Business Development Coordinator / Proposal Coordinator

NOTE: Candidates must be able to work in-person at our St. Louis office four days a week.

Atomicdust is looking for someone who can make business development feel like having coffee with a friend who happens to need killer marketing. You’ll be the bridge between “Hey, we need help” and “Here’s exactly how we’ll make that happen”—and help prospects and clients feel guided, relaxed and appreciated along the way.

This is a junior- to mid-level position, with the ability to expand and grow your role as you become proficient in your responsibilities.

• Be the first point of contact for inbound leads, scheduling qualification calls between the lead, yourself and a member of our leadership team
• Listen strategically during meetings with leads to understand project goals, scope and approach
• Build comprehensive proposals based on project scope, working with leadership to ensure accurate pricing and approach
• Coordinate the entire sales process from initial contact through signed contracts, including follow-ups, presentations and client gifting
• Handle contract coordination, customizing payment terms and routing any client redlines to internal teams for review
• Keep deals moving forward, juggling timelines, internal teams and client expectations

• Client-facing experience, or at least extreme comfort when talking to new people. This role will interact heavily with prospective clients, and their experiences with you will give them a glimpse of what it’s like to work with our team.
• Excellent writing and communication skills that get your emails opened and proposals accepted
• Strategic thinking to connect client challenges with the right solutions
• Strong listening skills paired with the confidence to guide clients
• Personable, professional and dynamic demeanor that makes clients feel comfortable and confident in our team
• Acute attention to detail to ensure proposals and contracts are error-free, comprehensive and live up to Atomicdust standards
• Standard tech comfort with platforms like Google Workspace, Microsoft Office and Slack, and willingness to learn new platforms (HubSpot experience a plus)
• Proposal coordination experience and proven ability to meet deadlines without constant hand-holding
• Hunger to continuously improve—both your own skills, and our agency processes and results
• Ability to work in-person 4 days/week at our office in Midtown St. Louis.
• Bonus points if you have experience at a design/marketing agency or understanding of branding, web design and marketing.

You’ll work with smart people who care about doing great work, connect with interesting clients across industries, and play an important role in growing our business. Atomicdust has good work-life balance compared to most agencies and the kind of culture where people actually want to show up to work.

Here’s a few of the benefits:

• Employee Medical, Dental, Vision, Long/Short Term Disability, and Life/ADD insurance for yourself with the premium paid in full by Atomicdust
• Dependent Medical, Dental and Vision Insurance with 75% of the premium paid by Atomicdust and 25% deducted from paychecks on a pre-tax basis
• Paid time off for vacation, sick time and holidays, typically including the week between Christmas and New Year’s Day, contingent on client workload
• Additional vacation accrued for each year working at Atomicdust
• Simple IRA with a corporate match equal to the amount of your Simple IRA contributions, up to 3% of your salary
• Occasional team trips to Cancun—without any trust falls or team-building exercises
