Part-time Social Media Manager

Hi there

We're Phira Ventures - a Lisbon- and New York–based venture studio partnering with exceptional talent to build companies that deliver real impact.

Right now, we're hiring a Part-Time Social Media Manager to help build world-class social presences for Phira and our portfolio companies across multiple industries.

You will be in charge of the social media profiles across several brands: strategy, content, posting, community, and performance.

This role is for someone who genuinely lives social. You have a deep understanding of working with the algorithms of platforms like Instagram and TikTok, understand trends early, know what hooks attention, and how to create a viral post.

You'll work closely with founders and small, high-output teams. You'll get real responsibility from day one, and will have a steep learning curve. The role starts part-time and can evolve into a full-time position for the right person.

Heads-up: This role is not for everyone. Don't think you'll post a couple of stories and are done for the day. At Phira, this is your department, and you are responsible for its success. This is a dream opportunity for someone who loves spending time on social media and wants to make this their job.

• Own Social Across Brands: Manage social media for Phira and multiple portfolio companies across different verticals.
• Create High-Performing Content: Ideate, produce, and publish content tailored to each brand that drives reach, engagement, and follower growth.
• Trend & Algorithm Mastery: Stay ahead of trends and platform shifts, and translate them into content formats that win.
• Branding & Aesthetics: Maintain a strong visual standard across posts, stories, reels, and profiles. Keep feeds clean, consistent, and on-brand.
• Content Systems: Build a practical content calendar and workflow to ensure consistent execution across multiple brands.
• Collaboration with the marketing team: Work on what matters and moves the needle.
• Community & Engagement: Manage comments and DMs, foster community, and elevate the brand voice.
• Performance & Iteration: Track what performs, learn fast, and iterate. Build a repeatable loop of testing hooks, formats, and narratives.

You will thrive here if you…

• Have a proven track record of excellence (work, side projects, creator accounts, viral posts, standout campaigns, personal achievements).
• Live social media: you understand trends, formats, and platform mechanics deeply (especially short-form video).
• Have taste: strong eye for aesthetics, branding, and what looks premium.
• Have creator instincts: you can write hooks, structure posts, and package ideas in a way that people actually share.
• Are highly reliable: you organize yourself flawlessly, hit deadlines, and manage multiple workstreams without chaos.
• Are low-ego, fast-learning, and comfortable with feedback.
• Communicate crisply in English.

• You've had viral content before (show us).
• You can do lightweight editing (CapCut/Premiere) and basic design (Canva/Figma).
• Experience running social for startups, creators, or consumer brands.
• Basic analytics fluency: you know what to track and how to adjust content accordingly.

• High variety, high learning: you'll work across multiple brands, industries, and audiences.
• Ownership from day one: direct line to founders and meaningful responsibility.
• Part-time with a path to full-time for the right person.
• Tax support: the company covers accountant fees, filing tax returns, and related services.
• Pet-friendly office (yes, we have an office dog).
• Free access to the world-class products & services we build at Phira.
• Regular & exciting team events across the Phira portfolio.
