Staff Software Engineer (TypeScript / Distributed Systems)

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
