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
