Full Stack Developer

About the role

We're looking for a skilled full-stack developer to join our DataVault Platform team. You'll help develop, maintain, and advance our core Web 3.0 data-management platform, a multi-service system spanning a Next.js frontend, a Go REST API, and a Python AI governance service backed by PostgreSQL, Redis, and AWS S3. This is a hands-on role where you'll have real ownership over the direction of our products.

Key Responsibilities

• Build and maintain high-quality, scalable SaaS features across our Next.js (App Router, React, TypeScript, Tailwind, shadcn/ui) frontend and Go (Chi, PostgreSQL, Redis) backend.
• Design and ship REST APIs in Go, including database schema migrations, caching strategies, and integrations with third-party services (payments, KYC, blockchain, AI).
• Develop feature modules in Portal-v2 using TanStack Query, Zustand, Zod, and React Hook Form, with Vitest and Playwright test coverage.
• Work collaboratively with designers, engineers, and product to architect medium-to-large features from concept to delivery to live support.
• Troubleshoot and resolve complex issues across the full stack — frontend, API, database, and infrastructure.
• Contribute to platform concerns: authentication, permissions (Container > Workspace > Item hierarchy), observability (OpenTelemetry), and CI/CD (Bitbucket Pipelines, SSM deploys to EC2).

Qualifications

• Experience building production Next.js or React applications with TypeScript.
• Proficiency with Go, including idiomatic HTTP services (Chi, Gin, or similar) and concurrency patterns.
• Strong understanding of SQL databases (PostgreSQL experience preferred), including schema design, migrations, and query optimization.
• Experience with modern frontend tooling: Tailwind CSS, component libraries (shadcn/ui, Radix), state management (Zustand, Redux, or equivalent), and server-state libraries (TanStack Query, SWR).
• Familiarity with Redis, AWS S3, and REST API design.
• Solid grasp of software development practices including agile methodologies, version control (Git, worktrees), and testing (Vitest, Playwright, Go testing).

Bonus

• Experience with blockchain/Web3 (EVM, ERC-721/ERC-20), payments (ACH, Finxact, PayPal), KYC providers, or AI/ML integrations.
• Comfort working in multidisciplinary teams with people of diverse perspectives.
• Strong problem-solving skills and attention to detail.
