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.

What is the difference between Mobile Rust Backend Developer vs Mobile Backend Developer?

AspectMobile Rust Backend DeveloperMobile Backend Developer
Required SkillsRust programming, backend development, mobile integrationJava, Kotlin, Swift, backend development
Work EnvironmentMobile app backend, Rust ecosystem, cloud servicesMobile app backend, various languages, cloud services
Industry UsageEmerging in high-performance mobile appsWidespread across mobile app industries

The main difference between a Mobile Rust Backend Developer and a Mobile Backend Developer lies in the programming languages used. The Rust role focuses on high-performance, memory-safe backend services using Rust, especially for mobile app integration. In contrast, Mobile Backend Developers typically work with languages like Java, Kotlin, or Swift, depending on the platform. Both roles involve backend development and cloud services, but the choice of language and specific expertise distinguishes them.

Job description

We are hiring a Founding Software Engineer in San Francisco.

We are building a small, talent-dense team. This role will define the engineering archetype at Unsiloed AI and set

the ceiling for the team. We strongly believe technical DNA compounds (or degrades) with every hire and hence

the first few matter disproportionately. You will be expected to operate proactively, take full ownership, and

independently drive systems from idea to production.

What you Will Do

As a Founding Software Engineer, you will own the entire technical stack end-to-end, from core infrastructure

and production systems to deployment, reliability, and developer experience.

  • Architect, build, and scale core backend systems powering document intelligence and VLM-based workfows

  • Own production infrastructure end-to-end: deployments, monitoring, performance, reliability

  • Design and operate high-throughput, low-latency services in real production environments

  • Take systems from R&D production enterprise scale

  • Build and maintain cloud and on-prem deployments (Docker, Kubernetes, Helm) for enterprise customers

  • Establish best practices for CI/CD, observability, debugging, and incident response

  • Work closely with the founders and research team to turn research prototypes into production-grade, scalable

    systems.

What We are Looking For

This role is backend & infrastructure-heavy. You should have most of the following:

  • Experience building and operating scaled production systems

  • Strong backend engineering skills (Python required; C++/Rust is a major plus)

  • Experience with distributed systems (microservices, parallel processing, queues, caches like Redis)

  • Deep familiarity with cloud infrastructure (AWS, GCP, Azure)

  • Hands-on experience with Docker, Kubernetes, Helm, and infrastructure-as-code (Terraform / Pulumi)

  • An ownership mindset

  • Nice to have: Experience serving ML / VLM / GPU-heavy workloads

Benefts & Perks

  • Competitive compensation + equity

  • Full health insurance coverage

  • Free company laptop

  • Doordash/Uber credits
