Mobile Rust Backend Developer information

What is a mobile Rust backend developer?

Mobile Rust Backend Developers are software engineers who specialize in building and maintaining the backend infrastructure of mobile applications using the Rust programming language. They design APIs, manage databases, and ensure that server-side logic efficiently supports mobile app features. Rust is chosen for its safety, performance, and concurrency capabilities, making it suitable for building fast and reliable backend systems. These developers often work closely with mobile app developers to deliver seamless user experiences.

How does a mobile Rust backend developer typically collaborate with mobile app and frontend teams?

As a Mobile Rust Backend Developer, you’ll regularly work alongside mobile app developers and frontend engineers to ensure seamless integration between the backend systems and user-facing applications. Collaboration often involves participating in sprint planning, clarifying API requirements, and troubleshooting integration issues. Effective communication is key, as you’ll need to provide clear API documentation, respond to integration queries, and adapt backend services to evolving app features. This cross-functional teamwork not only enhances the product’s performance but also helps you develop a broader understanding of the overall tech stack.

What are the key skills and qualifications needed to thrive as a mobile Rust backend developer, and why are they important?

To thrive as a Mobile Rust Backend Developer, strong proficiency in Rust programming, system architecture, and backend API development is essential, along with a degree in computer science or related experience. Familiarity with tools like Cargo, Docker, RESTful APIs, and database systems such as PostgreSQL, plus experience with CI/CD pipelines, is typically required. Effective problem-solving, communication, and collaborative skills help developers excel in team environments and manage complex projects. These skills are vital for building secure, efficient, and scalable backend solutions supporting mobile applications.

About Slickdeals:
We believe shopping should feel like winning. That's why 10 million people come to Slickdeals to swap tips, upvote the best finds, and share the thrill of a great deal. Together, our community has saved more than $10 billion over the past 26 years.
We're profitable, passionate, and in the middle of an exciting evolution-transforming from the internet's most trusted deal forum into the go-to daily shopping destination. If you thrive in a fast-moving, creative environment where ideas turn into impact fast, you'll fit right in.
The Purpose:
Slickdeals is seeking a well-rounded Senior II Backend Engineer to provide technical leadership and dedicated API support for our iOS and Android applications. This engineer will own complex backend initiatives, shape architectural direction, and collaborate with Mobile, Web, Product, Design, and Platform teams to deliver reliable, scalable consumer experiences.
The ideal candidate brings deep backend expertise, strong technical instincts, and the ability to modernize an existing codebase while working effectively within established patterns. You should be a quick learner with experience refactoring legacy systems and a solid understanding of A/B testing, analytics, and application performance optimization. Full-stack experience is a plus, enabling you to contribute across platforms when needed.
In this role, you will design and deliver services that power innovative mobile features, lead large-scale cross-functional initiatives, and mentor other engineers. The position is ideal for someone who enjoys balancing hands-on execution with broader technical leadership and wants to help shape the future of the Slickdeals mobile platform.
We continually explore technologies and approaches that can strengthen our products, architecture, and engineering practices. If you bring additional experience that could help us evolve our platform, we would love to hear from you.
What You'll Do:
  • Lead the design and delivery of complex APIs and backend services supporting iOS and Android applications.
  • Own backend initiatives from discovery and technical planning through implementation, rollout, and production support.
  • Partner with mobile engineers to define API contracts, dependencies, release strategies, and backward-compatibility requirements.
  • Influence backend architecture and establish patterns that can be reused across mobile products.
  • Identify technical risks early and present practical options and tradeoffs to engineering and product partners.
  • Improve the reliability, scalability, performance, security, and observability of mobile-facing services.
  • Lead technical design reviews and raise engineering standards through code reviews, testing strategies, and documentation.
  • Diagnose complex production issues that span mobile clients, APIs, data services, and infrastructure.
  • Reduce technical debt and simplify legacy systems while balancing near-term product delivery.
  • Contribute to cross-platform including web API development when business priorities require it.

Required Qualifications:
  • Experience supporting large-scale consumer iOS and Android applications.
  • Extensive professional experience in backend software development, including strong experience with PHP and a modern PHP framework.
  • Proven experience designing and operating high-traffic RESTful or GraphQL APIs.
  • Deep understanding of API contracts, versioning, authentication, authorization, caching, pagination, idempotency, and error handling.
  • Strong experience optimizing the performance of APIs that integrate internal services and relational databases, including caching strategies, API monitoring, and RDBMS query optimization, particularly with MySQL or PostgreSQL.
  • Experience implementing secure authentication and authorization using JWT or similar token-based approaches.
  • Experience with distributed systems and asynchronous processing technologies such as RabbitMQ, Valkey, Redis, Kafka, or other queue- and event-driven architectures.
  • Experience integrating mobile push notifications through Firebase Cloud Messaging and APNs.
  • Experience creating comprehensive unit, integration, contract, and API testing strategies
  • Experience with cloud platforms, containers, Docker, Kubernetes, CI/CD pipelines, and modern deployment practices, including GitHub Actions.
  • Strong production experience with monitoring, logging, alerting, incident response, and root-cause analysis.
  • Experience with feature flags, experimentation platforms, analytics tracking, and A/B testing.
  • Demonstrated ability to lead projects across teams without relying on formal authority.
  • Strong written and verbal communication skills, including the ability to explain technical tradeoffs to non-engineering partners.

Preferred qualifications:
  • Strong understanding of mobile-specific constraints, including unreliable networks, latency, app-version fragmentation, backward compatibility, and phased releases.
  • Full-stack experience with Vue and TypeScript and a modern frontend framework.
  • Experience modernizing legacy services or decomposing monolithic applications.
  • Experience influencing engineering practices across teams.

What distinguishes the Senior II level:
  • Owns ambiguous, high-impact technical problems spanning multiple teams or systems.
  • Defines technical direction instead of focusing only on assigned implementation.
  • Anticipates dependencies and risks before they affect delivery.
  • Creates reusable solutions and raises engineering standards beyond an individual project.
  • Influences architecture and execution across Mobile, Backend, Web, and Platform teams.
  • Develops other engineers through technical guidance, and knowledge sharing.

Success in this role:
  • Mobile initiatives receive consistent backend leadership from discovery through release.
  • API requirements and dependencies are identified early, reducing delivery delays.
  • Mobile-facing services become more reliable, scalable, observable, and maintainable.
  • Mobile and backend teams operate with clearer ownership and fewer coordination gaps.
  • Architectural improvements create measurable benefits across multiple projects and teams.

LOCATION: San Mateo, CA
