Company mission
To empower women to feel confident in their day-to-day lives by providing them with great-fitting and comfortable underwear and bras.
Role
Who you are
- 5–7 years of hands-on experience in paid social, with a meaningful portion managing Meta Ads at scale (six-figure monthly budgets or above)
- Deep working knowledge of Meta Ads Manager — campaign structure, auction mechanics, creative testing, Advantage+ features, and attribution settings
- A genuine creative sensibility: you have strong opinions about what makes paid social work, and you can translate that into a brief or a feedback session
- Strong analytical fluency: you can build a performance narrative from raw data, not just pull a report
- Experience with or strong understanding of TikTok Ads — creative-first, algorithm-dependent, and very different from Meta in ways that matter
- Experience managing or coordinating external agency or vendor relationships, with accountability for their performance outcomes
- Cross-functional instincts: you have worked with creative teams, data teams, site teams, and external partners and found ways to move forward even when priorities differ
- An evaluative relationship with AI and automation tools — genuinely interested in their potential and willing to champion them, but equally willing to question the output, stress-test the logic, and push back when the results do not add up
Desirable
- Pinterest Ads experience — understanding of the platform's discovery-intent creative dynamics
- Experience managing or directing AI execution tools for paid channel execution
- Familiarity with MMM, MTA, or incrementality testing methodologies
- In-house DTC or e-commerce experience where you owned your channels with direct business accountability
What the job involves
- As the Growth Marketing Manager for Paid Social, you will own Meta, TikTok, and support on Pinterest from strategy through execution. You will oversee platform and agency relationships, direct AI tools for optimization, partner with internal teams on creative briefs and testing, and be the person who drives how we grow on these platforms
- You understand that winning on Meta requires both a data-driven and creatively-led approach. You treat Paid Social as a strategic function, take performance personally, have strong opinions about creative, and bring a genuine point of view to every channel decision
- Set the channel strategy for Meta, TikTok, and support on Pinterest including account and campaign architecture, funnel coverage, and budget allocation across each platform
- Own budget pacing across all three channels; make real-time reallocation decisions based on performance signals
- Lead incrementality test design for social channels in coordination with our measurement stack
- Contribute channel-level commentary to weekly cross-channel performance reporting
- Stay ahead of platform product changes, beta opportunities, and algorithm shifts on each platform
- Serve as the primary point of contact for all platform and agency relationships
- Manage day-to-day communication and performance accountability with any external partners on your channels
- Evaluate partner and vendor performance against clear outcomes; own the relationship and the decisions that come with it
- Consolidate institutional knowledge internally so that performance insights and channel history live with the team, not outside it
- Oversee and direct AI execution tools for bid management, audience optimization, pacing, and creative performance with curiosity about what they can do and healthy skepticism about when they are not working
- Interrogate automated optimization outputs: understand what the tool is doing, why it is making those decisions, and whether the logic actually serves the strategy
- Push back when AI-recommended actions do not hold up to scrutiny; override confidently and document what you learned
- Set guardrails, test protocols, and performance benchmarks that hold AI tools accountable to real outcomes, not just internal optimization metrics
- Lead AI tool evaluation with an analytical eye; you define the test and interpret the results
- Work closely with key stakeholders on creative brief direction — bring the performance signal and channel hypothesis to inform what gets made and why
- Bring a channel-native creative perspective to every brief: what works on Meta is not what works on TikTok; you know the difference and can articulate why
- Surface creative fatigue signals early and feed them into the brief cycle before performance degrades
- Collaborate on landing page testing by providing performance data and hypotheses on where the post-click experience is limiting paid efficiency
- Participate in creative QA before launch and contribute to post-launch performance interpretation
Our take
Many women know the discomfort of an ill-fitting bra, or the awkwardness of a bra-measuring session. To help with this, lingerie brand Thirdlove is doing things differently - by snubbing traditional sizing.
Thirdlove instead offers more than 80 bra sizes, including half-cups, to cater for women of any size or shape. In addition to building the brand to an impressive valuation, Thirdlove is on a social mission and has donated millions of dollars worth of bras to multiple charitable organizations.
The company remains a challenger to established apparel brands such as Victoria’s Secret, while also facing competition from other industry challengers including True&Co, Brayola and Lively. A move to sell a portion of its range through Amazon's marketplace should bring in additional customers for the brand and give it a boost in this competitive market.
