Head of Marketing

Overview

Sigma Squared is hiring a Head of Marketing to serve as the first full-time member of our marketing organization. You will own the full marketing stack from day one: product marketing, demand generation, branding, PLG & ABM, analytics, and content. You’ll set the strategic direction and personally execute across every channel while building a world-class team around you as we scale. Looking for someone equally comfortable presenting market positioning to the executive team as they are spending an afternoon in HubSpot tuning a nurture sequence.

Key Responsibilities

Go-to-Market Strategy & Positioning

• Own and continuously refine the company’s go-to-market strategy, ensuring marketing directly accelerates pipeline and revenue.

• Define Sigma Squared’s category position and craft differentiated messaging that sets us apart in a competitive market.

• Research, build, and iterate on the Ideal Customer Profile (ICP); identifying the buyers, segments, and use cases where we consistently win.

• Serve as a strategic partner to the executive team and, as the company matures, to the board on market positioning, competitive intelligence, and product roadmap input.

• Work hand-in-hand with Sales, Product, and Customer Success to align messaging, close feedback loops, and support the full customer journey from awareness through expansion.

Demand Generation & Pipeline Building

• Build and execute a multi-channel demand generation program (email, paid search, paid social, content, webinars, events) designed to consistently hit MQL, SQL, and marketing-generated pipeline targets across SMB, mid-market, and enterprise segments.

• Design and run structured A/B testing across ad formats, audience targeting, landing pages, email subject lines, body copy, and CTAs.

• Own LinkedIn and other paid social campaigns with a relentless focus on cost efficiency; manage suppression lists, target account lists, and audience segmentation on an ongoing basis.

• Build out HubSpot workflows, lead scoring, nurture sequences, and CRM hygiene practices to ensure clean attribution and reliable reporting from day one.

• Track and report on marketing’s contribution to pipeline.

Product-Led Growth (PLG) & Account-Based Marketing (ABM)

• Run both PLG and ABM motions simultaneously—acquiring and converting self-serve users while orchestrating targeted, high-touch plays for enterprise accounts.

• Build low-cost, high-converting campaign programs that drive product adoption and surface expansion opportunities within the existing customer base.

• Collaborate with Product and Customer Success on in-product messaging, onboarding flows, and activation metrics that reduce time-to-value.

• Develop and maintain target account lists and tiered ABM programs that align marketing investment with the highest-value opportunities in the pipeline.

Brand, Messaging & Content

• Own Sigma Squared’s brand voice, visual identity guidelines, and messaging architecture across every external touchpoint.

• Write and edit high-quality content; blog posts, case studies, email & social campaigns, sales collateral, website copy, etc.

• Manage the website as a conversion asset: messaging, SEO, CRO, and landing page performance are all within your remit.

• Develop sales enablement materials (decks, one-pagers, email templates, etc.) that help the sales team tell a compelling, consistent story.

Marketing Operations & Analytics

• Serve as the primary owner of the marketing tech stack; evaluate, implement, and optimize tools with a focus on performance and scalability.

• Build and maintain analytics dashboards that give leadership clear, real-time visibility into marketing performance and spend efficiency.

• Manage the marketing budget with a performance-first mindset, making data-driven decisions about where to allocate and where to cut.

• Lead or inform platform migrations when the existing stack isn’t serving the business (e.g., evaluating a move from legacy tools to HubSpot Marketing Hub and CMS).

Team Building & Leadership

• Operate as a solo marketing leader initially, with the authority and mandate to hire thoughtfully as pipeline and revenue justify headcount.

• Define the structure of the marketing function you want to build, and recruit accordingly.

• Manage agency relationships, freelancers, and contractors to extend execution capacity in the short term.

• Model a high-performance, data-driven marketing culture from the start.

Qualifications

• 7 years of B2B marketing experience, preferably in SaaS but broader tech domain experience is welcomed.

• A genuine builder mentality, having either been the first marketer before or excited about working in a lean, high-ownership environment.

• Developed brand positioning and messaging in a competitive or emerging category, comfortable with market education.

• Conducted ICP research from scratch: customer interviews, firmographic analysis, win/loss reviews, and translating findings into actionable targeting.

• Driven measurable cost-per-MQL reduction through disciplined A/B testing via LinkedIn, paid search, email, etc.

• Launched or scaled a product-led growth motion via low-touch, self-serve acquisition with measurable activation and conversion metrics.

• Implemented and owned martech stack and automation tools; CRM, workflows, lead scoring, sequences, attribution, and reporting.

• Built marketing dashboards using BI tools (Looker, Tableau, etc.), SQL, or Python that track pipeline contribution, channel efficiency, and MQL quality.

• Written marketing copy for long-form content, email, social, website, sales enablement, etc.

What We Offer

• A uniquely compelling opportunity to advance our mission with world-class colleagues, a tremendous amount of responsibility and autonomy, and access to all the information you need to succeed.

• Comprehensive health, dental, vision, and FSA/HSA benefits.
