Company:
Buildfunctions provides a simple solution to serverless computing, enabling developers to build, deploy, and scale serverless functions designed for AI at a rapid pace — all without worrying about infrastructure or servers.
Role:
We are seeking visionary Founding Engineers to join our core team.
This is an equity-based role with the potential for a salary upon successful fundraising.
We’re looking for individuals with deep technical expertise and a proven track record of building serverless compute products — engineers who excel in fast-paced startup environments and are driven to shape the future of AI compute.
This role owns the control plane and application-level infrastructure of the platform. It focuses on orchestration, correctness, scalability, and reliability of CPU/GPU workloads across a distributed cloud system, sitting between customer-facing surfaces (SDK, Web App, APIs) and the low-level execution layer (MicroVMs, bare metal, performance systems).
Responsibilities
- Own the platform control plane, including backend services responsible for job orchestration, lifecycle management, request routing, and coordination between customer requests and CPU/GPU execution.
- Design and maintain backend APIs (REST and streaming) that power the SDK, compute infrastructure, web app, and internal services, ensuring correctness, observability, and backward compatibility.
- Build and operate Node.js/TypeScript services that manage job submission, scheduling signals, capacity-aware admission, scaling decisions, retries, and failure handling across a distributed system.
- Own cloud infrastructure glue, including AWS resources such as EC2, EFS, autoscaling groups, AMIs, networking, Route 53, IAM, load balancers, and service-to-service connectivity.
- Implement and maintain autoscaling logic, capacity planning signals, and coordination with low-level infrastructure systems to ensure reliability under variable load.
- Ensure platform reliability and correctness, including error handling, retries, idempotency, consistency guarantees, and graceful degradation during partial failures.
- Build observability into the platform, including structured logging, metrics, tracing hooks, and operational visibility for debugging and incident response.
- Collaborate closely with the MicroVM Infrastructure team, consuming low-level capabilities (VM lifecycle, startup readiness, execution signals) without owning kernel, hypervisor, or image internals.
- Participate in on-call and incident response, diagnosing platform-level issues across services, infrastructure, and cloud environments.
Qualifications:
- Strong backend engineering experience with Node.js and TypeScript, including building production systems that handle concurrency, streaming data, and long-running processes.
- Experience designing and operating distributed backend systems, with a strong understanding of failure modes, retries, backpressure, idempotency, and state management.
- Proven experience working with AWS infrastructure and infrastructure-as-code (Pulumi or equivalent).
- Experience building and operating control plane systems that coordinate work across multiple services or compute nodes.
- Strong understanding of cloud-native operational concerns, including deployment pipelines, CI/CD, environment promotion, rollbacks, and observability.
- Comfortable debugging complex production issues across application code, cloud infrastructure, and distributed services.
- Solid Linux fundamentals and systems intuition, without needing to be a kernel or performance specialist.
Industry Insight:
AI and machine learning are advancing at an unprecedented speed. We are looking for someone ready to move quickly, as there are excellent industry opportunities happening in the near future.
Compensation:
Equity stake based on experience, contributions, and other factors. Details will be shared during interviews. Salaried positions are expected once funding is secured.
