What does a domain architect do?

Domain architects are the deep divers of specific technological areas. Whether it's 'Data Services,' 'Process Design,' or 'Integration Services,' their expertise lies in their chosen domain.

Their role is pivotal in ensuring that domain-specific problems are addressed with precision, efficiency, and innovation.

What is the paid salary for each role?

Salaries can vary widely based on geography, industry, and experience. However, on average:

  • Enterprise architects: Often regarded as one of the top-tier roles in IT, enterprise architects command a high salary due to their strategic importance. On average, they can earn between $120,000 to $180,000 annually. In larger corporations or in high-demand industries, this figure can go even higher, with some experienced enterprise architects earning upwards of $200,000.
  • Domain architects: Given their specialized knowledge, domain architects also have competitive salaries. Depending on their specific domain (e.g., Data, Security, Application) and their experience, they can expect to earn between $100,000 to $160,000 annually. Those with niche expertise or in high-demand areas can see salaries at the higher end of this range or even beyond.
  • Developers: Developers' salaries can vary widely based on their expertise, the technologies they work with, and their years of experience. Entry-level developers might start at $50,000 to $70,000, while mid-level developers can earn between $70,000 to $100,000. Senior developers and specialists, especially those proficient in high-demand technologies, can earn between $100,000 to $150,000 or more annually.

What are the must-haves for each role?

Enterprise architects should have a holistic understanding of both business and technology, leadership skills, and the ability to drive digital transformation initiatives.

Domain architects need in-depth knowledge in their domain, continuous learning to stay updated, and the ability to collaborate with both technical and non-technical stakeholders.

Developers must have strong coding skills, problem-solving abilities, and a keen eye for detail. Collaboration and adaptability are also key traits, given the ever-evolving nature of technology.
