VGS provides processor-agnostic tokenization solutions via secure universal token vaults, iframes, mobile SDKs, tokenization proxies, APIs, and data orchestration tooling to support payment acceptance, card issuance, PII and bank account tokenization, and other payments value-added services. Some of the use cases we enable include multi-processor Network Tokenization, Account Updater, payment orchestration, secure settlement file processing, 3DS, and Risk provider connectivity.

We are seeking a skilled and motivated Software Engineer to join our team. You will develop and maintain our migration services and enhance our internal and external file processing product.

• Uphold a high standard of engineering excellence through comprehensive testing, automated workflows, and peer reviews.
• Join a professional environment that prizes transparency, teamwork, perseverance, and modesty, dedicated to delivering exceptional results for our clients and the organization while enjoying the process.

• Communication & Stakeholder Management: Exceptional communication skills, with a proven ability to translate complex technical architectures and concepts for both technical and non-technical audiences.
• Collaboration & Prioritization: Demonstrated strong collaboration, negotiation, and prioritization skills essential for managing competing demands and driving cross-functional teamwork.
• Participate in team-based on-call rotations to maintain system reliability, actively responding to incidents, troubleshooting production issues, and conducting root cause analysis to drive long-term service improvements.

At VGS, we have a remote-first philosophy because we believe flexibility leads to great work and a healthy work-life balance. That said, if you live within 30 miles of one of our office locations, you’ll be on a hybrid schedule with some in-person time—because we’re not about being in the office every day—but we are about connection, collaboration, and the energy that comes from a great brainstorm, a team lunch, or celebrating a big win in person.

We consider applicants without regard to race, color, national origin, sex, age, religion, sexual orientation, gender identity, veteran status, marital status, physical or mental disability, or other protected classes under all local, state, and federal laws and ordinances (AA/EOE/W/M/Vet/Disabled).

Qualified applicants with arrest and conviction records will be considered for the position in accordance with the San Francisco Fair Chance Ordinance.
