Our Mission and Vision
 

At Solidgate, our mission is clear: to empower outstanding entrepreneurs to build exceptional internet companies. We exist to fuel the builders — the ones shaping the digital economy — with the financial infrastructure they deserve. To achieve that, we’re on a bold path: to become the #1 payments orchestration platform in the world.
 

About the Team and Role
 

As a Node.js Engineer in the Launch Team, you’ll power the backend behind the Digital Onboarding. Our mission is to ensure Solidgate works with compliant merchants while making the onboarding experience fast, seamless, and scalable.
 

You will build the fastest path from “I’m interested” to “I’m live.”
 

Why it’s different

• You’ll reduce Time-to-Live — directly impacting growth.
• You’ll shape the evolving Node.js stack (no legacy drag).
• You’ll design resilient, durable and scalable systems targeting 99.99% uptime.
• You’ll use AI to ship faster and embed AI-powered features into the product.
   

Tech Stack

Launch is one of the first teams driving the Node.js stack at Solidgate.
 

We don’t just adopt tools — we define standards, practices, and engineering culture that other teams follow. What we use:

• Fastify — lightweight, high-performance web server
• gRPC + Protobuf — typed service-to-service communication
• PostgreSQL + Drizzle ORM — reliable data layer with a modern query builder
• Kafka (@platformatic/kafka) — streaming-first, event-driven architecture
• Vitest — unit and functional testing

Plus custom solutions: distributed locks, metrics, streamers, and more.

The stack is still evolving — meaning real influence. No legacy baggage. Just modern Node.js running on mature architectural rails inspired by the Golang ecosystem.
 

What you’ll be doing

• Designing a flexible compliance rule engine. You’ll help design a rule engine capable of supporting multiple regulatory frameworks while remaining flexible and easy to adapt as policies change. The system should also be able to detect when rule updates require re-evaluating previously approved merchants and trigger the appropriate compliance workflows.
• Building systems with full traceability. We operate on highly sensitive compliance data, where transparency and accountability are essential. You’ll build systems that provide end-to-end auditability, ensuring every action can be traced.
• Ensuring reliability of mission-critical services. The data produced by this platform powers multiple downstream systems, including financial settlement processes and banking integrations used to open MIDs for merchants. You’ll work on building services that are highly available, durable, and resilient, ensuring the reliability of critical business operations.
• Leveraging AI for smarter document processing. You’ll help introduce GenAI-powered capabilities to streamline document processing and verification flows, reducing manual work for compliance teams and significantly accelerating merchant onboarding.
   

Who you are

• Strong ownership and clear tech POV.
• You ship production-ready systems, not just features.
• 2+ years of Node.js backend experience with solid TypeScript skills.
• Confident with testing (unit/integration/e2e).
• Comfortable with distributed systems principles.
   

Nice to have: GenAI, Next.js, compliance-heavy domains (GDPR/SOC2), Golang experience.
