Frontend React Developer

We are seeking an experienced and passionate Senior Frontend React UI Developer to build out our front-end web application, which will allow the users to create a graphical model interactively and collaboratively, view models, upload data and run models on that scenario data, as well as visualising sampling results. Over the past year, we have built out the functionality to present the probabilistic graphical network model, allow the user to configure the model for sampling, and view a rich set of results, with the ability to compare different runs, and view sampling results per node and multi-node. However, the graphical network model is still built off-platform. We are currently building out a sub-application which allows the modelling team to collaboratively build the model using web-sockets, and load that into the existing system – think a multi-user Google Docs or Office 365 interactive session. We also want to build out screens which allow the user to connect time-series data to a node, and load the time-series into the system, calibrate the model, as well as embellish the functionality we currently offer in the system. You will collaborate with other members of the team and define interface components required and be responsible for building out custom React components, and making changes as required. You will have influence on both the design and implementation, to participate in code reviews and ticket prioritisation.

Responsibilities:

• Work with the wider team to determine UI features required for development and their functional requirements in sprint and planning based on business requirement.
• Experiment and develop custom high quality UI components to implement the model builder, result visualisation and data catalogue components.
• Integrate UI components against backend API functionality, and propose backend changes.
• Deploy Front End components using Infrastructure as Code.
• Engage in cross-team project meetings/code reviews/demos in an agile environment.

What we’re looking for:

• Expert in ReactJS and vanilla Typescript, NPM, Vite or alternatives.
• Strong knowledge of web-sockets (socket.io / wss).
• Strong proficiency in building data visualisations and data flow (we need to allow users to create and edit base model graphs (DAGs)) – Dagre or ReactFlow (or similar alternatives) and creation of custom UI componentry.
• Experience in creating custom charts (e.g. Chart.js, d3.js) to show sensitivity, compare timeseries data and sampling results.
• Interact with the RESTful API that we develop to trigger jobs asynchronously and retrieve sampling results from the storage layer.
• Knowledge of how to test the developed front-end componentry.
• Interested in shaping the backend Python API or becoming involved in full stack development.

Desired/Obtained Qualifications and experience:

• Some general knowledge of Bayesian networks or probability would be helpful.
• Experience working closely with data scientists and other stakeholders, not just developers, and be comfortable demoing their work.
• The product will be very iterative in terms of feature set and technologies, so needs to be comfortable with unknowns and evolving, sometimes vague requirements and tickets.
• Knowledge of Python (we run system components in dockerized containers to not need to deploy all of the time).
• Familiarity with Docker.
• Strong knowledge of Git and Gitlab CI/CD.
• Excellent communication in a geographically distributed team – innovative and inventive, able to pair program and collaborate.
• BS/MS Computer Science/Engineering.
