large-scale enterprise insurance claims platform. Leads internal architecture discussions, collaborates closely with business analysts to clarify requirements and define technical deliverables, and contributes to the strategic direction of the software. Maintains current knowledge of market trends including AI/ML and cloud-native patterns.

Responsibilities
  • Architected and delivered a multi-tier microservices platform for enterprise insurance claims processing, spanning 30+ ASP.NET Core Web APIs organized across distinct Experience, Process, and System service layers to enforce separation of concerns and independent deployability
  • Built full-stack Blazor WebAssembly applications (MudBlazor, Fluxor/Redux state management, FluentValidation) and React SPAs for claims management portals serving adjusters, TPA users, and management teams
  • Wrote intermediate to advanced T-SQL queries, stored procedures, and schema designs across multiple MSSQL databases; applied service-oriented architecture patterns throughout the platform
  • Drove DevOps maturity through Azure DevOps CI/CD pipelines, Docker containerization, and environment-stratified configuration management (Dev UserTest Production)
  • Conducted regular code reviews to enforce quality standards, identify design issues early, and grow technical capability across the team; contributed to defining and documenting coding conventions adopted platform-wide
  • Mentored junior and mid-level engineers through pair programming and architectural guidance; developed GitHub Copilot onboarding guides and AI usage standards for developers and business analysts
Qualifications

Additional Experience (Nice to Have):

  • Designed and built a custom agentic AI workflow engine enabling configurable, multi-step AI reasoning pipelines - supporting tool execution, memory scoping, verification steps, and structured output - without hardcoded orchestration logic; applied across claims triage, coverage determination, and document analysis
  • Built and maintained a Retrieval-Augmented Generation (RAG) service backed by Azure AI Search, powering AI-assisted features including compensability and coverage determination workflows, document data extraction, photo analysis, and automated notes summarization using Azure OpenAI
