Job description

Parasail is redefining AI infrastructure by enabling seamless deployment across a distributed network of GPUs, optimizing for cost, performance, and flexibility. Our mission is to empower AI developers with a fast, cost-efficient, and scalable cloud experience—free from vendor lock-in and designed for the next generation of AI workloads.

The Role

We looking for a Senior Fullstack Engineer who wants to own large surface areas of product from database to pixel. Youll build the interfaces, APIs, and systems that thousands of AI engineers interact with daily — from our real-time inference dashboard and model deployment console to the orchestration APIs that route workloads across a global GPU network.

This isnt a role where youl be handed pixel-perfect mocks and asked to implement them. Youll shape what we build and how it works, collaborating directly with founders and infrastructure engineers to turn complex distributed systems into products that feel simple and fast.

What Youll Build

• Inference Platform UI: Design and build the dashboards, model deployment workflows, and real-time monitoring views that our customers use to deploy and manage AI workloads at scale.

• APIs & Backend Services: Architect and implement the backend services that power our platform — model serving endpoints, usage metering, billing integrations, authentication, and developer-facing APIs.

• Orchestration Interfaces: Build the frontend and API layers on top of our GPU orchestration engine, giving users intuitive control over routing, caching, scaling, and cost optimization across our global network.

• Developer Experience: Own the end-to-end developer experience including API documentation, SDK design, CLI tools, and onboarding flows that make Parasail the easiest inference platform to adopt.

• Real-Time Systems: Implement streaming interfaces (SSE/WebSockets) for real-time inference responses, live cost tracking, and deployment status updates.

• Data & Analytics: Build internal and customer-facing analytics — usage dashboards, cost breakdowns, latency distributions, and performance benchmarking tools.

Technical Abilities

• Frontend Engineering: Strong experience with modern frontend frameworks (React, Next.js, or similar). You write clean, performant TypeScript and care about UI/UX details — loading states, error handling, responsive design, and accessibility.

• Backend Development: Deep experience building production backend services in Go, Python, Java, or Node.js. Youre comfortable designing RESTful and gRPC APIs, working with relational and NoSQL databases, and implementing auth, rate limiting, and caching layers.

• Distributed Systems Fundamentals: Solid understanding of distributed computing principles — consistency models, fault tolerance, and scalability patterns. You dont need to be a distributed systems PhD, but you should be comfortable reasoning about systems that span multiple services and regions.

• Cloud-Native & Infrastructure: Experience with cloud platforms (AWS, GCP, or Azure), containerization (Docker, Kubernetes), and CI/CD pipelines. Bonus if youve worked with Infrastructure as Code (Terraform, Pulumi).

• Data & Observability: Experience building data pipelines, analytics dashboards, and integrating observability tools (metrics, logging, tracing). You know how to instrument systems so problems surface before customers notice.

• AI/ML Familiarity (Nice to Have): Understanding of LLM technologies, inference optimization (batching, caching, quantization), or model serving platforms like vLLM, TGI, or Triton. If you dont have this yet, youre excited to learn.

Qualifications

• 5+ years of professional software engineering experience with significant fullstack ownership (youve shipped features end-to-end, from UI to database).

• Track record of building and scaling web applications or developer platforms used by technical audiences.

• Experience working in fast-paced environments where youe had to make pragmatic trade-offs between speed and quality.

• Strong product instincts — you think about the user experience, not just the code.

• Excellent communication skills. You can explain technical decisions to non-technical stakeholders and write clear documentation.

• While deep AI experience is not required, a demonstrated ability to learn new technologies quickly and stay current with the rapidly evolving AI landscape is essential.

Why Parasail

• Massive impact at an early stage. Were a small team building infrastructure that powers thousands of AI applications. Your work will be felt by every customer, every day.

• Work at the frontier. AI inference is one of the fastest-growing and most technically interesting areas in tech. Youll work alongside engineers whove built AI companies from scratch and shipped products used by industry leaders.

• Full ownership, minimal bureaucracy. No PRDs written by someone three levels away. You1 t work directly with founders and ship to production on your own terms.

• Competitive compensation. Competitive salary, meaningful equity in a high-growth company, and benefits designed for a distributed team.

The AI inference market is projected to dwarf the training market within a few years. Parasail is building the infrastructure layer that makes this possible. If you want to build products that shape how the world runs AI, we love to hear from you.
