## About the role

#### 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.

We’re building the #1 payment orchestrator in the world — and the names behind us prove it. Clients include Bolt, Ajax, Nova Post, MEGOGO. Trusted by giants like J.P. Morgan. Ranked #2 in the “Employer of the Year 2026” award by Forbes Ukraine.

#### About the Team and Role

You'll join the **Billing team** and become part of the effort behind one of the product's core modules — the one responsible for the invoicing cycle, payment retries, subscription management, and monetization. The team is actively building Billing v2 — a global overhaul and expansion of the subscription infrastructure — and has recently grown into a full-fledged Billing Stream.

There's no legacy here — the team is building and launching the new Billing 2.0 module practically from scratch.

Your team — 1 PM, 2 Senior Engineers, 1 Automation QA, 1 Domain Analyst.

#### What you'll own

- Core Domain & Public APIs. Design and ship the foundational Products & Prices domain model and public APIs from scratch.

- Complex B2B Pricing at Scale. Build high-precision volume and graduated pricing engines for multi-tier enterprise billing.

- Bulletproof Platform Uptime. Decouple critical services from the Products API to eliminate single points of failure.

- End-to-End Revenue Recovery. Lead the automated retry engine across all invoices, recovering millions in failed payments.We rely on automated testing over manual QA — unit, integration, functional, and e2e tests are a core part of how we ship and scale safely.

We code in Go, and we're looking equally for experienced Go engineers and strong switchers from Java, Kotlin, Python, or PHP.

#### You're a great fit if you have

- 2+ years of backend engineering experience (Go/PHP/Kotlin/Java/Python/Node.js)

- Experience covering code with tests: unit, integration, functional, e2e

- Strong understanding of high-load system design principles

- Experience with PostgreSQL and queues or streams

- A proactive, communicative, independent, and result-oriented mindset

#### Nice to have

- Experience with payment systems or in fintech / financial services

- Kafka

- AWS services

- CI/CD pipelines
