Contract Fintech Software Engineer Jobs in Reston, VA

Most wealth management is fragmented. Range is building AI-powered wealth management that actually works. One platform – investments, taxes, retirement, estate – all of it. All helping members manage financial complexity. Backed by Google's Gradient Ventures, Cathay Innovation, and Scale Venture Partners. Hyper-growth. Small team. Every person matters.

We're looking for a software engineer who understands the user's problem, architects a solution, and ships it. Sometimes the same day. Your work lives in production, not in a design doc.

At this stage, every IC engineer at Range can operate as a 10x IC. There is very little stopping you from building.

You'll use AI workflows to move faster alongside the team and customers, bringing the best solutions to life. We think really big and ship fast, without lowering the bar on quality. You'll define how engineering operates here by figuring out what's actually possible when a great engineer leans all the way into AI.

Your architecture and your code will be how this company scales. When you build something that works, we move. Engineers at Range are catalysts, turning ideas into real products and creating momentum. That's how we lead. Ship fast, learn, iterate.

A builder. You go from problem to prototype to production. You don't wait for a perfectly scoped ticket or a sprint planning meeting. You see the gap and you close it.

Craft-obsessed. You've studied how the best companies build software and have real opinions about what makes it great. Your standards are high. What you ship is clean, secure, and considered, even when you ship it fast.

Intuition-driven. You've done enough reps to trust your gut on architecture decisions, move quickly, and be right far more often than you're wrong. When the requirements aren't clear, you use judgement to evaluate tradeoffs. Always finding a way to move.

AI-native. You're already using AI every day as core infrastructure. You see it as the thing that turns one engineer into ten.

Full-stack by instinct. Frontend, backend, infrastructure. You go wherever the problem is. React, TypeScript, Node, AWS are your tools, not your identity. You pick up whatever's needed.

You care about outcomes. Every endpoint, every interaction, every system is built around how your customers will actually experience the product.

You operate independently, delivering consistent, high-quality results that align with team and company goals. You've built a reputation for good judgment — weighing trade-offs and outcomes thoughtfully before deciding. You balance immediate priorities with a customer-first mindset, and you're starting to think bigger: how does this scale, and how does it compound?

• You need a fully scoped PRD before you can start working
• You're offended by the idea that AI changes everything about this job
• You'd rather debate architecture than ship and iterate
• You optimize for consensus over conviction
• You think "move fast" means lower the bar

• Strong proficiency in TypeScript, JavaScript, Python, or other programming languages
• Experience building and operating production services on AWS or similar cloud platforms (EC2, ECS, RDS, DynamoDB, S3, CloudWatch)
• Comfortable working across the stack — frontend, backend, infrastructure
• Track record of owning features end-to-end, from design through deployment and monitoring
• Proven ability to architect, debug, and ship using AI development tools (Claude Code, Cursor, etc.) — not just prompting, but knowing when the output is wrong, why, and how to fix it
• Experience working in an agile environment and shipping iteratively

• Experience writing scalable services with Node.js
• Experience building complex web applications with React and TypeScript
• Excellent product instincts — you think about users first, not the cleverest technical solution
• Ability to break down ambiguous problems into clear milestones and deliver without heavy direction
• Experience mentoring junior engineers through code review and pairing
• Security engineering experience
• Fintech experience
• Startup experience

• Health & Wellness : 100% employer-covered medical insurance for employees (75% for dependents), plus dental and vision coverage
• 401(k) : Retirement savings program to support your future
• Paid Time Off : time to reset and recharge + most federal holidays
• Parental Leave : Comprehensive leave policy for growing families
• Meals: Select meals covered throughout the week
• Fitness: Monthly movement stipend
• Equity & Career Growth : Early exercise eligibility and a strong focus on professional development
• Annual Compensation Reviews : Salary and equity refreshes based on performance
• Boomerang Program: After two years at Range, you can take time away to start your own company. We'll hold your spot for 6 months - and pause your equity vesting, which resumes if you return
