Job Title: Electronic Engineer

Phlux is an award-winning semiconductor start-up based in Sheffield, UK. We have commercialised a breakthrough infrared sensor technology poised to revolutionise advanced driver safety features using LIDAR, ultra-fast low-latency communication networks, and 3D imaging solutions that uncover the invisible.

With over £14M of investment raised to date, Phlux is a revenue-generating company with a team of 20+ skilled professionals spanning operations, sales and marketing, engineering, semiconductor devices, and finance. We are now scaling rapidly and seeking passionate individuals to join our innovative team.

The Role:

Phlux has developed a new class of infrared semiconductor chip that is now in production. The successful applicant will join our engineering team as we ramp production of our first product whilst developing our second product range designed for LIDAR, greenhouse gas sensing, defence and security systems. The second product integrates our infrared detector chip with a low noise amplifier and control electronics into a detector module. This is an opportunity to work on high performance products for many leading ‘brand name’ Tier 1 customers.

In this role, you will join our electronic engineering team and design products specifically for customer applications and a more generic off the shelf product with the candidate having exposure to the full product lifecycle, from concept development to production. While circuit design tasks are involved, the role will have a focus on test, validation, and performance characterisation of analogue electronics. This will involve designing and building new optoelectronic test rigs with help from our optics and electronics experts. The applicant should have excellent organisational and communication skills and be comfortable working independently and with engineers, technicians, marketing, sales, and management.

Key Responsibilities:

• Design and development of analogue and digital electronic circuits including extremely low noise circuits, including transimpedance amplifiers, power supplies, filters, thermoelectric coolers and signal conditioning circuits


• Design and build new test rigs and set-ups for test specialised characteristics of optoelectronics devices, enhancing organisational capabilities

• Characterising the performance of new optoelectronics circuits against customer or internal specifications and ensuring compliance with applicable engineering standards and regulations

• Participating in research and development, NPD and NPI projects

• Work with technical and management teams to develop and upgrade new products on time and with set budgets

• Preparing technical reports and presentations for customer and project partner meetings

As a fast-growing start-up there will be opportunity for the successful applicant to grow technically and professionally as the company scales. Not the least from opportunities to develop new technical and professional skills but to make an impact and see your work come to life through bringing new disruptive products to market.

Qualifications:

• Bachelor’s degree in electronic engineering or a related engineering discipline


• Must be eligible to work in the UK

Skills:

• Proficient in analogue and digital circuit design, including simulation, schematic capture, and PCB manufacturing processes using tools such as Spice, Altium, KiCad, or PADS etc.


• Proficient in product testing, debugging, and result documentation


• Excellent communication and collaboration skills across multifunctional teams


• Strong problem-solving abilities and attention to detail


• Desirable: Embedded software development and microcontroller programming (PIC, ARM, STM).

Experience:

• 5+ years of post-graduate experience in electronics design including:


• Proven track record in hardware development


• Hands-on experience with PCB design, layout, and testing


• Involvement in R&D and new product development projects


• Experience with system and instrument design (desirable)

Goals:

3 months

• Familiarisation of Phlux, the team and the technology.


• Proficient in using optoelectronic components, test setups, and characterising in our devices within the electronics labs, interpreting results.

6 months

• Designing new circuitry supporting operational test rigs enabling the characterisation and the performance of receiver modules, considering their electrical, environmental and mechanical performance.

9 months

• Designing new evaluation boards to support our customers and applications team


• Team delivered beta prototypes (commercial grade prototype) for customer trials

Benefits:

• Competitive salary based on experience.


• Share options with tax efficient EMI stock options - Own a part of the company.


• 25 days annual leave plus bank holiday.


• Exciting and dynamic work environment as part of a growing start-up.


• Pension scheme.
