Steve Walker
Managing Director
"Necessity is the mother of all invention".   I set up S3 21 years ago. One recruitment sector led to another, with all that I learned about the pitfalls, problems and lack of opportunity for people trying to start their career working in Life Science, pushing and developing both myself and my team.   Back in 2002, S3 was just one of a handful of organisations actively promoting Life Sciences recruitment to the wider public and within the scientific community.   Fast forward to today, and we now open ALL the doors for job seekers looking to work in a rewarding career. We are proud to embrace inclusively and diversity in the workplace.   As the business's founder, I’m lucky enough to work with several talented & like-minded individuals. If we can help you with any aspect of recruitment, career progression or just to discuss why you can't seem to attract the right candidates - get in touch.   I’m a proactive networker and a great listener & fortunately, I love a challenge. If I can help you directly, I will. If I can’t, I’ll probably know someone in my team who can.   Thanks for reading, Steve

Alex Black
Recruitment Director
Before joining S3 Science, I worked in Education Recruitment in London, recruiting teachers across the capital. This was the beginning of a new chapter after leaving school early to pursue a career, which stimulated and intrigued me. I then had the opportunity to join S3 Science and go into a completely different industry that is making a huge difference. I jumped at the chance and love every minute of what I do. I am an avid West Ham supporter, which involves a lot of heartache and frustration. I put myself through the pain of watching them on a weekly basis! Ever since joining S3 Science, I haven’t looked back. The opportunity to work in an industry that is out fighting cancer is a very rewarding experience, one of which I am proud to be a part of. I love telling people about the industry and the amazing work that goes on. My role at S3 Science is as a Recruitment Consultant. I specialise in finding the best Life Science professionals out there for roles with clients across the UK. I offer advice on getting into the industry and the amazing career progression available.

Finance Manager
Prior to joining S3 Science, I worked as a bookkeeper within the Insurance industry whilst gaining my accounting qualifications. My role within S3 Science is that of Finance Manager. I look after the start-to-finish process within the company while also looking at all the new governmental guidelines that come out. Outside of work: I’m a keen gardener and allotment keeper and try to grow and preserve all my own fruit and vegetables for the year; I’m also the owner of various animals that I love and enjoy cooking and baking.

Hannah Schembri
Recruitment Consultant
Before joining S3 Science, I trained at Graham Webb International as a Hairstylist.  After training for 3 years and with the COVID-19 pandemic, I felt the time was right for a career change. I wanted to do something worthwhile, and that made me feel good. With training, I have been successfully promoted from a Trainee Candidate Recruiter to a fully-fledged Recruitment Consultant, and I am absolutely loving my work! My role is to work alongside companies and candidates to identify the right talent for each organisation successfully.  I work closely with my candidates by getting to know them, understanding what they are looking for and aim to facilitate their dream move! I do this by working with my clients to identify their recruitment needs that will help their teams excel. I’m here to help make the recruitment process as easy as possible. I take so much pride from the industry I work in, being part of the Life Sciences industry means I can be involved in identifying the talent that makes a real difference in saving lives. I get to work with fantastic organisations that are at the forefront of research against horrible diseases such as Cancer, Alzheimer’s and diabetes, to name a few.

Kai Tickner
Recruitment Consultant
Hello, I’m Kai. I work as a Recruitment Consultant here at S3. It’s my job to help both candidates find their dream roles and clients find their next superstar! I started at S3 back in 2021 and have been learning the ropes of recruitment, learning my craft as a Candidate Recruitment Consultant and then progressing to a Recruitment Consultant - where I manage and consult with my own respected clients. Outside of work, I’m passionate about music and sports; I regularly attend venues and events with live acts playing. In terms of sports, I am a massive combat sports fan of both boxing and MMA, as well as a passionate supporter of Chelsea FC (Champions of Europe). Feel free to contact me for any recruitment-related questions.

Marcie Porter
Recruitment Consultant
Before joining S3, I trained as a Primary School Teacher; I wanted a change in my career. Recruitment interested me as I knew I could help people find their dream job. Since being with S3, I have learned that it is an extremely rewarding role where I can better people’s lives. It is a joy of mine to speak to different candidates and clients every day and build great relationships. The industry we work in is something that really interests me, and I have learned and developed my knowledge since being here. I never considered recruitment as a career before, but now I never look back. It is the only job that has pushed me to my limits and believed in me to succeed.

Jack Lewis
Digital Marketer
Hi, I'm Jack! Before joining S3, I worked in the retail industry, developing my skills in customer service. For me, though, I always wanted something more, something that would actively engage me as well as unleash my creative streak, so Digital Marketing was perfect! Joining S3 Science was the opportunity I had been waiting for, and I was, and still am, looking forward to taking on the challenge with both hands. To be entrusted with a brand that makes such a difference is a massive privilege. Outside of work, I am a massive fan of the theatre and acting in general. I'm hoping to revisit it again someday as a hobby. As well as that, I love the gym! In my opinion, there is nothing better than working out and taking care of yourself both physically and mentally. You will be seeing a lot of my content across the social media channels in the coming months, so please keep an eye on our socials! Thank you for reading

Heidi Cook
Recruitment Consultant
I started off my career in the care industry but decided I wanted a career where I get to speak to a lot of different people as I am a social butterfly.  I have found my passion in recruitment. I love speaking to different candidates and helping them start their careers. Outside of work, I enjoy knitting and gardening, as well as meeting friends for a few drinks.

Katie Wilkinson
Training Administrator
My interest in the industry was inspired by my time as an Animal Technician at B&K Universal. After the business downsized I took redundancy and sought a career in recruitment where I could use my experience and knowledge of an industry I feel passionate about thus joining S3 Science. I am what is known as the ‘cog’ of the company by keeping all administrative aspects of the business functioning. Since joining in 2011 I have had the pleasure of developing my professional skill by having the opportunity to wear ‘different hats’. This allows my job to be completely varied day-to-day from making the initial calls to prospective jobseekers, to compiling contracts of employment, to organising recruitment days, chasing timesheets, making Yorkshire teas and driving forward our presence in social media. Proudest moment/best achievement: Taking full hold of S3 Science’s social media and marketing presence. Generating interest and traffic to our new website by implementing techniques learnt from recent qualifications and courses kindly provided by S3 Science. Outside of work: I am a crazy tortoise lady... my pet ‘bondi’ (that’s him in the pic) wants for nothing, eating fresh pansies and having a huge enclosure in my home. I have travelled the world and am looking to forward to going back to Australia.
