Job Description

You will be joining a multi-disciplinary research team in the UK, working closely with other engineers, to lead the development of III-V active components - primarily semiconductor optical amplifiers (SOAs) - integrated on our silicon. As the technical owner of our SOA technology, you will take devices from epitaxial stack and device design, through fabrication with our III-V and silicon photonics foundry partners, to characterisation, reliability and qualification.


What you'll be doing

  • Work hands-on and lead the design and modelling of III-V SOAs and related active components, including epitaxial layer structure, gain and saturation power modelling, optical mode design, and electrical and thermal design
  • Own the SOA technology roadmap and device specifications, translating system requirements (gain, saturation output power, noise figure, polarization dependence, linearity and thermal budget) into device design and integration targets
  • Lead mask design and tape-outs: generate and review GDS layouts, test structures and design-of-experiment splits
  • Manage fabrication runs with external epitaxy, III-V and silicon photonics foundry partners: define process flows and specifications, review process and in-line data, resolve yield issues and support the transition into volume manufacturing
  • Define and lead the characterisation strategy for SOAs at wafer, chip and integrated-PIC level (LIV, gain and ASE spectra, noise figure, saturation output power, polarisation-dependent gain, temperature dependence), including building and automating test setups
  • Analyse test data, correlate measured performance with design and process variations, identify performance gaps and drive design iterations to close them
  • Work with packaging and reliability engineers on burn-in, accelerated ageing, failure analysis and qualification of SOA devices
  • Mentor engineers now and, as the team grows, recruit, line-manage and develop a small team of III-V design and test engineers

Essential requirements

  • Ph.D. in physics, photonics, electrical engineering, optical engineering or a related subject with 6+ years' relevant experience, or a Master's degree with 8+ years' relevant experience; including at least 4 years' hands-on development of III-V SOAs or semiconductor lasers, preferably in industry
  • Demonstrated track record of taking SOAs (or semiconductor lasers) from concept through design, fabrication and test, ideally including devices taken through qualification
  • Deep understanding of semiconductor laser and amplifier physics: optical gain, carrier dynamics, quantum-well design, amplified spontaneous emission and noise, gain saturation and nonlinearities, thermal effects and polarisation dependence
  • Hands-on knowledge of III-V epitaxy and fabrication processes (e.g. MOCVD/MBE growth, lithography, etching, passivation, metallisation, facet/AR coating), and experience working with external foundries
  • Experience with characterising SOAs or lasers, including optical spectrum analysers, gain and noise-figure measurement, wafer-level probing, temperature-controlled testing and test automation
  • Experience with mainstream simulation and layout tools for active and passive photonic devices, such as Lumerical (including MQW/CHARGE/HEAT), Photon Design (PICWave, FIMMWAVE/Harold), Crosslight, RSoft, COMSOL, KLayout, L-Edit or Cadence Virtuoso
  • Proven ability to lead technical projects and coordinate across design, process, test and packaging functions, together with experience mentoring or supervising engineers
  • Excellent communication skills, critical thinking, attention to detail and self-motivation

Nice to have

  • Experience integrating III-V active devices with silicon photonics, including mode conversion and coupling design between III-V and silicon waveguides
  • Experience line-managing a technical team, including recruitment and performance development
  • Experience with reliability testing and failure analysis of III-V devices (e.g. accelerated ageing, catastrophic optical damage)
  • Experience developing PDK building blocks or compact models for active devices
  • Experience in programming languages, such as Python, MATLAB or C++, for simulation, test automation and data analysis
  • Knowledge of photonic packaging, including fibre coupling, thermal design and TEC control
  • Demonstrated ability to generate high quality patents and research papers

Job Description

Starling is the UK’s first and leading digital bank on a mission to fix banking! Our vision is fast technology, fair service, and honest values. All at the tap of a phone, all the time.

Starling is the UK’s first and leading digital bank on a mission to fix banking! We built a new kind of bank because we knew technology had the power to help people save, spend and manage their money in a new and transformative way.

We’re a fully licensed UK bank with the culture and spirit of a fast-moving, disruptive tech company. We’re a bank, but better: fairer, easier to use and designed to demystify money for everyone. We employ more than 3,000 people across our London, Southampton, Cardiff and Manchester offices.

Our technologists are at the very heart of Starling and enjoy working in a fast-paced environment that is all about building things, creating new stuff, and disruptive technology that keeps us on the cutting edge of fintech. We operate a flat structure to empower you to make decisions regardless of what your primary responsibilities may be, innovation and collaboration will be at the core of everything you do. Help is never far away in our open culture, you will find support in your team and from across the business, we are in this together!

The way to thrive and shine within Starling is to be a self-driven individual and be able to take full ownership of everything around you: From building things, designing, discovering, to sharing knowledge with your colleagues and making sure all processes are efficient and productive to deliver the best possible results for our customers. Our purpose is underpinned by five Starling values: Listen, Keep It Simple, Do The Right Thing, Own It, and Aim For Greatness.

Hybrid Working

We have a Hybrid approach to working here at Starling - our preference is that you're located within a commutable distance of one of our offices so that we're able to interact and collaborate in person. We don't like to mandate how much you visit the office and work from home, that's to be agreed upon between you and your manager.

Our Data Environment

Our Data teams are excited about the value of data within the business, powers our product decisions to improve things for our customers and enhance effective and agile decision making, regardless of what their primary tech stack may be. Hear from the team in our latest blogs or our case studies with Women in Tech.

People with a broad ability to apply themselves to a multitude of problems and challenges, who can work across teams do great things here at Starling, to continue changing banking for good.

Requirements

We have built our entire banking platform in house and mostly in Java. We are looking for people who want to work on building the tooling that is used by our engineers on a daily basis.

We are looking for people who are truly full stack, and are as comfortable polishing their javascript front end as they are debugging the innards of their java applications database interactions, or standing up infrastructure with terraform. We are looking for people who can:

  • Design REST apis.
  • Code backend services, ideally using Java, or another other server side compiled language.
  • Develop modern front ends, ideally using React and Redux.
  • Get their code into the cloud and support it there, ideally on AWS.
