Full 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
Ignacio shaped the baseline of our integration framework from scratch in a single weekend, then spent most weekends - while coordinating the team - shipping what was never on the roadmap: webhooks, a search engine for millions of transactions, and Puma itself
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

Danylo took ownership of our bank connection engine end to end and rebuilt it from scratch over a weekend
