• Own the architecture of Reddit’s iOS Mobile App and make it scale to the next 100M+ DAUs. Propose ideas/solutions to reach our vision of “making Reddit’s Mobile Apps best-in-class.” • Identify the gaps in our current iOS App Architecture, and lead redesign of the iOS platform to improve modularity, performance, and quality. • Define, measure, and execute on key user-facing performance goals, specifically minimizing App Not Responding (ANR) rate, reducing app launch time (Time to Interactive/TTFF), and eliminating slow/dropped frames. • Improve observability and harden data quality for all key performance areas, including establishing reliable telemetry, monitoring, and guardrails for ANR rate, app launch time, and slow/dropped frames. • Drive a company-wide culture of performance, ensuring that every iOS engineer at Reddit has the tools and skills needed to own the performance of their product surfaces. • Mentor iOS developers across the company. • Be the go-to person for developers on complex problems in iOS development.

Role Description We are seeking a versatile Full Stack Software Engineer to join our engineering team. Reporting to the Software Engineering Manager, this is a hands-on role requiring comfort and confidence in working across the entire stack, with a particular emphasis on user-facing frontend experiences. - Build delightful, performant, and accessible user experiences for our consumer-facing applications across Web and Mobile using React and React Native. - Contribute across the stack, owning features end-to-end from frontend implementation through backend integration and experimentation. - Develop and maintain robust REST APIs using Python frameworks such as FastAPI. - Design and manage databases, including relational databases like MySQL and PostgreSQL, and NoSQL databases like DynamoDB or MongoDB. - Write well-tested, maintainable code across frontend, backend, and integration layers. - Participate in technical discussions around system design, performance tradeoffs, and long-term maintainability. - Collaborate with cross-functional teams (Product, Design) to gather requirements, design solutions, and deliver high-quality applications. - Contribute to technical decision-making regarding architecture, libraries, and tools to optimize performance and developer experience. Qualifications - Bachelor’s degree in Computer Science, Software Engineering, or a related field, or equivalent professional experience. - 3 to 6 years of professional software engineering experience in building production systems across both frontend and backend. - Strong proficiency in Python; hands-on experience with the FastAPI REST framework & Database ORM’s. - Highly proficient in JavaScript/TypeScript; hands-on experience building modern frontend applications with React. - Must have a strong grasp of HTML5 and CSS3. - Experience working with relational databases (MySQL, PostgreSQL) and NoSQL databases (DynamoDB, MongoDB). - Proficiency in writing and executing unit tests using frameworks like pytest, React Testing Library, or similar tools. - Experience integrating LLM APIs (OpenAI, Anthropic, or Gemini) into production applications. - Strong familiarity with AWS services for cloud-native application development. Requirements - An eye for design details and a passion for User Experience (UX); ability to bridge the gap between design mockups and technical implementation. - Hands-on knowledge of DevOps tools, specifically Terraform and Docker, for managing containerized environments. - Familiarity with the "AI Stack" beyond APIs—such as vector databases (Pinecone, pgvector), RAG (Retrieval-Augmented Generation) architectures, or local model inference (Ollama). - Experience in automated testing at multiple levels (unit, integration, end-to-end). - Experience with Hardware-Software integrations using services like AWS IoT. - Experience in Healthcare & SaMD applications within a regulated healthcare environment. Physical Demands - Ability to sit or stand at a desk for prolonged periods of time. - Ability to operate a computer keyboard, mouse and other related equipment. - Close vision, color vision and the ability to adjust focus are required to read code, analyze interfaces and visually identify defects.
