## Job description

Labhouse is a fast-growing startup that builds, launches, and scales its own AI & Productivity Apps, operating under a subscription-based business model.

Based in Barcelona, Labhouse was founded by Andrés Bou and Horacio Martos (Co-Founders of SocialPoint).

We operate at the intersection of mobile technology, AI, and product-driven growth, with a strong focus on experimentation and performance.

Would you like to make an impact as part of a company that builds the best mobile apps used by millions of users worldwide? If so, discover your next challenge below.

## ABOUT THE ROLE:

We are looking for a SEM Lead or Senior SEM Expert to lead and scale our paid search strategy across our portfolio of apps.

This is not a campaign management role. This is a technical, strategic, and revenue-driven position where Google Ads Search is the absolute core of the function.

You will be the reference person for Search inside the company, owning:

- Campaign architecture
- Budget allocation
- Profitability logic
- Scaling frameworks
- Signal quality & algorithm performance

Your mission is simple: maximize revenue and efficiency from Google Search while building scalable and technically robust acquisition systems.

## ABOUT YOU:

## ACADEMIC BACKGROUND:

- Bachelor’s degree in Marketing, Business, Economics or related fields.
- Technical background in Engineering, Data Science, Mathematics or similar quantitative disciplines is highly valued.
- Strong analytical foundation with the ability to build dashboards, scripts, and data queries independently.

## TECHNICAL EXPERTISE:

- Deep, hands-on expertise in Google Ads Search (must-have).
- Strong knowledge of campaign architecture, keyword intent segmentation, match types, search term mining, and negative keyword frameworks.
- Experience designing scalable account structures from scratch.
- Solid understanding of Smart Bidding, conversion signals, tracking, and attribution.
- Ability to evaluate performance based on business metrics (CAC, LTV, revenue impact), not only CPC/CTR.
- Comfortable building dashboards, automations, scripts, or working directly with raw data (GA4, Looker Studio, BigQuery or similar).

## PROBLEM-SOLVING AND PRODUCT FOCUS:

- Excellent problem-solving and analytical skills, with the ability to resolve complex performance challenges.
- Strong business mindset — prioritizes profitability and unit economics over vanity metrics.
- Structured optimization approach (bid increases are not the first lever).
- Eye for detail and scalable systems thinking.
- Self-driven, entrepreneurial attitude with full ownership mentality over the Search channel.

## COMMUNICATION:

- Good level of spoken and written English.
- Ability to collaborate effectively with Product, Data, and Marketing teams.
- Capable of clearly explaining performance insights and strategic decisions.

## NICE TO HAVE:

- Experience with Google Display Network.
- Experience with YouTube Ads.
- Experience in app environments or multi-product portfolios.

## WHAT WE OFFER:

- Remote work from anywhere in Europe. If you are based in Barcelona, we would love for you to join us at the office (Barcelona Tech City) at least two days a week.
- Flexible working hours.
- Competitive compensation
- High-end equipment for your development.
- Permanent contract with competitive compensation.
- A young and top entrepreneurial team in a dynamic startup environment.
- Opportunity to lead, grow, and take on big challenges.
- Work with cutting-edge technologies, including the chance to integrate AI models into new apps.

## YOU SHOULD KNOW:

Labhouse is proud to be an equal-opportunity employer. However you identify or whatever your journey to this point, we welcome all candidates to apply for the position that inspires them.

Come join us and help us build a company that everyone is proud to be part of.

## Competitive Advantages
- **Studio model**: One integrated team across product, design, engineering, AI, and growth — enabling faster shipping and tighter feedback loops compared to siloed organizations.

## Strategic Focus
- Continuing to scale existing apps (Cleaner GO, Invoice Fly, Summary AI) in Tier-1 and long-tail Asian markets.
- Building new AI-native mobile experiences through rapid prototyping (four-phase sprint: Concept → Build → Launch → Scale).
- Deepening monetization through subscription models and internationalization.
- Hiring aggressively for AI, engineering, and growth roles to support expansion. [jobs.ashbyhq.com/labhouse](https://jobs.ashbyhq.com/labhouse)

- **Builders, not pointers**: Emphasis on hands-on builders who care about craft, not managers who delegate. [labhouse.io](https://labhouse.io/)

- **Impact at scale**: Products used by millions daily across 50+ countries; chance to work on apps with proven traction.
- **Culture**: Described as "a small team of curious minds, obsessive product builders, and action-oriented problem solvers" who believe productivity software is "never finished." [labhouse.io](https://labhouse.io/)
