THE IDEAL CANDIDATE

We are looking for a mobile software engineer with an interest in research and development (R&D), excited about working on early-stage prototypes and proof-of-concept projects. This role sits within the Signal Collection team in the Advice & Intelligence POD, where creativity, experimentation, and problem-solving are essential.
This team plays a crucial role in developing prototypes and evaluating new technologies that can advance Entersekt’s offerings. As a mobile engineer in this team, you’ll be responsible for designing, building, and iterating on mobile-centric solutions that leverage iOS, Android, and full-stack technologies. Your contributions will help shape the future direction of the company’s products and technical capabilities.

SKILLS AND EXPERIENCE

Successful candidates for this role will generally possess the following qualifications and skills:

• 3+ years of experience in mobile development with proficiency in Java, Kotlin, Swift, or Objective-C.
• Full-stack development experience, with knowledge of TypeScript (Node.js) back-end systems and web technologies like Angular, React, or Vue.
• Experience with building POCs and prototypes, with a willingness to work in a fast-paced R&D environment.
• Strong understanding of mobile development frameworks (iOS and Android).
• Solid understanding of object-oriented (OO) design patterns, SOLID principles, and software design fundamentals.
• Exposure to Agile practices like Scrum or Kanban.
• Familiarity with mobile security best practices and secure coding techniques.
• Experience with RESTful API design and integration.
• Experience with hybrid mobile development frameworks (e.g., Cordova, Ionic).
• Knowledge of mobile SDK API design and development.
• Experience with Docker, Kubernetes, and containerization within a mobile environment.
• Understanding of cryptography and public key infrastructure (PKI) is advantageous.

THE ROLE

As part of the Signal Collection team, you’ll be responsible for developing mobile prototypes and POCs that push the boundaries of what’s possible in the digital security landscape. Working closely with R&D peers, you’ll contribute to full-stack projects involving iOS, Android, and TypeScript-based back-end systems. Specific tools and technologies aren’t prescribed, so you’ll need to be adaptable and comfortable experimenting with a wide range of development environments.
You’ll help conceptualize and build technical prototypes, gather feedback from stakeholders, and iterate rapidly to refine your solutions. You’ll also be expected to take ownership of research into cutting-edge mobile technologies and evaluate their potential application in Entersekt’s core business.

RESPONSIBILITIES

• Prototype Development: Design and implement mobile-centric POCs and prototypes across Android, iOS, and web-based environments.
• Collaboration: Work closely with cross-functional R&D teams to brainstorm, design, and develop innovative solutions that align with Entersekt’s strategic goals.
• Technology Research: Research and evaluate emerging technologies and frameworks that could enhance mobile and full-stack development.
• Full-stack Contribution: Contribute to backend development using TypeScript-based systems, and web development as needed for holistic solution building.
• Architectural Input: Participate in architectural discussions, providing insights on mobile engineering, security, and best practices.
• Iterative Development: Take rapid feedback from stakeholders and team members to iteratively improve POCs and prototypes.
