About the role
As the Lead Software Engineer supporting Frisbee Rewards, this role will serve as the backend technical anchor for the Frisbee consumer application, while also acting as the execution lead across Attain’s mobile engineering teams.
The mobile application for Frisbee Rewards, has an intentionally back-end driven infrastructure. Business logic, feature gating and much of the user experience configuration (i.e. business logic, feature gating, component arrangement and screen composition) is controlled by backend services. Mobile clients are designed to be thin rendering layers that interpret structured data and configuration delivered by the backend. This is an exciting opportunity for a senior developer who is excited about growing into a broader technical leadership role that will make an impact cross functionally.
You’ll be a great fit for the role if
- You bring strong backend engineering experience and enjoy owning systems end to end, including making pragmatic architectural decisions in ambiguous problem spaces
- You’re excited to design and build backend services that orchestrate product behavior, business logic, and user experience
- You enjoy working closely with mobile engineers and are comfortable defining APIs, schemas, and data models that power data-driven mobile clients
- You value clear communication, strong engineering judgment, and constructive feedback
- You’re interested in growing into broader technical leadership over time
What a typical week will look like
- Design, build, and own backend services (primarily Rust-based microservices) that power the Frisbee consumer experience
- Own backend systems responsible for business logic, feature flags, and UX configuration that control mobile behavior and layout
- Define and maintain clean, well-documented APIs and client-server contracts used by iOS and Android applications
- Partner closely with mobile engineers to enable fast, predictable execution and unblock delivery
- Act as technical owner for major initiatives from design through production
- Provide architectural guidance and code review across backend and mobile codebases
- Collaborate with Product and Design to translate customer needs into scalable systems
- Participate in planning, prioritization, and delivery with a strong bias toward execution
- Occasionally contribute to mobile codebases when needed
- Help establish engineering standards and raise the technical bar across the team
Preferred Qualifications
- 6+ years of experience building and owning backend systems in production environments
- Strong experience designing APIs, service boundaries, and data models
- Experience evolving complex systems and working with microservice or service-oriented architectures
- Experience operating systems in cloud environments (AWS, GCP, or Azure)
- Experience working closely with iOS and Android engineering teams
- Familiarity with backend- or configuration-driven client architectures
- Experience with gRPC, protobuf, or GraphQL
- Experience with relational databases
- Understanding of mobile performance characteristics and constraints
- Exposure to React Native
- Experience integrating third-party SDKs (e.g., analytics, scanning, CRM)
