Staff Software Engineer, Payments Infrastructure

Staff Software Engineer, Payments Infrastructure

Zentact is building a white-label payments infrastructure platform that allows SaaS companies to embed payments into their product in weeks, not months. Behind that simplicity is a high-throughput, event-driven system handling payment orchestration, real-time + batch analytics, distributed workflows, and mission-critical reliability requirements. We’re scaling fast — and we’re hiring a Staff Software Engineer, Payments Infrastructure to help shape the architecture that supports our next stage of growth.

The Role

This is a hands-on Staff IC role. You’ll lead architecture decisions across core platform systems, design distributed systems that handle high-volume payment and analytics workflows, raise engineering standards across reliability, observability, and safe deployments. You will also mentor engineers, influence technical direction, and partner closely with product and leadership to ship safely in a mission-critical domain. This role involves deep technical ownership and no people management.

What You’ll Work On

• Event-driven systems processing large data volumes
• Real-time + batch analytics pipelines
• Workflow orchestration (Temporal-style systems)
• Safe, no-downtime deploy strategies
• Backwards-compatible APIs and data migrations
• Observability systems (tracing, metrics, structured logs)
• Scaling systems for reliability under load

If You Enjoy Thinking About

• Failure modes
• Data consistency
• Idempotency and retries
• Scaling and partitioning
• System correctness in payments-like environments

You’ll likely enjoy this role.

What We’re Looking For

You likely have:

• 8+ years building production systems
• Experience operating distributed or high-scale backend systems
• Strong system design skills
• A production-first mindset (uptime, safe changes, operational awareness)
• Experience mentoring engineers and influencing architecture

Bonus (not required):

• Payments or regulated systems
• Event-driven architectures
• Workflow orchestration tools (Temporal or similar)
• Analytics databases (ClickHouse, BigQuery, Snowflake, etc.)

We care far more about your ability to design and run reliable systems than matching our exact stack.

Tech Stack

• TypeScript (Node.js)
• React
• Event-driven architecture (Pub/Sub)
• Workflow orchestration (Temporal)
• GCP infrastructure
• Analytics + operational data systems
• tRPC
• Zod

You don’t need experience with every tool — strong distributed systems experience transfers well.

Why This Role Is Interesting

• Staff-level ownership without management overhead
• Architect systems early in their scaling curve
• Real distributed systems problems (not CRUD apps)
• Payments complexity without building a payments company
• High autonomy, low bureaucracy
• Direct influence on product direction

Why Zentact

• High impact: you’ll shape core architecture as the product scales fast
• Rapidly growing and evolving product
• Real systems problems: reliability, throughput, analytics, workflows, and payments complexity
• Build a platform that helps SaaS companies launch payments quickly with a managed solution
• Strong engineering culture: autonomy, ownership, and practical decision-making

Compensation & Benefits

• Competitive salary, based on experience and impact
• Unlimited PTO, take time when you need it, we trust adults to manage their schedules
• Fully remote-friendly work environment
• High ownership and influence in a fast-growing product
