Job description

AuthenticOne is a new-age cybersecurity startup built on the People First principle. We’re on a mission to make cybersecurity more accessible, proactive, and impactful. Our services span Red Teaming, Incident Response, Threat Intelligence, Attack Surface Management, and Cybersecurity Compliance; helping organizations stay secure in an evolving digital landscape.

At AuthenticOne, culture comes before everything else. We value integrity, transparency, teamwork, and fearless execution. If you thrive in a fast-paced, purpose-driven environment where you can directly shape growth, you’ll feel right at home here.

About the Role

We are looking for a Full Stack Software Engineer who thrives on building end-to-end products the right way — with structure, clarity, and craftsmanship.

You will work directly on the design and development of scalable, high-performance web services, client applications, while also carrying out development of the product frontend as needed. This role is ideal for someone who is deeply curious, technically strong, and driven by a growth mindset.

We believe in doing things systematically with intent, not by trial and error, and give you the autonomy and responsibility to make a significant impact on our product and solutions.

Key Responsibilities

• Design, develop, and maintain scalable backend APIs and microservices using Python (Flask / FastAPI).
• Contribute to C++ based client components, ensuring performance and reliability.
• Make enhancements or fixes on Angular/React based frontend codebases (basic frontend familiarity expected that call allow you to navigate and contribute to code, not deep expertise).
• Containerize and deploy applications using Docker.
• Propose and participate in architecture discussions and ensure best practices in design, performance, and security.
• Write clean, maintainable, and testable code following modern software engineering principles.
• Work in agile, collaborative teams — participating in code reviews, sprint planning, and retrospectives.
• Bring structured thinking, curiosity, and resilience to problem-solving and delivery.

Required Skills & Qualifications

• Bachelor’s or Master’s degree in Computer Science, Engineering, or related field.
• Strong Computer Science fundamentals — data structures, algorithms, concurrency, networking, operating systems, databases and design patterns.
• Hands-on experience with projects in Python (Flask / FastAPI preferred).
• Solid understanding of RESTful API design principles.
• Frontend:
• Understanding of Angular (or React) sufficient to navigate and contribute to an existing codebase. Any experience working on the front end is considered a plus.
• Experience deploying containerized applications using Docker and container orchestration services like Amazon ECS or Azure Container Apps/ AKS.
• Exposure to CI/CD tools (GitHub Actions, GitLab CI, Jenkins).
• Familiarity with AWS core services (ECS, S3, EC2, IAM, CloudWatch) is a plus.
• Strong analytical and problem-solving skills.
• Excellent communication and teamwork abilities.

Preferred Traits

• Hands on experience on C++, Golang.
• Growth mindset — driven to independently learn, build, and improve continuously.
• Structured and systematic in problem-solving.
• Belief in doing things the right way over shortcuts or trial-and-error.
• Resilient, hardworking, and accountable.
