About DualEntry

Founded in 2024, DualEntry is one of the world’s fastest-growing AI startups.

At DualEntry, the future of finance is being written today. ERP is one of the largest fintech markets in the world ($220,000,000,000+). Yet, tens of thousands of companies are still using on-premise systems, and the industry has not seen new entrants in more than 30 years.

Our AI-native ERP lets accounting teams achieve more in less time. $5M-ARR businesses to NYSE-listed companies trust DualEntry to automate away manual data entry work with AI. We’re finally making the one-person finance team a reality and putting the pain of legacy ERPs from the 1990’s in the past.

We operate with urgency and ownership. We move fast.

Why This Role Matters Now

Since starting 18 months ago, we’ve raised $100,000,0000+ from world-class investors such as Lightspeed Venture Partners, Khosla Ventures, Contrary Ventures and Google Ventures, as well as more than 20 angel investors who’ve built, scaled, and exited some of the most impactful companies of the last decade.

We got there by moving incredibly fast and hiring an exceptionally sharp, hard-working and deeply committed team from leading tech and accounting companies — Ramp, Meta, Microsoft, Lyft, PwC, Deloitte, J.P. Morgan, Bloomberg, Sage, Xero and Intuit. And some of us don't have a fancy logo on our resume and are here for a shot to prove ourselves.

We’re a small team, growing fast with huge momentum - join early.

This is an intense, hands-on role with full ownership. We expect you to push for excellence and raise the bar.

📍 Location: Remote - this role is available across all countries with 4hr+ overlap for the US ET timezone (NYC HQ)

Where you'll create impact

• You’ll own end-to-end execution for backend systems and infrastructure
• You’ll build APIs, services, and real-time systems handling complex accounting logic
• You’ll collaborate with founders, product, and frontend engineering to turn complex workflows into secure, performant systems
• You’ll design, implement, and ship production-ready features at high speed
• You’ll manage data migrations, scaling challenges, external integrations, and end-to-end reliability
• You’ll drive measurable outcomes that accelerate DualEntry’s product velocity and stability

What sets you up for success

• Hardcore work ethic and high agency
• 8+ years of experience in backend engineering
• Proven track record in high-growth, high-ownership environments
• Strong skills in PostgreSQL, SQL, ORMs, migrations, and schema design
• Experience with AWS or comparable cloud infrastructure
• Strong API design and testing experience
• Understanding of CI/CD, deployment, and production readiness
• Bonus: expertise in Python and modern frameworks (FastAPI, Flask, or Django)
• Ability to manage complex systems with evolving requirements
• Fluent English (C1+) with clear 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

• 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 culture
• High-trust environment with high expectations
• Ambitious mission - ERP is one of the largest B2B software markets in the world ($220bn per year), this is a once in a lifetime opportunity to build the next generation ERP in an industry that has not seen new entrants in 30+ years

Benefits & Perks

• Base Salary: $150,000 - $250,000 USD
• Equity: $50,000 - $80,000 USD
• Contract type: B2B
• Remote-first team - the fastest team you will have ever worked with

• Work where you feel most productive at co-working spaces or from your home office with support for setup, internet, and phone.
• Plus, wellness perks and more to make your workday even better!

We hire the best, expect the best, and give you the masterclass of your career - an archaic and huge industry like ERP only goes through a restructure like this once in a lifetime. It’s hard, it’s intense, and it’s the most rewarding work you’ll ever do.

If you’re hungry, driven, and ready to build something massive, climb aboard!

At DualEntry, we believe great products come from diverse teams. We’re an equal opportunity employer, and we’re committed to a culture where everyone feels included, supported, and able to do their best work.

About Us

We are a US-founded early stage start-up with an R&D team located in Europe. Our mission is to make learning accessible, relevant, and individualized to keep up with the changing world. We are developing a personalized virtual trainer experience, integrating generative AI and learning engineering to build a VR simulator for immersive hands-on skills training. Our learning engineering approach customizes content and feedback in real-time, directly improving learning outcomes.

We're looking for a Senior Unity engineer to help build the client-side infrastructure of our training platform. This is not just one-off application work. You will build the client foundation that powers VR training simulations today, and additional client targets over time, connecting it to our server according to a defined client-server architecture. The role demands strong application architecture, on-device services, and performance optimization skills.

The Role

This is a hands-on individual contributor role focused on building and evolving key components of our platform's client-side architecture. You will build client infrastructure against a defined server-client architecture in which the server owns authoritative simulation state and logic, connecting the client to the server per spec and reflecting server-owned behavior faithfully on the device.

Key Responsibilities

• Own and drive key components of the Unity VR client architecture so they generalize across training simulations and, over time, additional client targets, rather than serving a single application.
• Build client-side infrastructure that connects to the server according to defined contracts and reflects server-owned state and behavior on the device.
• Co-design the client-server API with the backend, defining the data contracts.
• Develop tooling that supports content creators and other developers working on the platform.
• Use AI coding assistants as part of day-to-day development, and build and maintain the pipelines and validation that make their output reliable.
• Make pragmatic architectural decisions and manage technical priorities effectively in a fast-paced, ambiguous startup environment.

Requirements

• Demonstrated professional Unity and C# experience, ideally 5+ years, with a track record of shipping complex applications or products.
• A portfolio demonstrating experience architecting and refactoring large-scale Unity projects.
• Direct experience building for VR, in particular Meta Quest.
• A track record of building generic, reusable infrastructure and frameworks, not just one-off features.
• Comfort working within a defined client-server architecture and with established API contracts.
• A proactive and adaptable mindset suited for the dynamic and evolving environment of an early-stage startup.
• Excellent communication and collaboration skills in English, with experience working effectively in a remote, culturally diverse team.
• A genuine interest in using technology to enhance learning and education.

Nice To Have

• Experience targeting additional client platforms such as WebGL.
• Experience with data-driven or reactive component systems.

What We Offer

• A high-ownership role with direct influence on product direction, architecture, and user experience, and on company culture.
• A senior opportunity to build a platform from the ground up and contribute to its growth and commercialization.
• The flexibility of a fully remote position, with working hours flexible across European time zones rather than tied to US hours.
