Senior Talent Acquisition Partner

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.

The Role

We’re looking for an experienced Talent Acquisition Partner to take ownership of hiring during one of Flux’s most critical periods of growth. We’re scaling rapidly across software, hardware, optics, commercial, and operations, and hiring is our #1 priority.

You’ll work directly with leadership, hiring managers, and the People and Operations teams to drive top-of-funnel strategy, candidate experience, and the hiring process end to end. You’ll own both delivery and systems, jumping in to personally close hard-to-fill roles, while building the infrastructure that helps us hire smarter and faster. This role is based in our Kings Cross, London office and is 5 days a week in person.

Responsibilities

• Own full-cycle recruiting across key roles (engineering, technical leadership, operations, commercial), from sourcing through to close.
• Build and execute scalable sourcing strategies to surface top-tier, hard-to-reach candidates across the UK, EU, and US.
• Partner with hiring managers to craft compelling roles, sharpen their interviewing skills, and ensure fast, high-quality processes.
• Set and uphold high standards for candidate experience; every touchpoint should reflect our values.
• Help define and drive Flux’s employer brand, ensuring we show up in the right communities with the right voice.
• Own and evolve the recruiting stack and reporting.
• Identify and implement process improvements as we scale (e.g. calibration tools, interview training, DEI tracking).
• Lead our relationships with external partners (agencies, sourcers, etc.) and hold them to a high bar.

Skills & Experience

• Substantial experience (7+ years) of recruiting experience, at least half of which has been in-house at a fast-paced startup or high-growth tech company.
• Track record of hiring top technical talent, whether that’s ML engineers, digital designers, systems architects, or otherwise.
• Excellent sourcing instincts and a creative approach to candidate engagement.
• Confident advising and influencing senior stakeholders; you’re comfortable saying “no” and backing it up with data or insight.
• Organised, responsive, and rigorous; you keep processes moving without dropping the ball.
• Passionate about candidate experience and helping build a hiring culture that scales and drives forward the company values.

Nice to have:

• Experience in deep tech or hardware-driven environments, especially where talent is scarce and highly specialised.
• Comfort with analytics and storytelling using pipeline data to inform strategy.

This is a rare opportunity for someone with the right mix of ownership, urgency, and precision. But it’s not for everyone. You will thrive here if you:

• See the strategic advantage that working side-by-side in an office can bring. We’re building fast, and proximity matters.
• Are excited to set aside the playbook in favour of deeply customised, high-signal hiring practices. You want to build what most people haven’t.
• Champion transparency, rigour, and pace. You believe in building a hiring culture that’s deeply collaborative and performance-driven to set the right tone for new joiners from their first interaction.
• Use ChatGPT multiple times a day. We’re scaling responsibly, and that means using AI as a starting point, a coach, and a constant amplifier of our work.

Details

• Competitive salary ranging from £81k-102k, 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
• To foster collaboration in our high-growth environment, we require all employees to work from our London HQ and live within a 45-minute commute. We 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

If you’re excited by the idea of growing the team that is building the infrastructure for AGI, and want to do it fast, well, and with zero tolerance for fluff, we’d love to hear from you. Join us as our Senior Talent Acquisition Partner and help shape the company from the inside out.
