Full Stack Software Developer (work anywhere in world)

Our Mission

JustPaid is a startup on a mission to modernize the financial infrastructure that powers how companies sell to other companies.

We are building the financial operating system for the next generation of businesses.

Founders, executives, startups, and finance teams are drowning in time-sucking financial work: messy sales contracts, fragmented billing models, unpredictable cash flow, and outdated, expensive tools that slow everything down.

The financial stack today is broken.

We are not building another dashboard or another shallow app. We are building real infrastructure that sits at the core of how modern companies make and collect money.

This role is for someone who loves to learn, loves to build, and cares deeply about craft. Someone who can think through hard problems, write clean code, and isn’t afraid to make decisions. Titles matter less than impact here.

What you’ll do

• Build core product features used daily by finance teams and founders
• Work across the stack and ship to real production systems
• Collaborate closely with product, design, and customers
• Help define technical direction as the company grows

What we value

• Strong fundamentals and genuine curiosity
• Ownership mindset and high agency
• Comfort with ambiguity and fast iteration
• Clear communication and respect for users

You don’t need to check every box. If you’re smart, driven, and excited about building something important, we want to hear from you.

This is a chance to build early, build deeply, and grow alongside a small team that cares about doing things the right way.

If you want to look back one day and say, “I helped build that from the ground up,” this is that role.

Working Hours & Environment

• Working Hours: Pacific Time (PT) business hours required.
• Fully remote role.
• Required for real-time collaboration with customers, engineers, and founders
• Off-hours work are required for go-lives, escalations, and weekly when meeting with the founders
• Remote does not mean asynchronous-only — live collaboration matters

What We Value

• Strong fundamentals and curiosity
• High ownership and accountability
• Comfort with ambiguity
• Clear communication
• Respect for users and craft

You do not need to check every box. If you are smart, driven, and excited about building something that actually matters, we want to hear from you.

Interview Process

Interview Process

You’ll start with a Zoom conversation with the founders and team to see if there’s a fit.

We don’t do long, drawn-out interview loops. We keep it simple and respect your time.

If there’s mutual interest, we’ll ask you to show us something you’re genuinely excited about—anything works:

• A side project
• An experiment or prototype
• A tool you’ve built and love
• Or a walkthrough of your GitHub and the work you’re most proud of

We move fast, communicate clearly, and make decisions quickly—without unnecessary steps.

We’re especially excited to work with engineers based in the Bay Area. Build from anywhere, but if you’re nearby, even better. You’ll work with a tight, founder-led team.
