About Prelude

Description
We are seeking a motivated, hands-on Software Engineer to join our engineering team. In this role you will collaborate closely with other engineers, DevOps, product managers, and QA to build and ship features that matter to Prelude's customers.
This is an individual contributor role built for someone who is genuinely excellent in the full web development stack. Depending on what we're building, you may spend a week fully immersed in Next.js crafting a complex UI, the next week deep in the Node.js/Express.js backend, or anywhere in between. The key word is fully - we need someone who can go deep on whichever layer the work demands.
This role is hybrid (Tuesday-Thursday in office) and is based in Austin, Texas.
Responsibilities
Build and maintain full-stack features across our Next.js frontend and Node.js/Express.js backend
Design and implement RESTful APIs that are clean, well-documented, and secure
Write thorough unit and integration tests - quality and reliability are non-negotiable here
Leverage AI coding tools (Claude, GitHub Copilot, Cursor, or similar) as a core part of your engineering workflow.
Collaborate with product and design to translate requirements into polished features
Participate in code reviews, giving and receiving constructive feedback
Build software that runs in and interacts with services on AWS using ECS, Lambda, S3, API Gateway, and related services
Help identify and address performance bottlenecks, bugs, and accumulating technical debt
Requirements
Experience: 3+ years of professional software development building production SaaS applications
Frontend (must be strong): Deep, production-level proficiency in Next.js and React - component architecture, state management, performance optimization, and UI polish.
Backend (must be strong): Strong experience with Node.js and Express.js, building and maintaining APIs and services.
Cloud: Practical, hands-on AWS experience (ECS, Lambda, S3, API Gateway, or equivalent)
Testing: A genuine commitment to writing tests - unit and integration
AI Fluency: Hands-on experience across the full spectrum of AI-assisted development - chat, inline code completion, and agentic workflows (e.g. Claude Code, Cursor Agents, GitHub Copilot).
APIs: Solid understanding of RESTful API design, authentication (JWT/OAuth), and security best practices
Collaboration: Comfortable in Git, agile workflows, and cross-functional teams
Communication: Strong written and verbal communication skills
Preferred
Mobile: React Native or Expo experience for building cross-platform mobile applications
MongoDB experience - schema design, querying, and aggregation pipelines
TypeScript fluency across frontend and backend
Familiarity with event-driven architectures (SQS, SNS, EventBridge)
Experience with Redis, Elasticsearch, or other specialized data stores
Experience in a startup or fast-paced SaaS product environment
Exposure to regulated industries (life sciences, healthcare, fintech)
