Senior/Staff Backend Engineer (Remote)
Why This Role Matters Now
The current accounting software is outdated, overpriced, and inefficient, burdened by manual processes. DualEntry is the AI-native ERP for Finance teams — and we’re looking for experienced backend engineers to accelerate our roadmap development. You’ll architect features and systems end to end at an incredible pace.
This is an opportunity to own critical infrastructure at the early stage of a category-defining AI company. Build the first, true AI accounting product with your own hands - alongside our elite team.
About DualEntry
Founded in 2024, DualEntry is one of NYC’s fastest-growing AI startups, backed by top-tier VCs and 30+ unicorn founders.
Our founding team previously scaled a startup from $2K in savings to $100M ARR and a successful exit — after raising $380M+ in funding.
Now, we’re building the next wave of enterprise infrastructure: AI-powered, automation-first, and built for mid-market finance teams tired of outdated tools.
We move fast, deploy to prod daily, and build with a deep sense of ownership.
📍 Location: Remote with overlap for US ET timezone (NYC HQ)
Where You’ll Create Impact
Design and build core backend systems using Python
Build APIs, services, and infrastructure that handle real-time, business-critical and complex accounting logic
Launch production-ready features from scratch, including CI/CD pipelines and deployment
Work with product to turn complex finance workflows into performant, secure systems
Manage complexity in a business-logic-heavy product, including data migrations and scale challenges
Integrate third-party tools and external systems — proactively managing edge cases and risk
Own your work from architecture to testing, monitoring, and post-release care
How You’ll Work
You’ll collaborate with:
Founders, to understand core use cases and product priorities
Product, to co-design features from first principles
Frontend Engineers, to ensure seamless delivery across the stack
You’ll work independently, make architectural calls, and deploy to production every day (!).
What Sets You Up for Success
8+ years of experience in backend engineering
Deep experience with complex business logic products
Proficient in Python and a modern web framework (FastAPI, Flask, or Django)
Experience deploying on AWS (or similar cloud infrastructure)
Strong database skills: PostgreSQL, SQL, ORMs, migrations, schema design
Experience building and testing robust APIs
Solid understanding of software lifecycle, CI/CD, and production-readiness
Ability to manage complex systems with evolving requirements
Fluent in English (C1+) with strong written and verbal communication
How You Operate
Pragmatic: you like to move forward and make decisions based in reality (not theory). We don't debate if Cassandra has the most theoretical scalability -- we use Postgres until it breaks
Hard working: 'You can work long, hard, or smart, but [here] you can't choose two out of three" - Jeff Bezos. We wrote this job post during the weekend
Curious: you love to learn, are highly curious about new frameworks and solutions to engineering problems
Fast-moving – You deploy daily, iterate quickly, and never wait for permission
Why You’ll Thrive Here
You’ll help build the foundational backend of a product with massive market pull
You’ll work with a high-trust, high-speed team that cares about clean code and clear ownership
You’ll see your work go live weekly and shape how modern finance teams operate
You’ll grow fast — with full visibility and real responsibility

Equity: ~$50K+ USD
B2B contract (regular employment contract available)
Remote-first team - the fastest team you will have ever worked with
15 PTO days + 12 public holidays
Visa sponsorship option for relocation to NYC within 2 years
Freedom, autonomy, and impact from day one
We have only 2 backend engineering seats left on the team.
If you're excited to build systems that power AI and build the first true accounting AI product with your own hands — we’d love to hear from you.
Don't let this one get away.
