    πŸ‘€ TL;DR

    • Elite team of BE engineers building complex AI accounting & fintech product
    • Huge momentum, growing fast, huge product & AI roadmap
    • High-speed development - one of the fastest teams on the planet
    • Comp: $110k-$175k USD base + $40k USD equity ($150k-$215k USD total)
    • Backed by top San Francisco & New York VCs
    • Remote with in-person meetups & daily New York EST timezone overlap
    • Founders built & exited prior company at 100M ARR and 350+ people

       

    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    The current accounting software is outdated, overpriced, and inefficient, burdened by manual processes.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 β€” 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 β€” 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next wave of enterprise infrastructure: AI-powered, automation-first, and built for mid-market finance teams tired of outdated tools.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.

     

    πŸ“ 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 β€” 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 β€” with full visibility and real responsibility

     

    Compensation & Benefits

    • Base salary: $110K–$175K USD
    • 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 β€” we’d love to hear from you.
