That’s the Butterfly Effect that inspired our name - and it’s how we approach every engagement.

What we're looking for

We’re looking for a seasoned Business Development Manager who can both hunt and farm. This is a consultative sales role, not a numbers-game outbound grind. You’ll win by understanding a prospect’s business challenges deeply and matching them to the right mix of what we do best.You’ll own the full sales cycle - from first outreach through signed contract and initial onboarding handoff - and you’ll be a key driver of the agency’s growth towards our 2026 revenue target.

What you’ll do

• Prospect, qualify, and develop new business opportunities across inbound and outbound channels
• Lead discovery calls, uncover the real business challenge behind the stated request, and recommend the right solutions
• Write and present tailored proposals; own pricing, scoping, and contract negotiation in partnership with leadership
• Manage your pipeline in HubSpot with discipline - accurate deal stages, realistic timelines, and clean data
• Identify upsell and expansion opportunities within the existing client base
• Stay involved through client kick-off and account team handoff - ensuring the relationship is set up to succeed from day one
• Maintain a strong understanding of our services, positioning, and competitive differentiation

Experience Level

• 10+ years in business development, account management, or strategy inside a marketing, branding, or digital agency
• Proven track record of meeting or exceeding sales targets in a B2B services environment
• Experience selling retained engagements, not just project work - you understand the long game
• A genuine consultative mindset: you read between the lines, not just off a pitch deck
• Strong understanding of digital marketing (SEO, paid media, content, web) - enough to hold a credible strategic conversation
• Proficiency in HubSpot CRM; familiarity with Monday.com and proposal tools
• Exceptional communication and listening skills - you’re as comfortable asking questions as presenting answers
• Comfortable operating autonomously in a small, growing agency environment

Industry Experience (preferred, not required)

• Life sciences or biotech
• Higher education
• Technology or SaaS
• Any B2B mid-market company with a complex buying process

This role is probably not for you if…

• You’re most comfortable managing a team, not building a pipeline yourself
• Context-switching and juggling multiple deal stages at once is genuinely hard for you
• You need a large SDR team or marketing engine to feed you leads before you’ll pick up the phone
• Change management and adapting to new tools and processes are a persistent challenge

Perks

• Flexible hours and fully remote work, promoting a strong work/life balance.
• 10 days of paid vacation and 13 paid holidays.
• Retirement matching plan and healthcare stipend.
• A family-like atmosphere that values personal growth.
• Opportunities to grow within a dynamic and expanding team.
