The Team
The Engineering team at FundApps is a team of ca. 50 smart, friendly people who collaborate closely and take pride in delivering best-in-class software and providing an extraordinary experience to our clients. We’re solving some of the most challenging problems in financial services - we operate in petabytes and milliseconds, not optimising the upload of cat photos. Our clients use our service for multiple hours a day - what we do as engineers has a real life impact on thousands of people across the globe!

The Role
As part of the engineering team, you'll be working on a suite of innovative products that monitor over US$20 trillion in assets under management every single day, used by some of the world's largest Investment Managers. We are looking for a Mid-Level Back End Engineer who can help drive innovation and deliver great software at pace while also keeping sustainability in mind. We need highly motivated, intelligent people hungry for a challenge.
At FundApps, you'll see the inner workings of a fast-growing, bootstrapped scaleup where we expect all Engineers to take responsibility for their part in our success, seek support when needed, and care equally about our products and client outcomes as you do about writing code. We solve business problems through technology, not just ship code.
We like keeping our tech stack modern and are not afraid to invest to keep it cutting edge! As such we’ve recently completed major projects which included distributing our main rules engine using AWS services, migrated terabytes of data from SQL server to Aurora Postgres, replaced our Single Sign On service with Auth0 and converted our frontend to React.
Our Tech Stack
- Back-end: C#
- Data storage: PostgreSQL; Amazon storage including Aurora, DynamoDB, S3
- Infrastructure: Terraform and AWS, using Fargate, Lambdas, Step functions, and a lot more!
- Pipeline: GitHub Actions, TeamCity, Octopus Deploy, Serverless
- Front-end: React, TypeScript
How We Work
FundApps engineers have a lot of freedom to solve problems in a way that achieves our outcomes, and works within our values. You will not be micro-managed - in fact, it's the opposite - you will be expected to take ownership of your work from Day 1. To thrive at FundApps, you will need to be comfortable with uncertainty, and embrace change as it comes. We value people who take charge of their destiny and help make things better for everyone around them. We release software when it's ready, not on a schedule - our teams deploy multiple times a day.
We work agile, but do not follow any approach blindly - we seek 1% improvements in everything we do, try new things but don't hold to anything too tightly. Fundamentally, we follow a Kanban-inspired approach, but we also take inspiration from Team Topologies, 12-factor, DevOps culture - and all the good agile practices that you have read about. At FundApps we put these practices to work, reflect, and iterate to make sure our practices continue to serve us well.
Our Engineers look after a wide set of products and technical services; we don't strictly follow a micro-services approach, however we are working over time to evolve our codebase and our core technology to be distributed, cloud-native and resource- and cost-effective to power our growth while doing our bit to help FundApps be carbon neutral.
What You'll Bring To The Team
- Background: You are a mid engineer with generalist knowledge of product development concepts (software design, product requirements, work breakdown) and agile practices (TDD, CI/CD, architecture) and can apply them to solve well-defined problems independently and with your team. You are comfortable writing code in C#, Java or Python.
- Work-with-purpose: You can articulate the value of your own work in larger projects or team-wide goals. You have the space to own and deliver solutions and are comfortable working with ambiguity and evolving requirements.
- Have-courage: You are comfortable asking for and giving feedback. You help others when needed, and participate in debates, brainstorms, and other team conversations regularly. You build good relationships with your colleagues in Engineering, Product, and the wider company and are able to respectfully challenge each other to understand the problem and come up with the best solutions. As a company, we embrace change and the chance of failure.
- Be-transparent: As a company, we value and aspire for transparency at all levels; you’ll provide work updates to communicate regularly about progress and blockers and reach out for help when needed.
- Raise-the-bar: You seek out opportunities to improve our code, process, and practices; 1% improvements over time improve things for everyone.
- Do-more-with-less: You identify and help implement improvements to processes and standards within the team, seek to optimise our workflow, and share ideas for how to automate manual tasks. As a company we try to minimise meetings (we have meeting-free Wednesdays) and default to asynchronous written communication over long multiple person meetings.
