About The Position

We are looking for a Senior Software Engineer to join our Delta team, which is dedicated to improving, enhancing, and modernizing Campminder's core product. Delta brings the latest technologies into our legacy platform, shipping real product value to customers while progressively replacing aging code with modern solutions. You'll work across a large C#/.NET monolith and modern TypeScript/React services, building modern product experiences that integrate seamlessly into the existing platform. Delta is where modernization meets delivery. You'll own product-facing features end-to-end, while raising the quality, security, and developer experience of the codebase along the way. You'll also be using AI-native engineering workflows (Claude Code, agent-driven development playbooks) to accelerate how quickly and confidently the team ships value to customers. This role is for someone who loves improving experiences for users and developers alike and thrives at the intersection of legacy modernization and new feature delivery.

Strong cross-functional collaboration skills and a track record of partnering with product on rapid experimentation and customer feedback loops

Strong full-stack skills spanning C#/.NET on the backend and TypeScript/React on the frontend; comfortable working across both a legacy monolith and modern greenfield applications
Experience with modern frontend tooling, shared component patterns, and testing frameworks
Strong track record of architecting scalable, reliable systems and making forward-thinking technical trade-offs
Experience identifying meaningful ways to use AI tools (e.g., Claude Code, Copilot, or similar) to increase engineering speed and quality, and enthusiasm for adopting AI-native workflows to ship customer value faster
Passion for mentoring others and rolling out engineering best practices across teams
Excels at taking large, undefined problems and turning them into concrete next steps for themselves and others to tackle

Responsibilities

Lead the Delta team in devising new and creative strategies to allow us to quickly modernize the product while delivering new value to customers rapidly
Partner with product to run rapid experiments and incorporate customer feedback quickly
Modernize legacy pages and workflows by introducing web components, React applications, and modern CSS into the existing platform, progressively upgrading the system

Champion AI-native engineering workflows (Claude Code, AI-assisted code review) to accelerate feature delivery and improve code quality across the team
Mentor engineers on and off the Delta team, championing best practices in automated testing, code quality, and progressive modernization strategies
