Senior .NET Developer – P3 Technology

About the Role

P3 Technology is looking to hire a Senior .NET Developer to help build, enhance, and scale the P3 Platform, a modern SaaS solution powered by .NET, C#, Angular, PostgreSQL, and AWS. This isn’t your typical heads-down developer role. We’re looking for a seasoned technologist who’s just as comfortable in client meetings as they are working with code.

In this role, you’ll architect solutions, write production-ready code, conduct thoughtful code reviews, and collaborate across product, dev, and client teams. You’ll be translating business requirements into high-quality software that powers mission-critical workflows for our customers. If you enjoy working in a fast-paced, cloud-first environment with a small, highly motivated team, you’ll thrive here.

Your Core Responsibilities

  • Design, build, and maintain scalable cloud-native applications using .NET Core, C#, PostgreSQL, and AWS
  • Architect modular, extensible solutions to complex feature requests
  • Lead and participate in code reviews, ensuring code quality and consistent standards across the team
  • Translate business requirements into technical specifications and working software
  • Actively participate in client/customer meetings, including with customer tech teams, to understand use cases and provide technical guidance
  • Collaborate with other developers, business analysts, and stakeholders on planning and delivery
  • Continuously improve development processes and AWS infrastructure with a “DevOps” mindset, including working with Terraform, Github actions, and Containerization
  • Maintain and improve security and SOC 2/HIPAA compliance of the P3 Platform, including installation of security patches and updating vulnerable packages, etc

You’re a Great Fit If You:

  • Have 5+ years of experience in .NET Core, C#, web APIs, and relational databases
  • Have experience architecting cloud-first solutions, preferably in AWS
  • Are comfortable working across the stack, from backend logic to front-end integration (experience with Angular or Vue.js a plus)
  • Are confident presenting and collaborating with customers and translating business needs into clear, executable development tasks
  • Have excellent verbal and written communication skills
  • Are curious, autonomous, and comfortable owning solutions end-to-end

Why You’ll Love Working at P3

  • You want to work on a real product solving real customer problems in a company with an explosive growth trajectory
  • You’re passionate about clean code, pragmatic architecture, and continuous learning
  • You value a transparent, no-politics work culture
  • You enjoy working with a tight-knit, experienced team
  • You want flexibility – fully remote work, flexible hours, and occasional travel to meet with clients

Benefits and Perks

  • Generous paid time off and holidays
  • Quarterly bonuses
  • SIMPLE IRA retirement plan with company match
  • Entirely remote-first work environment
  • Flexible hours and strong work-life balance
  • Opportunities to grow with a lean, agile, and ambitious team

    What's it like working at Slingshot?

    We call ourselves big kids and daredevils because we like to have fun, but we also like to challenge ourselves and our clients. Everyone here is incredibly talented and we push each other to be better. Designer and developer collaboration is a regular thing. As a developer, we want you to continue to learn and hone your craft. Designers will be talking with fellow designers and product managers on a daily basis, and hopefully adding to our wall of post-it doodles.

    As a member of the slingshot team, we expect everyone to speak their mind when they have an idea and challenge and respect their coworkers. We play Jenga tournaments, have a ball pit conference room, and begin every meeting by the ringing of a gong. We have some meetings that are all business, but our bourbon corner with the bright yellow couch and bean bags shows we balance work and fun. We are no ordinary tech company. We are who we are, because of the people who work here: a bunch of Big Kids and Daredevils.
