Build the payments infrastructure powering SaaS products at scale

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
Mission-critical reliability requirements

We’re scaling fast — and we’re hiring a Staff Engineer 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
Mentor engineers and influence technical direction
Partner closely with product and leadership to ship safely in a mission-critical domain

You will not be managing people — this is deep technical ownership.

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)
