This role's mission & overview

We are looking for a Senior Software Engineer to join our Phoenix team, which is building a scalable Camp Experience platform while rapidly modernizing our core application. Phoenix exists to make our platform secure, modern, and empowering for every engineering team at Campminder. This means leading replatforming efforts that decompose a large .NET monolith into independently deployable Self‑Contained Systems, built on an event‑driven architecture with Azure CosmosDB, Service Bus, and API Management. You’ll architect the new platform for Campminder, cure legacy code of its historical issues, and hand ownership of clean, modern domains to product teams.

You’ll also contribute to our AI‑Native workflow initiatives that measurably improve speed‑to‑ship and quality across the entire engineering organization.

This is a high‑impact, high‑autonomy role for someone who thrives on solving hard technical problems that unlock velocity and quality for an entire engineering organization.

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

• Partner with product to run rapid experiments and incorporate customer feedback quickly, so we can modernize customer experience while improving our architecture.
• Lead the design and implementation of replatforming initiatives that extract domains from the .NET monolith into independently deployable systems, improving security, test coverage, code quality, and developer experience.
• Partner with other engineering teams to decompose tightly coupled domains using strangler fig patterns, event‑driven integration, and clean API contracts.
• Contribute to AI‑Native workflow projects that measurably improve delivery speed and quality.
• Design scalable, reliable portions of our event‑sourced architecture and lead the adoption of new technologies and architectural patterns that reduce cognitive load and improve build performance.
• Collaborate cross‑functionally with product, engineering management, and architects to define right‑sized scope that maximizes impact while minimizing engineering investment.
• Mentor engineers on and off the Phoenix team, rolling out best practices in testing, deployment, quality, and operationalizing software across teams.

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.
• A track record of modernizing or replatforming legacy systems. You’ve tackled high coupling, low test coverage, and aging architectures before and know how to apply patterns like strangler fig, anti‑corruption layers, and event‑driven decomposition.
• Experience working across a legacy monolith and modern greenfield services.
• Familiarity with Azure cloud services (or equivalent)—particularly event‑driven messaging, NoSQL data stores, and API gateway patterns.
• 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.

• Ability to choose where you work – remotely, in the office, or a mix!
• A variety of resources to support mental health and emotional well‑being.
• 12 weeks of 100% paid parental leave for all new parents, including via adoption, surrogacy, and foster care.
• 401(k) with 4% company matching.
• Trust‑Based (flexible) PTO (and yes, we use it!).
• $900/year wellness allowance.
• Company‑paid subscriptions, training, and support for using AI professionally and personally. We have a team dedicated to enabling our AI capabilities for our team members and our customers!

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.
