  • In-depth knowledge of JavaScript (NextJS/React/Node) technologies, SaaS services, and Cloud (AWS, Azure, GCP) services
  • Top-notch communication skills in both written and spoken English
  • Great time management and planning skill
  • Eagerness to work in a fast-paced environment and build technical solutions for our clients
  • Positive attitude to learning new skills
  • Having prior experience managing a team
  • Having prior experience in leading the design, development, and deployment of scalable web applications
  • Have collaborated with cross-functional teams, including designers, product managers, and other developers, to deliver high-quality products
  • Provide strategic consulting to clients, offering innovative solutions to meet their business challenges
  • Present technical concepts and solutions to both technical and non-technical stakeholders

Nice-to-have skills & qualifications:

  • Understanding of security practices
  • Interest in enforcing and improving company best practices, standards and policies related to software development
  • Skills and interest in project management, UX design or quality assurance

We offer an enjoyable and professional work environment, flexible working hours, personal development opportunities, and a competitive salary with benefits.

IONA embraces diversity and is committed to equal employment opportunities. Our people come from varied backgrounds, speak various languages, and have different gender identities, sexual orientations, and abilities.

We take measures to counteract systemic bias in the interview process, which includes structured interviews with peer-reviewed home assignments for technical roles. This helps us be more objective when assessing the skills needed to do the job.
