Sales & Client Development Manager

At Mainstream, we're building the next generation of cloud operations by combining deep cloud expertise with AI-powered automation and intelligent operations. We're looking for a motivated Sales & Client Development Manager with a strong new business orientation to expand our client portfolio and create new business opportunities.

The primary focus of this role is proactive new client acquisition — identifying target companies, opening new opportunities, building relationships with key decision-makers, and converting prospects into long-term clients.

You will take ownership of the entire sales journey, from the first outreach and discovery conversation to solution development, negotiation, and closing, working closely with our presales and technical teams.

What You’ll Do

• Proactively identify, approach, and acquire new clients in line with Mainstream’s sales strategy and growth objectives.

• Generate new business opportunities through active prospecting, market research, networking, referrals, and direct outreach.

• Identify and qualify prospective clients and build a strong pipeline of relevant sales opportunities.

• Establish relationships with key decision-makers and stakeholders, understanding their business challenges, technology environment, and priorities.

• Own and manage the full sales cycle — from initial outreach and qualification through discovery, proposal development, negotiation, and contract closing.

• Present and position Mainstream’s solutions and services to prospective clients.

• Work closely with presales, technical, and other internal teams to translate client needs into relevant solutions and compelling commercial proposals.

• Build, maintain, and continuously develop a healthy sales pipeline, ensuring consistent progress toward defined sales and new-business targets.

• Develop relationships with newly acquired and existing clients, identifying opportunities for additional services and long-term cooperation.

• Monitor the market, competitors, industry trends, and emerging opportunities to identify new sources of business.

• Use AI and automation to improve prospecting, research, outreach, pipeline management, and overall sales effectiveness.

• Continuously develop your knowledge of cloud technologies, managed services, IT trends, and modern B2B sales practices.

• Bachelor’s degree in business, economy, or technical sciences (preferred).

• Proven experience in B2B sales, business development, and new client acquisition, preferably within IT, cloud, telecommunications, managed services, or another technology-driven environment.

• A demonstrated ability to proactively generate new business, rather than relying primarily on inbound opportunities or an existing client portfolio.

• Experience in identifying prospects, initiating contact, opening new accounts, and developing opportunities from the ground up.

• Proven ability to manage the end-to-end B2B sales process, including prospecting, qualification, solution positioning, negotiation, and closing.

• Strong communication, presentation, negotiation, and relationship-building skills.

• Ability to understand clients’ business and technology needs and work effectively with technical teams to develop the right solution.

• Strong commercial awareness and a results-driven mindset, with ownership of individual sales and revenue targets.

• A proactive, persistent, and structured approach to building new business.

• Confidence in using CRM systems, digital prospecting tools, and AI-powered solutions as part of the sales process.

• Curiosity and willingness to continuously learn about technology, cloud services, and evolving customer needs.

• Professional working proficiency in English.

Why Join Mainstream?

• Work with solutions that make a difference.

• Own your market and opportunities.

• Work alongside technology experts.

• Make a visible business impact.

• Use modern tools to work smarter.

• Build relationships that last.
