At Byld, Marketing is not a support function. We are creating something new, so we need to be heard, we need to be listened to, and most importantly, we need to be understood.

As Senior Marketing & Communications Specialist, you will be one of the key owners of Byld’s external voice and internal brand excellence. Your mission goes beyond “branding”: you will help turn marketing into a lever for lead generation—by driving engagement and demand creation (nurturing, authority-building, and stronger conversion to qualified pipeline)—while elevating our thought leadership in corporate venture building and innovation.

You will work hand-in-hand with colleagues specialized in Business, Growth and Business Development, and collaborate closely with Growth, Building, Talent/People and the rest of the company circles. This work dynamic creates synergies where everyone can learn from different fields and disciplines—and where marketing directly impacts business outcomes.

As a Senior Marketing & Communications Specialist, you will gain hands-on experience in Venture Building while owning key marketing outcomes. Throughout your journey, you will:

Establish and execute people-centric brand and communication strategies that position Byld as a top-of-mind reference in Corporate Venture Building, Strategy & Innovation, translating complex expertise into clear, compelling narratives.
Uncover audience and stakeholder needs (corporates, ecosystem players, talent, partners) through research and active listening, transforming insights into messaging, content angles and campaigns that drive awareness and demand.
Design, build and continuously improve high-quality marketing assets (content, campaigns, narratives, landing pages, newsletters, event storytelling) to strengthen authority, accelerate trust and generate qualified opportunities.
Unleash the power of growth thinking by combining organic and paid distribution (especially LinkedIn) to test hypotheses, learn fast, and systematize a pipeline of qualified leads (MQLs) through web + content.
Pivot as often as the data requires: iterate messaging, channels and formats with frugality and speed—aiming for “less but better”, and making quality and clarity non-negotiable.

What we are looking for…

Have 3–4 years of work experience in Marketing / Communications / PR / Content roles in startup/fast-paced environments, consulting, innovation ecosystems, or similar.
Have experience producing and editing excellent content in Spanish and English (copywriting, storytelling, scripts, articles, newsletters, campaign messaging), with strong attention to detail (“zero defects”).
Be comfortable collaborating cross-functionally (Growth, Business, Product, People, Building) and managing multiple initiatives in parallel without losing quality.
Enjoy being in events and have strong social skills: comfortable networking, representing Byld in the ecosystem, and supporting the organization of our internal events.
Have experience with PR, events, and ecosystem building: comfortable collaborating with partners and ecosystem players (startups, corporates, investors, media), and turning relationships + moments into brand authority and business opportunities.
You have experience organizing events and/or building community initiatives (internal and external), and you genuinely enjoy showing up where the ecosystem is happening.
You’re comfortable with metrics and performance: you like working with data, funnels and learning loops (web, social, newsletter, campaign performance) and you use insights to improve decisions.

…but the most important characteristics are as follows:

You have a user-centric lover approach/mindset, endlessly curious, with a strong interest in social, tech, and cultural trends, and a passion for building narratives that resonate.
You are a fan of metrics and analytically driven data: you measure, you learn, you iterate.

We will roll out the red carpet for you if (not a must):

You hold strong analytical and problem-solving skills and you can make decisions with controlled uncertainty.
You obsess over quality and brand consistency: you protect the brand and elevate the bar of every deliverable ("zero defects").
You are comfortable with no-code tools and are used to applying them on a daily basis: Framer (big plus), Figma, Notion, and AI tools - any toolkit you can bring to the table is more than welcome.

What we look for in anyone at Byld…

You know and are curious about new technologies and innovation and their impact on the world that we live in.
Controlled uncertainty is something that you feel comfortable with.
You are able to multitask and work in rapidly changing environments.
Your attitude is dynamic, ambitious, and you are eager to learn.
You are able to confront opposing opinions.
You are willing to take risks, take initiative, and say what you think at every moment.
You are obsessed with quality.
You have read our values and you identify with them.

This allows corporations to properly confront the fierce competence of startups and other rivals and adapt to the constant change of present times, transforming opportunities and tendencies into new disrupting businesses.

Ultimately, this is achieved thanks to the combination of the dynamism, versatility and culture behind the startups mindset that we bring to the table and the resources, outreach and experience of the big corporations that we partner with.
