Talent Sourcer

Company Overview

Flux is pioneering a new class of AI accelerators called Optical Tensor Processing Units (OTPUs). Our work environment rewards innovation, speed, and bold thinking.

We’re looking for a Talent Sourcer to build and fuel the top of the hiring funnel during one of Flux’s most critical periods of growth. We’re scaling from 25 to 90+ people in the next 6 months across software, hardware, optics, commercial, and operations.

You’ll work closely with leadership, hiring managers, and the People & Operations teams to identify, engage, and activate exceptional talent across multiple hard-to-hire disciplines. You’ll be responsible for designing sourcing strategies, developing market intelligence, and delivering a steady stream of qualified candidates who convert into hires. You’ll also help build the systems, tools, and best practices that allow us to source smarter and faster as we scale.

This role is based in our Kings Cross, London office and is 5 days a week in person.

• Own top-of-funnel sourcing across priority roles (engineering, technical leadership, operations, commercial), ensuring a consistent pipeline of high-calibre candidates.
• Build and execute creative, scalable sourcing strategies across the globe, including outbound campaigns, talent mapping, community engagement, and referrals.
• Conduct first-touch candidate assessments to ensure strong alignment before handing over to recruiters.
• Partner with hiring managers to understand role requirements, ideal profiles, and market realities; advise on strategy and expectations.
• Uphold best-in-class candidate engagement; your outreach and communication should reflect our values and set the tone for the full hiring journey.
• Build and maintain talent pools for repeat or future hiring needs, ensuring we’re never starting from zero.
• Contribute to employer branding initiatives by identifying where top talent spends time and shaping how we show up in those communities.
• Help refine sourcing processes, tooling, and reporting to scale with the business. Manage relationships with external sourcing partners and ensure they deliver consistently high-quality output.

• 5+ years of sourcing experience, ideally within high-growth tech, deep tech, or hardware-centric environments.
• Demonstrated success sourcing top technical talent: ML engineers, digital designers, systems architects, or similarly specialised profiles.
• Strong sourcing instincts and fluency with modern tools, boolean strategies, and creative research methods.
• Confident partnering with senior stakeholders and translating ambiguous requirements into clear, actionable sourcing plans.
• Highly organised and responsive; maintain clean data, tight loops, and predictable output.
• Passionate about building exceptional candidate experiences from the very first touchpoint.

• Experience in deep tech or hardware-driven environments, especially where talent is scarce and highly specialised.

• See the strategic advantage that working side-by-side in an office can bring. Proximity matters.
• Excited to set aside the playbook in favour of deeply customised, high-signal hiring practices. Want to build what most people haven’t.
• Use ChatGPT multiple times a day. Scale responsibly, using AI as a starting point, a coach, and a constant amplifier.
• Champion transparency, rigour, and pace. Build a hiring culture that’s deeply collaborative and performance-driven.

• Competitive salary ranging from £60-85k, depending on experience.
• Generous stock options in a rapidly growing AI company.
• Based in our new 5,000 sq. ft. office in the AI hub of Kings Cross, London.
• Require all employees to work from our London HQ and live within a 45-minute commute. Offer an extra £24,000/year incentive for those living within 20 minutes.
• Comprehensive healthcare insurance.
• 25 days PTO policy plus bank holidays.
• Private access to our in-house 3D printer.
