Job summary

DualEntry is seeking a senior full-stack engineer in New York to own end-to-end customer projects, build durable Temporal workflows, and integrate diverse systems. You will work with Django, DRF, PostgreSQL, and modern frontend stacks (Next.js, React with TypeScript) while maintaining strong customer collaboration and delivering high-impact solutions.

You will also contribute to internal tooling, optimize data pipelines, and help productize successful integrations for scale, with relocation

Qualifications

• 5+ years shipping production full stack software, end to end and unsupervised.
• Django and DRF, plus PostgreSQL beyond ORM defaults.
• Next.js and React with TypeScript.
• Durable workflow experience. Temporal preferred but Celery is fine.
• Direct customer exposure on past experiences. You have sat with a customer, scoped the problem with them, and shipped against it.
• Experience with third party APIs, webhooks, rate limits, reconciling two systems that disagree.

Responsibilities

• Build and own end-to-end customer projects from discovery to deployment.
• Build migration and integration pipelines on Temporal that are idempotent, resumable, and auditable.
• Model and load customer accounting data into Postgres correctly, including reconciliation with existing systems.
• Develop internal tooling to automate recurring tasks and improve efficiency.
• Feed patterns back into the core product and productize or hand off what becomes permanent.
• Compress the path from customer requests to shipped solutions.

Job description

Where You'll Create Impact

• Build!
• Embed on named customer projects and own them end to end: discovery, design, build, deploy and verify
• Build migration and integration pipelines on Temporal that are idempotent, resumable, and auditable
• Model and load customer accounting data into Postgres correctly, including reconciling against their existing system
• Build internal tooling so recurring one-offs stop being one-offs
• Feed patterns back into the core product, and productize or hand off anything that becomes permanent
• Compress the path from “customer requested” to "shipped"

What Sets You Up for Success

• Hardcore work ethic and high agency
• 5+ years shipping production full stack software, end to end and unsupervised
• Django and DRF, plus Postgres beyond ORM defaults. You read query plans and you have run migrations against live data with customers on it
• Next.js and React with TypeScript
• Durable workflow experience. Temporal preferred but Celery is fine
• Direct customer exposure on past experiences. You have sat with a customer, scoped the problem with them, and shipped against it
• Experience with third party APIs, webhooks, rate limits, reconciling two systems that disagree

Nice to Have

• Accounting, ERP, or fintech domain knowledge: double-entry, chart of accounts, close, AP/AR, revenue recognition
• Prior forward deployed, applied, or special projects experience
• Judgment about when to ship a script versus build a system

Why You’ll Thrive Here

• Significant equity ownership in one of the top AI companies in the world
• You’re joining early and will grow with DualEntry
• Your feedback shapes the product directly
• High-speed, high-trust environment with high expectations

Meet the Team

• Marcin took a non-existent tax structure and built it end to end, setting the north star for how the team keeps improving it on top of it; modular and robust, always setting the bar for the rest
• Puhiza grew her team from one to full capacity, while owning our integration framework. The queen of I/O on our platform
• Danylo took ownership of our bank connection engine end to end and rebuilt it from scratch over a weekend

Compensation & Benefits

• Equity: $60,000 - $80,000
• Base salary: $160,000 - $270,000
• Medical, dental & vision insurance
