Tech Lead (React Native + JavaScript)

We are Citi’s Application, Platform and Engineering team, a start-up with the exciting mission of shaping the direction of travel for the entire bank under the Chief Technology Office, by defining the tech and engineering strategy for the bank. We are a team of talented engineers, product managers and tech SMEs, taking ambiguous concepts and making them real by engineering cutting edge products at planetary scale! We are solely focused on the most modern technology and engineering disciplines such as generative AI, cloud, security, modern app stacks (with Golang, Gatekeeper), open source and the latest and greatest in the Kubernetes ecosystem.

Generative AI is a growing space, as a result, we ask that you share with us any specific AI engineering projects utilising LLMs that you’re proud of in your application. Ideally these projects should show off complex and clever architectures or a systematic evaluation of an LLM’s behaviour.

Bring your deep-dive software engineering expertise. Be a game-changer, ready to step beyond your designated role. Love the synergy of pair programming? Seize the opportunity to explore machine learning and its real-world applications at scale.

• Fluency in Golang is a must-have, (Python is a desirable addition)
• Experience designing control and sandboxing systems for AI experimentation
• Understanding of language models and transformers
• Direct engineering experience of high performance, large-scale ML systems
• A contributor to opensource and always thinking out of the box tooling, using and standardizing with methods of creating APIs, ML/Ops automation and more.

We do not have boundaries between engineering and research, and we expect all our technical staff to contribute to both as needed. We take a product-focused approach and care about building solutions that are robust, scalable, and easy to use. We enjoy working in a fast-paced team tackling cutting-edge problems by constantly testing and learning. We enjoy pair programming for our products, we are lean in our approach and remove bureaucracy where we see it.
