Senior Security Engineering

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 Innovations, and Scale Venture Partners. We're looking for a senior security engineer who breaks things so our members never have to worry.

You will be the person who keeps our members' financial lives safe. Range handles sensitive data across investments, taxes, retirement, and estate planning. You’ll probe our AI systems, infrastructure, and applications for weaknesses before anyone else can find them. You’ll work directly with engineers to fix it. You’ll also help us think about what’s next. AI introduces new attack surfaces that most security playbooks don’t cover yet. Training pipelines, inference systems, model architectures, supply chain risks. We think really big, but we ship small and incrementally. You’ll build automated tools to scale what you do, contribute to how we measure security as a program, and help the whole engineering team raise their security instincts. At Range, security engineers are builders, not gatekeepers.

You don't just identify risks in a spreadsheet. You demonstrate them and help fix them.

You’ve spent real time doing red team operations, penetration testing, or security research. Curious about AI. You have growing expertise in AI/ML security, or you’re deeply motivated to develop it. You’re thinking about prompt injection, model poisoning, data exfiltration from training pipelines, and the attack surfaces that most teams haven’t mapped yet.

You make security feel like a partnership, not a penalty.

AI-native. You’re already using AI every day as core infrastructure. You see it as the thing that makes one security engineer dramatically more effective.

You connect every finding back to real risk for real members. 6+ years of professional security engineering experience

Deep hands-on experience with offensive security: red teaming, penetration testing, or vulnerability research

Experience assessing cloud infrastructure security, preferably AWS (EC2, ECS, RDS, S3, IAM, and similar)

Ability to develop custom tools and automation for security testing (Python, Go, or similar)

Experience analyzing and exploiting web application vulnerabilities

Bachelor's degree in Computer Science, Cybersecurity, or a related field, or equivalent practical experience

Experience with AI/ML system security: training pipelines, inference systems, model architectures

Familiarity with AI-specific attack vectors such as prompt injection, model poisoning, or data extraction

Fintech or financial services security experience

Experience building security metrics and reporting frameworks

You’d rather write a policy doc than prove an exploit.

You need a fully scoped engagement plan before you can start testing.

You’re offended by the idea that AI changes everything about this job.

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

Comprehensive leave policy for growing families

Equity & Career Growth : Salary and equity refreshes based on performance

We’ll hold your spot for 6 months - and pause your equity vesting, which resumes if you return
