About the Role:

We're building a new platform from scratch — a 0→1 product combining marketplace infrastructure, B2B SaaS, and high-volume content management, designed to handle significant transaction volume and billions of data points annually. This is a true full-stack role with roughly equal weight on frontend and backend. You'll own features end-to-end — from database schema through API design to the UI — working closely with our Staff Engineer, designer, and product stakeholders. Hands-on IC today, with a clear path toward technical leadership as the team grows.

Key Responsibilities:

• Own features end-to-end — design, build, ship, and maintain
• Build across the full stack: backend services, APIs, and polished frontend UIs in roughly equal measure
• Implement multi-tenant architecture with strong data isolation and security
• Integrate external APIs — social platforms, payment providers, partner systems
• Collaborate with our designer to deliver responsive, high-quality user interfaces
• Contribute to technical design and architecture discussions
• Review code and help raise the team's quality bar
• Mentor junior engineers as the team grows

Minimum Qualifications:

• CS degree or equivalent practical experience
• 5+ years shipping production software, with meaningful time on both frontend and backend
• Polyglot mindset — proficient in at least one backend language and one frontend framework; comfortable picking up new ones
• Strong frontend skills: component architecture, state management, data fetching patterns
• Experience with relational and/or NoSQL databases, RESTful or RPC-style APIs
• Comfortable with cloud infrastructure and containerised environments
• Demonstrated ability to own features independently and ship iteratively
• Clear communicator who gives and receives feedback well

Preferred Experience:

We work primarily in Go and TypeScript/React — familiarity with our stack is a bonus, not a blocker.

Full-Stack & Frontend:

• Strong TypeScript and React — hooks, component design, performance optimisation
• CSS frameworks (Tailwind or similar) and component libraries
• Client-side data fetching and routing patterns
• Data visualisation for dashboards and analytics UIs
• Go for backend services.
• TypeScript/React with Tailwind CSS and TanStack Query/Router.

Backend & Data:

• Multi-sided platform or multi-tenant SaaS experience

• Background job processing — queues, async workflows, distributed task scheduling
• Event streaming or messaging systems
• Fraud detection, trust & safety, or anomaly detection
• PostgreSQL; NATS JetStream or Kafka for messaging
• Protocol Buffers with ConnectRPC or gRPC

Infrastructure & Observability:

• Cloud infrastructure (AWS, GCP, or Azure)
• Container orchestration (Kubernetes or equivalent)
• CI/CD pipelines and GitOps workflows
• Observability tooling — distributed tracing, structured logging, metrics
• Kubernetes/EKS, ArgoCD, and Terraform
• OpenTelemetry instrumentation and Datadog

Environment:

• Startup / 0→1 experience: fast-paced, ambiguous, resource-constrained
• ML or automation feature integration.

Why This Role:

• 0→1 build: shape the platform architecture from day one.
• High ownership: lead significant features end-to-end with real autonomy.
• Complex domain: marketplace, payments, content, and automation in one product.
• Equal frontend/backend split — no siloing into one layer.
