Archangel Lightworks is a connectivity company building wireless technology to create the space-enabled networks of the future. We're passionate about improving humanity's communications infrastructure and solving some of Earth's most critical problems from economic inclusion to climate change. Our start-up is a fast-paced and supportive environment, where you can make your mark as part of a growing team and work on the cutting-edge of innovation. 

We're looking for an Optical Systems Engineer with both design and Assembly Integration and Test (AIT) experience to join our engineering team and deliver transformative laser communications technology. You will be responsible for the development of our optical subsystems, from requirements definition to testing in the field. In this role, you will work closely with our Lead Systems Engineer and optical engineering team.  

Your responsibilities will include:  

• Design of laser communication terminal optical sub-systems for extreme environments (e.g. telescopes, relays etc.). 
• Requirement definition and trade off analysis for complex optical systems, finding the optimal balance of performance against cost. 
• Modelling of optical system performance, optimization and tolerancing. 
• Conducting practical breadboard testing to validate modelled data. 
• Working with AIT engineer(s) to define and execute test procedures for optical subsystems. 
• Being the subject matter expert for optical and photonic systems. 
• Managing suppliers of optical and photonic components. 
• Providing technical leadership of subsystem development projects. 

Requirements: 

• Experience defining requirements on optical systems, modelling and performing trades studies to inform design selection. 
• Optical design/analysis experience using Zemax for design, optimization and tolerancing. (Sequential, non-sequential desirable). 
• Hands on lab experience designing and carrying out tests for relevant optical systems. 

Desirableadditional skills: 

• Technical project planning and systems engineering experience, ideally in a Model Based Systems Engineering context. 
• Experience designing complex Electro Optical Systems for extreme environments in mass constrained applications, beyond just the optical design e.g. optomechanical design, electronics, software. 
• Experience with adaptive optics, turbulence modelling, measurement and compensation methods. 
• Experience with high power lasers, optical amplifiers, and relevant safety requirements. 
• Experience with optical instrument calibration and alignment, and procedure definition. 
• Familiarity with optical and photonic components relevant to free space optical communications. (e.g. types of lasers, fibers, splitters, amplifiers, quadrant detectors, CMOS, focal plane arrays, filters and coatings, etc.) 

Location: Hybrid with travel when required. Our office is based in Osney Mead, Oxford. 

Position details: We will consider applications for permanent hires and contractors. 

Compensation & Perks: 

• The opportunity to make a difference building cutting edge technology to support a world-changing vision. 
• Options for hybrid working and custom arrangements that matter to you. 
• 25 days annual leave allowance plus bank holidays. 
• Equity options in a growing start-up. 
• Investment in you to help you grow, with training resources and budget. 
• Supportive team culture with high levels of ownership and responsibility. 
• Annual team retreat, regular socials and weekly team lunch. 
• Variety of additional perks including learning and wellbeing app subscriptions.
