🚀 We're Hiring: PPC & SEM Campaign Manager Home Services | US Market | Full-Time | PST Hours

We're a performance-driven digital marketing agency specializing in home services and construction lead generation for the US market. We're looking for a hands-on Campaign Manager who owns results end to end — from strategy to the qualified phone call.

This is not a role for someone who only knows how to run ads. We need someone who understands the full journey: from search intent to phone call, from phone call to qualified opportunity, from opportunity to real revenue for a local service business.

⚠️ Non-Negotiable Requirements — Please Read Before Applying: → Full-time availability during US PST working hours 

→ Native-level English — written and verbal, non-negotiable 

→ Proven hands-on experience with the US market across Google, Meta, Bing, and native 

→ Solid, verifiable work history — not freelancers filling time between gigs 

→ Home services / construction experience required — e-commerce, SaaS, or fintech background alone is not enough

What you'll own: 

→ Plan, build, and manage paid campaigns across Google Ads, Meta, Microsoft/Bing, Taboola/Outbrain, Yelp Ads, Google Local Services Ads, and Nextdoor/LinkedIn as needed 

→ Create and optimize full-funnel lead generation strategies — audience targeting, ad copy, landing pages, tracking, and lead-nurturing funnels 

→ Monitor performance and continuously improve KPIs — cost per lead, lead quality, conversion rate, and ROI (not just clicks) → Own setup and integrity of conversion and call tracking so every lead is measured accurately 

→ Stay current on platform updates, A/B testing strategies, and market trends in home services 

→ Build repeatable systems, SOPs, reporting structures, QA processes, and campaign management workflows that allow the team to scale without losing quality 

→ Maintain strict QA discipline before every launch — budgets, geo-targeting, tracking, landing pages, phone numbers, forms, conversion actions, and campaign settings

AI & Automation — Core to This Role: 

→ Use AI to draft, test, and iterate ad copy and creative concepts at speed — with the judgment to edit and direct that output, never paste it raw 

→ Use AI for audience and keyword research, competitor analysis, and market intelligence 

→ Build reporting and analysis workflows that turn raw platform data into clear, decision-ready insights 

→ Be fluent in platform-native AI: Google Performance Max & Smart Bidding, Meta Advantage+, and AI-assisted creative — knowing when to trust automation and when to override it 

→ Build repeatable AI and automation systems using tools like Make.com, Zapier, or Google Apps Script to eliminate manual, repetitive work

Tracking & Attribution: 

✅ Hands-on with call tracking (CallRail or similar) and call-driven conversion measurement 

✅ Strong with GA4, Google Tag Manager, and conversion tracking across platforms 

✅ Familiar with offline conversion imports and server-side tracking to feed real lead quality back into platforms 

✅ You care what happens to a lead after the click — not just the cost of the click

Must-Haves: 

✅ Proven track record managing paid media campaigns targeting the US market 

✅ Deep knowledge of the home services vertical — remodeling, HVAC, solar, roofing, garage doors, windows, etc. 

✅ Demonstrated success generating high-quality leads at scale — measured by qualified leads and CPL, not vanity metrics 

✅ Experience building and managing end-to-end ad funnels from cold traffic to converted lead 

✅ Hands-on proficiency with Google Ads, Meta Ads Manager, Microsoft/Bing Ads, native platforms, and Google Tag Manager 

✅ Native-level English — strong written and verbal communication 

✅ Experience with Yelp Ads and Google Local Services Ads (LSA) — strong advantage 

✅ Familiarity with automation and lead-nurturing platforms — major plus

Who You Are: 

→ Independent, proactive, and execution-driven — you don't wait to be told what to do 

→ Data-minded but creative — constantly testing, iterating, and pushing performance boundaries 

→ You embrace AI and automation as tools for scale and smarter decisions — not as a gimmick or a crutch 

→ You think like a strategist and work like an operator 

→ You want to help small businesses grow — energized by making a real difference for an SMB owner, not by chasing the biggest budget

→ Loyal, analytical, hungry for results, and excited to grow as part of a small, sharp, accountable team

This role is NOT for you if: 

✖ Your background is primarily e-commerce/DTC, SaaS, or fintech 

✖ You rely on grey-hat or aggressive black-box agency tactics 

✖ You only want to direct strategy from above — we need someone hands-on, detail-oriented, willing to build, check, fix, test, and improve directly 

✖ You're a freelancer looking to fill time between gigs

Set up, run, and continuously optimise campaigns in Meta Ads and Google Ads. Key metrics: CPC, CPA, ROMI, ROAS, offline revenue, GMB-driven store traffic.

Navigating platform restrictions

Plan and run ads within Meta/Google policies for sensitive categories (cannabis, CBD, wellness). Work with CMO and legal to prevent bans and keep accounts healthy.

Creatives & hypothesis testing

Write briefs for designers, test offer × segment × format × placement combinations, and coordinate with brand and SMM teams.

Analytics & attribution

Configure GA4, pixels, UTMs, QR codes, promo codes, and offline conversions. Report monthly and quarterly on ROMI by channel, cost per store visit, and impact on new vs. repeat visits.

Requirements

- 3+ years in performance marketing / media buying with a focus on Meta Ads and Google Ads

- Proven experience with offline businesses — retail, HoReCa, clinics, fitness, wellness — where offline revenue matters as much as online leads

- Ability to build and optimise a full funnel — from impression to store visit and purchase

- Solid hands-on skills: Meta Ads Manager, Google Ads, GA4, basic GTM / event & conversion setup, Excel or Google Sheets (pivot tables, basic analytics)

- Comfortable working under platform restrictions — you don't burn out every time an ad gets rejected

- English Upper-Intermediate or higher (platform interfaces, support, working with English-language creatives and audiences)
