Job Title: Senior Scientist (Kinetics Assay Specialist)
Location: Stevenage
Job Type: Permanent 

At LifeArc, we want to hear from people who are as passionate as we are about making life science life changing to improve patients’ lives. 

A bit about the role:

We are looking for an expert scientist with skills and deep experience in surface plasmon resonance (SPR) assay development and screening to measure and characterise molecular interactions in support of our biologics and small molecule programs.  You should have a passionate interest in using your expertise in binding kinetics analysis, as well as epitope binning, target occupancy and other biophysical, biochemical or cellular assay capabilities, to identify the best fit-for-purpose lead molecules for the benefit of patient healthcare. 

This is an opportunity for a knowledgeable and enthusiastic person to join the Biologics Discovery and Development group within LifeArc’s translational therapeutic platforms.  This group is focused on the delivery of high-quality therapeutics to support LifeArc’s portfolio.   Our capabilities include antibody discovery, high-throughput screening, lead antibody characterisation/optimisation, antibody humanisation and protein and analytical sciences.   

This role is positioned within the screening capability stream.  This includes NGS-based recovery and analysis of antibody sequences and high-throughput antibody expression as well as screening from the initial panel of hundreds of molecules through intermediate stages into lead panel characterisation.   You will be responsible for generating key data for both high-throughput screening and lead characterisation stages of multiple projects.  Besides using our SPR-based Biacore and Carterra LSA instruments, you will be expected to also deploy other orthogonal methods available in the lab for measuring molecular interactions such as Octet (BLI) and Nanotemper (Spectral Shift and MST) if required.  In addition, it is vital that the successful candidate is willing to perform activities to cover the entire screening workstream, by utilising existing skills or learning new techniques.  Further, there will be opportunities to apply and expand your skillset across our translational therapeutic platforms.

About you:

A Senior Scientist works independently to perform specialised and non-routine experiments and contribute to the scientific rationale of any assigned projects. Additionally, they will develop and apply their specialist knowledge of scientific techniques/experiments to further project objectives.

  • Be an integral part of the antibody discovery and humanisation campaigns by providing kinetic profiling and epitope binning data using mainly Biacore, Octet and Carterra LSA instruments.
  • Generate full kinetic profiles of antigen binding to lead candidate antibodies and other biologics using SPR (Biacore), with appropriate controls and interpretation.
  • Function as an in-house expert for measurement and analysis of binding kinetics in general, including troubleshooting and optimisation plus taking responsibility for upkeep of instruments. 
  • Perform activities across the screening workstream to enable the team to work in an agile manner.
  • Contribute across projects by providing expertise in kinetic measurement and other biophysical, biochemical or cellular assays.
  • Remain connected with technology developments in the field and advise leadership of potential technology gaps or opportunities that could be of value to bring into LifeArc
  • Conceive, determine, execute and interpret complete range of experiments in assigned project using familiar or new methodologies/techniques.
  • Independently or collaboratively perform analysis of experimental results and develop hypotheses.
  • Summarise, interpret and present results of work (both verbal and written) and validate the interpretation of data and conclusions.
  • Prioritise own work according to project goals.
  • Evaluate and communicate resources and/or timelines to Project Leader/Line Manager to ensure project is sufficiently resourced and achieves its goals according to project plan.
  • Advise management and leadership on project strategies, project plans and project proposals in areas of specialist expertise.
  • Demonstrate, maintain and share knowledge of current scientific literature and developments in own area of expertise, apply it to the successful conduct of experiments and use it to help colleagues.
  • Work closely with colleagues and provide technical guidance and assistance where possible.
  • Maintain, review and approve laboratory notebooks and other data to company standards.
  • Perform all work demonstrating due care and attention to all internal processes and procedures including all health and safety and COSHH regulations.
  • Lead or lead on part of assigned project rationale.
  • Input into and deliver to schedules of work and deadlines, as determined by project requirements.
  • Work within set processes and protocols.
  • Execute research using novel or modified experimental techniques or methodologies.
  • Independently solve new and complex problems by evaluating a range of approaches
  • Define blocks of activity for self and team members where applicable, within a project and monitor progress according to project plan.
  • Facilitate the identification and selection of antibody lead candidates with optimal, pre-clinical drug-like properties.
  • Contribute to LifeArc’s antibody discovery and humanisation capabilities to support worldwide external collaborations.
  • Use experience to enhance LifeArc’s capabilities through continuous development of processes and techniques.
  • Autonomy to make decisions relating to project activities delegated by Project Lead/Line Manager independently.
  • Responsible for the delivery of own workload, and that of team where applicable
  • Follow a work plan horizon of typically up to one month.
  • Support and direct work of team members, where applicable
  • Creates Standard Operating Procedures for equipment as required.
  • Responsible for ongoing equipment maintenance and ensuring users are appropriately trained.
  • Impact of decisions and any resulting issues arising are generally medium term (weeks/months)
  • The time horizon for work is in line with the role’s deliverables which would be months long.
  • Interact with cross-functional internal stakeholders and influence to receive buy-in to scientific ideas.
  • As required, interact with portfolio governance to provide updates.
  • Interact with external stakeholders on a transactional level as required for the project e.g. with suppliers, manufacturers.
  • Present to external scientific community at conferences.
  • Contribute to resourcing decisions as it relates to specialism and/or project.
  • Raise POs for consumables or equipment as requested.
  • May be responsible for equipment purchases.
