[Hiring] Backend Engineer @Solidgate

Role Description

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.

Qualifications

• 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

Requirements

• Experience with payment systems or in fintech / financial services (nice to have)
• Kafka (nice to have)
• AWS services (nice to have)
• CI/CD pipelines (nice to have)

Benefits

• High-impact role.
• Great product: We’ve built a fintech powerhouse that scales fast.
• Massive growth opportunity: Solidgate is scaling rapidly — this role will be a career-defining move.
• Top-tier tech team: Work alongside our driving force — a proven, results-driven engineering team that delivers.
• Modern engineering culture: TBDs, code reviews, solid testing practices, metrics, alerts, and fully automated CI/CD.
• 30+ days off, unlimited sick leave, free office meals, health coverage, and Apple gear to keep you productive.
• Courses, conferences, sports and wellness benefits — all designed for ideas, focus, and fun.
