Full Stack Marketer, Horizontals

The Opportunity

Firstsource is hiring a Full Stack Marketer to own the horizontal marketing programme across all service lines. This is a high-ownership, end-to-end individual contributor role, not a support function.

Horizontal means your work spans Firstsource’s full portfolio: Artificial Intelligence, Collections, Consulting, Customer Experience, AI-First Marketing, Digital Platforms & Technologies, IT Services & Solutions, Trust & Safety, and more. You sit alongside horizontal business and marketing leadership, translate growth priorities into a campaign-ready GTM plan, and execute it end-to-end.

Your primary mandate is digital marketing: designing, launching, and optimizing campaigns that drive qualified pipeline and measurable revenue. Specialist teams for events, inside sales, marketing operations, and technology support you — but you are the one who connects strategy to tactics, tactics to pipeline, and pipeline to revenue.

What You Will Own

Digital Campaign Strategy & Execution

• Design, build, and run integrated digital campaigns from brief to deployment — including content marketing, email sequences, paid media, social amplification, webinars, and podcasts
• Own the full campaign lifecycle: audience definition, messaging, channel selection, creative production, launch, optimization, and post-campaign analysis
• Use data to decide what to run, what to kill, and where to double down — you know the right questions to ask before the dashboard tells you anything
• Produce compelling content — white papers, thought leadership, sales collateral, email nurture sequences, and social copy — with a strong editorial eye; you can write a persuasive white paper and a tight subject line from the same brief
• Understand and execute ABM: 1:1, 1:few, and 1:many campaigns across existing and new accounts to land and accelerate revenue

GTM Planning & Revenue Accountability

• Partner with horizontal marketing and business leadership to convert strategy into a concrete GTM plan with clear ICP, messaging, channels, and pipeline targets
• Own marketing-sourced and marketing-influenced pipeline for horizontals — measured in opportunities created and revenue influenced, not activity volume
• Track funnel conversion metrics (MQL → SQL → SAL), pipeline coverage, cost per qualified lead, and marketing-influenced win rate
• Conduct gap analysis across value proposition, competitive positioning, demand signals, and industry trends to inform quarterly priorities

Strategic Content Development

• Own the horizontal content calendar: planning, commissioning, and producing long-form and short-form assets aligned to business objectives and GTM priorities across all service lines
• Translate Firstsource’s positioning — Intelligence that Operates, domain expertise, outcomes-based delivery — into compelling narratives for C-suite and senior practitioner audiences
• Define content personas, buying-stage content maps, and topic clusters for horizontal themes: AI adoption, agentic operations, digital transformation, and business outcomes
• Develop and execute content with SEO best practices built in: keyword strategy, topic clustering, internal linking, metadata, and structured content for AI Overviews and answer engine optimisation
• Maintain and evolve the Firstsource content hub: taxonomy, discoverability, and SEO architecture

AI-Enhanced Research & Production

• Actively use AI tools (Claude, ChatGPT, Perplexity, and equivalents) across your daily workflow — for content production, research, personalisation, and campaign iteration at 3–5x traditional velocity
• Synthesise complex information — analyst reports, SME conversations, primary research — into clear, authoritative narratives that demonstrate genuine expertise
• Accelerate campaign production using Firstsource’s AI platforms and custom agents, reducing dependency on agencies and specialist queues
• Stay current on AI developments relevant to Firstsource’s service lines and translate that knowledge into timely, credible content

Supporting Responsibilities

You will coordinate with and be supported by specialist teams in the following areas:

• Event Planning: Brief the Events team on horizontal-specific event strategy; ensure events feed pipeline
• Inside Sales Coordination: Align campaign follow-up sequences with the Inside Sales team to maximise lead conversion
• Marketing Technology: Work with MarTech and Data Analytics for reporting, attribution, and platform support; you are a power user, not the administrator
• Brand & Ecosystem: Ensure horizontal communications are on-brand; activate partner and alliance marketing to amplify reach; coordinate with Brand and Corporate Marketing for alignment
• Design: Collaborate on visually compelling assets: infographics, report covers, social creative
• Legal & Compliance: Partner on approval of client-facing materials

What We Are Looking For

Strategy-to-Revenue Thinking — You take a business objective, translate it into a marketing strategy, decompose it into campaigns and tactics, and trace the outcome back to pipeline and revenue. You think in funnels, not just formats.

End-to-End Marketing Execution — You have personally built and run multi-channel campaigns — not just briefed them to a team. From audience targeting through creative production to performance analysis, you have done the work.

Content as a Growth Lever — You know how content fits into a demand generation system. You can brief, produce, and commission assets that serve campaign and pipeline objectives — and you have the editorial judgement to ensure quality without being the bottleneck.

Data-Driven Decision Making — You are fluent with marketing analytics. You know which questions to ask the data before pulling a dashboard. You make investment decisions based on ROI, attribution, and pipeline coverage — not gut feel.

AI-First Mindset — You actively use AI in your daily workflow for content production, research, personalisation, and campaign iteration. This is not a checkbox; it is how you work. You will be enabled with Firstsource’s AI platforms and agents to accelerate your impact.

Industry Acumen — You understand B2B professional services well enough to develop relevant messaging, target ICPs, and create compelling campaigns across services ranging from AI and digital platforms to collections and customer experience.

Cross-Functional Partnership — You have operated in a matrix environment — working across marketing leadership, business unit leaders, sales, solutioning, and external partners simultaneously.

Required Qualifications

• Experience: 5+ years of B2B marketing experience in services, technology, or SaaS — with a track record of owning pipeline generation, not just content production
• Campaign Execution: Minimum 3 years in a digital marketing, growth marketing, or full-stack marketing role where you personally built and ran multi-channel campaigns end-to-end — audience targeting, creative, launch, optimisation, and reporting
• Industry Background: Marketing experience in IT/ITES, BPS, SaaS, or professional services — with enough domain fluency to develop credible messaging without needing to be briefed on every concept
• GTM & ABM: Demonstrated ability to translate business strategy into a GTM plan with clear ICP, messaging hierarchy, channel mix, and pipeline targets; hands-on ABM execution across 1:1, 1:few, and 1:many programmes
• Data Fluency: Comfortable with funnel metrics (MQL → SQL → SAL), pipeline attribution, cost per qualified lead, and marketing-influenced win rate; able to make investment decisions from data, not intuition
• AI-First Proficiency: Hands-on, daily use of AI tools (Claude, ChatGPT, Perplexity, or equivalents) for content production, research, personalization, and campaign iteration — not experimental familiarity
• Marketing Platforms: Strong working knowledge of HubSpot, Salesforce CRM, Demandbase or similar ABM tools, and analytics/attribution platforms
• Education: Bachelor’s degree in business, Marketing, Communications, or a related field
