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)
- 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
