Infrastructure & Operations Team Lead

Job Description

LMAX Group is a FinTech company that designs, develops, builds and runs leading edge financial exchanges in major financial centres around the world, specialising in fiat and crypto currencies.
We are growing, and we want a senior technologist to join us for the next step in their career. We're creating a new position, one that blends engineering, operations, and team management.
The Role
Infrastructure & Operations Team Leads are responsible for managing a team of data centre and infrastructure specialists, and are the focal point of our operational resilience, incident response, and infrastructure lifecycle functions.
Our newly forming Infrastructure Team will own our operational and monitoring functions, as well as our global infrastructure provisioning and build processes, helping define how this team functions and provides services to teams. They will drive automation and improvements to streamline these areas. A key responsibility for the success of this role will be creating a space and culture for onboarding and enabling engineers near the beginning of their careers.
There will be some element of project and workstream management, and the position includes line management responsibilities for engineers with a range of skill sets. We expect up to a 60/40 managerial vs technical split of day-to-day activities, and we expect the mentoring and training aspect of the role to be an important part.

You have a strong operational background and are technically proficient.

· Mentoring junior staff, setting goals, balancing delivery vs learning, managing workloads and expectations.
· Excellent written and verbal communication - collaboration with stakeholders and teams in a Follow-The-Sun model of working.
· Line management and people management of geographically dispersed team.
You are interested in or may have some of these skills
· Strong organizational skills - you've run operational teams before.
· Worked with Infrastructure-as-Code practices and tooling, and in a DevOps culture (Puppet, Ansible, Terraform).
· Familiar with physical infrastructure and data centres.

Team culture
With our "everyone can work on anything" culture, our engineers have opportunities to expand their skill set across many fields; system and platform automation, on-premises and cloud infrastructure, performance tuning, networking, CI/CD pipelines, and software testing.
We're big fans of automation and testing. We'll encourage you to think like a software engineer by applying a Test-Driven Development approach to the things we build. We think you'll find it ends up being faster, giving more time for the interesting problems.
We have 50/50 flexible working from home and in our offices. We encourage you to take half a day every week for your own learning and development, and we provide a large range of training resources and opportunities.

Job Title

Software Developer (Future Finance)

Job Description

LMAX is renowned for its high-performance, ultra-low latency (we measure in microseconds) exchange written in core Java. We constantly push technology further than most, especially in our greenfield projects. Together, we will be driving the financial industry in new directions.

Finance is going to be tokenised through the use of blockchain technologies. We want to be at the forefront of that wave, working with the institutions to build efficient, regulated and fair markets. We have gone from one developer to a small team over the last year and have already built a brand new trading solution, taking the best of centralised liquidity and decentralised security. It is live on public blockchains, we're not just prototyping. Our vision is a lot more than just this, so we need to grow into multiple teams as we shape the future of the financial landscape. Our roadmap is heavily developer driven, with CEO buy in, meaning you can substantially influence the direction of the project.

Developers are encouraged to constantly develop and learn new skills. Pair programming supports continual growth of knowledge and sharing of expertise. Friday afternoons are set aside as personal development time where you can explore new languages, research bleeding edge technologies, or even come up with brand new projects pushing the boundaries of finance. There is regular time to improve developer experience and reduce technical debt.

Our continuous integration and testing culture allows us to have confidence in our builds and develop quickly. We have already built a suite of new tools to maintain this mission with our dynamic tech stack. Continuous Delivery was pioneered at LMAX (one of the authors worked here while writing the book). Due to pair programming and testing we don't do pull requests, we push directly to our monorepo with a "revert first, ask questions later" attitude.

If you want to work in an environment that follows great developer practices such as fast feedback across all aspects of your work, a cooperative culture, and only shipping things when they're ready, while being at the heart of the finance revolution, then the LMAX future finance team is for you!

What you should expect:

Collaborative office environment with constant pairing and plenty of social activities
Work across the stack to solve a problem - From building a new exchange one day and creating new financial products through the use of smart contracts the next. We do it all, and do it properly
Regular opportunities to learn and develop yourself with internal tech talks, ability to travel to conferences, and dedicated time for your personal development


What you'll be working with:

Backend: Distributed, event-driven core Java 21 (80% of the code-base), MySQL, Kafka, Solidity (EVM Smart Contracts), Rust (Solana Smart Contracts)
Frontend: Javascript, Vue.js
Deployment: Kubernetes, AWS
Testing: JUnit, Hardhat, Jenkins, Selenium, many in-house tools..
OS: Linux

The LMAX way is to use the right tool for the job so this is just a flavour of what you'll be working with and isn't a list of requirements!

Requirements

Be passionate about software development. Bad code offends you!
Work in a dynamic environment enabled by fast feedback; the heart of our ethos
Pair programming in small teams of developers and testers (who also write code)
Share knowledge and learn from like-minded peers
Write performant, reliable, and well tested code - shipping only when it's ready
