Sales Development Representative (SDR)

About Kernel

Kernel gives enterprise RevOps teams confidence in their CRM data.

We’ve raised a $14M Series A from top VCs and operators at Plaid, OpenAI, Slack and others to build the AI-native alternative to Dun & Bradstreet’s entity and hierarchy data.

RevOps teams at Gong, Navan, Zip, Remote and GoCardless use Kernel to clean, enrich and complete their CRM data at enterprise scale, eliminating duplicates, fixing hierarchies and restoring trust in the foundation that powers forecasting, territory planning and AI initiatives.

Our platform combines entity-level intelligence with mass-action tooling to give RevOps teams the data quality and control needed to plan confidently and deploy AI successfully.

The Role

We’re looking for someone to join us in Sales Development to own a book of pre-tiered accounts. Your primary mission is to generate qualified pipeline by researching, prospecting, and engaging the right companies and stakeholders.

You’ll spend most of your time leveraging Kernel’s data-driven insights to develop hyper-targeted outreach — primarily via calls (80–95% of pipeline for B2B companies comes from calling) — as well as LinkedIn DMs and other channels.

You’ll partner closely with Marketing and AEs, but your day-to-day will focus on building research-led, phone-first cadences that convert.

What You’ll Be Doing

• Identify and research high-fit companies and decision-makers using Kernel’s data

• Build and maintain a consistently updated target list with clear qualification criteria

• Execute a phone-driven cadence (cold calls + voicemails) to generate meetings

• Use insights like funding, hiring, or tech stack to personalize outreach

• Mix LinkedIn, email, and phone in multi-touch cadences

• Book qualified meetings for AEs and provide detailed call notes

• Collaborate with Marketing to refine ICPs and messaging based on feedback

• Iterate on messaging and cadences based on performance

• Share field feedback to inform product and GTM strategy

What You Bring

• 1–4 years of B2B sales or SDR experience in a high-growth environment

• Proven success hitting or exceeding activity and pipeline targets

• Strong verbal and written communication skills

• Comfort with data-driven outreach and using tools like Salesforce or LinkedIn Sales Navigator

• Research-oriented mindset — you like understanding the “why now” behind prospects

• Entrepreneurial and proactive attitude; comfortable owning results

Nice to have:

• Familiarity with tools like Outreach, Gong, or ZoomInfo

• Startup experience or exposure to early-stage GTM motion

• Interest in AI, data, or automation

⚠️ This role may not be for you if you:

• Prefer slow-paced, highly structured sales environments

• Avoid cold calling or phone-heavy work

• Need rigid scripts instead of conversational selling

❌ This role is definitely not for you if you:

• Prefer remote work (requires 4+ days a week in the London office)

• Don’t enjoy the intensity of early-stage GTM

• Have side hustles or other projects that split focus

What We Offer

We will do our best to offer you a ride of a lifetime. It will not be easy, but it will be thrilling.

• 💰 Salary: £40,000 – £70,000 + equity

• 🗓️ 24 days holiday per year + bank holidays

• 💼 Pension plan

• 💻 Top-spec equipment and central London office

• 🍽️ Free dinner at the office

• 🎉 Team events and dinners

• 🚀 Work directly with the founders to scale the systems that power enterprise AI
