Chief Strategy Officer

Brussels and/or Antwerp based – Hybrid working

ABOUT US

Socialsky is one of the fastest-growing social media agencies in Belgium.
A pure player, fully obsessed with social, and proud of it.

With more than 35 strategists, creators, producers and account leads spread across two offices
(Brussels and Antwerp), we help brands grow where it really matters: on social platforms. From TikTok to Meta, from content to ads, from influence to production, everything we do is built to perform in a social-first world.

Independent by choice, Socialsky has developed its own way of working; inspired by the best practices of both big and small agencies, but always with our own twist. No copy-paste. And definitely no bullshit.

We believe in clarity, strong opinions and execution that delivers. We move fast, but never sloppy. We test, learn and iterate continuously. We’re not here to make noise for the sake of it; we’re here to build strategies that perform, scale and last. That mindset shows in our work, in the trust our clients place in us, and in the way our teams take responsibility and speak up.

We work with a strong portfolio of local and international brands, across varied scopes, and we’re proud of the long-term relationships and loyalty we’ve built with our clients.

Today, Socialsky is in a phase of strong growth and structuring. Our ambition is clear: make social-first the new standard for ambitious brands, in Belgium and beyond.

And this is where you come in.

ARE YOU THE ONE AND ONLY CSO WE’RE LOOKING FOR?

We’re looking for a Chief Strategy Officer to help take Socialsky to the next level.

This role is not about sitting on the sidelines or delivering abstract frameworks.
It’s about turning vision into strategy, and strategy into impact. For our clients and for the agency.

As CSO, you’ll be a key sparring partner for the co-CEOs and the leadership team. You’ll help structure, elevate and sell our strategic thinking, while staying close to the teams, the execution and the brands we work with.

You’ll play a central role in:

• elevating Socialsky’s strategic narrative and positioning, both internally and externally,
• leading high-stakes pitches and strategic conversations, guiding our clients and their brands to make smarter, social-first choices,
• infusing strategic thinking across the agency and your direct team, raising the overall level,
• positioning Socialsky as a reference in social-first communication.

This role is designed for someone who takes ownership naturally, but who also deeply believes in teamwork. No ego-driven solo players here. We win and learn together.

WHAT YOU’LL DO

Lead strategic thinking & new business

• Translate business and marketing challenges into clear, compelling, social-first strategies.
• Take the strategic lead on high-impact pitches and new business opportunities, especially for larger and more complex prospects.
• Structure and deliver strategic decks that convince clients and inspire, educate and elevate your direct team.
• Be involved early in key sales conversations, bringing depth, clarity and confidence to the table.

Turn “social-first” into a real, sellable methodology

• Help transform Socialsky’s intuition and expertise into structured and measurable strategic approaches.
• Strengthen the strategic layer behind content, trends, insights and data.
• Support the development of social-first systems combining content, influence, paid media and performance.
• Ensure that strategy is clear, intentional and rooted in reasoning. Not personal taste.

Infuse strategy across the agency

• Act as a strategic reference point for Account, Studio, Ads, Influence and Community teams.
• Help your direct team grow existing clients by identifying new strategic and business opportunities.
• Elevate the overall strategic maturity of the agency through collaboration, inspiration and hands-on involvement.

Represent and embody Socialsky

• Be one of the strategic faces of the agency at events, talks, conferences and industry moments.
• Actively strenghten Socialsky’s visibility and positioning, including thought leadership on platforms like LinkedIn.
• Support initiatives such as awards cases, new service launches and other strategic projects.

Be a trusted sparring partner

• Work closely with both CEOs in a dual-reporting setup.
• Be part of a growing leadership team and play an important role in shaping decisions that impact the present and future of the agency.
• Act as an entrepreunarial builder, not a spectator, in a company that’s still writing its story.

WHO YOU ARE

• A bright strategic mind and a doer: you connect big-picture thinking with hands-on execution.
• A passionate social-first thinker who truly understands platforms, trends, culture and audience behaviour.
• A natural storyteller, able to translate complex ideas into clear, convincing narratives.
• Autonomous by nature, yet deeply collaborative and team-oriented.
• A strong and confident presenter, equally comfortable guiding junior profiles and challenging C-level stakeholders.
• A builder at heart, energized by growth, structuring and creating things that last.
• Comfortable in a Gen Z-driven environment, understanding the codes, pace and expectations while bringing maturity and perspective.
• Someone with proven experience (min. 6 years) in strategic and commercial roles within an agency context.
• Native in French and/or Dutch, with good command of the other, and strong professional knowledge of English.

WHAT WE OFFER

• A key role in one of the most ambitious social media agencies in Belgium.
• Direct exposure to founders and leadership, with the opportunity to shape the future of an independent and entrepreneurial company.
• A fast-growing, performance-driven yet genuinely fun agency, without bullshit.
• A culture built on trust, ownership, transparency and team spirit.
• Competitive pay and perks, flexible work options, regular feedback and opportunities to learn and grow.
• Offices in Brussels and Antwerp, with an expected presence of 3 days per week onsite (including at least one day in Brussels). Our offices are modern, well-located and designed to make collaboration easy and enjoyable.
