This role's mission & overview:

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.

As a Senior Software Engineer on our Delta team, you will:

• 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
• Build and maintain shared packages and reusable UI components across the CoreJS monorepo, ensuring consistency across applications
• Partner with other engineering teams to integrate Auth0 authentication, modern navigation components, and shared services across the platform
• Collaborate with product, engineering management, and architects to define right-sized scope that maximizes customer impact while minimizing engineering investment
• 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

We think a successful candidate will bring:

• Experience leading the design and implementation of major features and platform improvements in collaboration with multiple engineers and teams
• Strong cross-functional collaboration skills and a track record of partnering with product on rapid experimentation and customer feedback loops
• Experience modernizing legacy systems while balancing impactful, incremental improvements with maintaining a high quality customer experience
• 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

We encourage people of all backgrounds to apply:

_We're actively taking steps to make sure our culture is inclusive and that our processes and practices promote equity for all, including people of color, people from working-class backgrounds, women, and members of the LGBTQ+ community. We welcome and encourage applications from people with these identities or members of other historically marginalized groups.

__Research shows that women and people of color tend not to apply to jobs unless they believe they are 100% qualified and apply to fewer senior-level positions. With that in mind, we encourage you to apply if you're not sure whether you meet our qualifications. We'd love to have the opportunity to consider you!

_We encourage applications from parents, parents-to-be, and those responsible for the caretaking of others. We offer paid parental leave for birthing and non-birthing parents (including for adoption, surrogacy, and foster care placement) and paid loss leave to recover from miscarriage or stillbirth. The company's HSA and wellness allowance contributions may be used toward childcare, eldercare, adoption fees, and fertility treatments like IVF, among other expenses.
