Senior Principal Full Stack Engineer

Our client is growing! They are an innovative technology company at the forefront of developing cutting-edge biometric recognition services to their customers without fuss or drama. They are choosy about the engineers and clients we work with. They are seeking a highly skilled Senior Software Engineer to join their dynamic team and play a pivotal role in shaping the front-end experience of our products. They are small group of remote developers based all over the world. We are choosy about the developers and clients the work with. We deliver biometric recognition services to our customers without fuss or drama. We are looking to add to the team with EST based senior developer.

As our Lead Principal Engineer – Full Stack, you’re the visionary architect steering our digital identity revolution. You’ll shape our technical strategy, collaborate with and guide diverse, cross-functional teams—from frontend and backend developers to DevOps, testing, security, and product experts—ensuring every solution we release meets two non-negotiable criteria : it works like a charm and never compromise personal data. You’ll not only craft pixel-perfect, accessible front ends and build rock-solid, cloud-based back ends, but you’ll also join forces with our sales and marketing teams to maintain our rapid momentum and showcase what a truly privacy-first experience looks like. In short, you’ll be the heart and soul of our technology vision, blending technical excellence with strategic leadership and a healthy dose of humor

This is a contract to hire , the role is 100% remote- Ideal candidate is located in the Charotte NC or Raleigh NC area but we will consider any candidates on EST or potentially CST. The salary conversion is $160,000 - $200,000 – you must be av ailable Monday-Friday 7 : 30 am-4 : 30pm EST as standard working hours.

Your day begins by leading our remote, global teams to create a high-performance, collaborative environment that inspires without micromanaging. You’ll mentor engineers across multiple time zones—occasionally reminding everyone that it’s perfectly acceptable to log off—while painting our technical roadmap with multi-year plans brimming with innovations, next-gen biometrics, and just the right mix of privacy and practicality. Staying abreast of emerging tech—from ML, cryptonets, blockchain, MPC, and ZKP to explorations in AI / ML for security and high-performance tasks using C and WebAssembly—is second nature, ensuring we remain on the cutting edge. Next, you’ll orchestrate our engineering operations by implementing Agile methodologies and streamlined CI / CD workflows that deliver secure, production-ready software—because “98% complete” simply isn’t our style. You’ll craft exceptional web applications using modern front-end frameworks (React.js, TypeScript, HTML, Tailwind CSS) and build robust back-end systems with Node.js (leveraging Express.js, NestJS, or Next.js) on a scalable, cloud-native infrastructure (AWS, GCP) through containerization and Infrastructure as Code.

And since security and compliance are everyone’s responsibility (especially yours), you’ll champion our privacy-first mindset by enforcing secure coding practices, rigorous threat modeling, and comprehensive penetration testing. From ticking off GDPR and CCPA boxes to meeting SOC 2 and ISO 27001 standards head-on, you’ll oversee risk management to ensure our systems deliver high availability, low latency, and scalability—all while maintaining maximum transparency with tools like Monday and GitHub.

To step into this role, you’ll need deep experience and a knack for leading cutting-edge, cloud-native platforms. We’re talking at least five years in senior engineering roles guiding SaaS / PaaS solutions, complex distributed systems, or digital identity solutions. You’ve mastered full-stack technologies, seamlessly balancing pixel-perfect, accessible front ends (think React.js, TypeScript, Tailwind CSS) with rock-solid back-end frameworks (Node.js with Express.js, NestJS, or Next.js) and modern API designs (RESTful, GraphQL).

Your expertise spans the cloud and DevOps realms : you’re fluent in AWS and GCP, and you know your way around Infrastructure as Code, container orchestration (Docker, Kubernetes), and CI / CD pipelines that practically run themselves—bonus points if you dream in YAML. You’re comfortable tossing around IAM, FIDO2, OAuth 2.0, OIDC, and SAML, and your track record with DevSecOps, SOC 2, PCI-DSS, and the usual cryptography suspects (FIPS 140-3, Hybrid PKI, TLS, AES) sets you apart.

But it’s not all just technical brilliance; you’re also a master of team building and communication. You’ve mentored distributed teams across multiple time zones without losing your cool or your sense of humor. You rally stakeholders around shared goals, drive Agile methodologies, and ensure even the most complex projects progress smoothly—without those dreaded midnight “urgent” emails. And if you bring extra credentials—say, an advanced degree in CS, Engineering, or a related field, or familiarity with homomorphic encryption, differential privacy, or biometric recognition (face, fingerprint, palm, UBA)—you’ll earn even more kudos. Since we serve banks too, you’ll need to pass comprehensive criminal and financial background checks to prove you’re the real deal – if this is not happening, please swipe left. And if you can decrypt a message in your head, we’ll definitely want to hear about it.

IAM, FIDO2, OAuth 2.0, OIDC, and SAML, and your track record with DevSecOps, SOC 2, PCI-DSS, and the usual cryptography suspects (FIPS 140-3, Hybrid PKI, TLS, AES) sets you apart.
