Why work for us?
A career at Janus Henderson is more than a job, it’s about investing in a brighter future together.
Our Mission at Janus Henderson is to help clients define and achieve superior financial outcomes through differentiated insights, disciplined investments, and world-class service. We will do this by protecting and growing our core business, amplifying our strengths and diversifying where we have the right.
Our Values are key to driving our success, and are at the heart of everything we do:
- Clients Come First - Always
- Execution Supersedes Intention
- Together We Win
- Diversity Improves Results
- Truth Builds Trust
If our mission, values, and purpose align with your own, we would love to hear from you!
Your opportunity
This is a hands-on engineering leadership role. You will build, and you will lead the people who build. It starts with your own hands on the keyboard; it grows into ownership of a team, its deliverables, and the roadmap they work to.
Janus Henderson is undertaking a firm-wide AI transformation to become the most technologically sophisticated asset manager in the industry. Our AI capability sits in a single centralised function under the Head of AI, and Forward Deployed Engineering is the part of it that embeds with the business and builds what business units cannot stand up alone. As Principal Forward Deployed Engineer you are the most senior engineer in that team and its lead. Reporting to the Head of AI Technology, you set the technical bar, own the team’s deliverables and outputs, and are accountable for what it ships and runs — while still embedding with business units yourself.
You will also form part of the AI Technical Leadership Team, whose remit is to build an AI Technology roadmap that lines up with the JHI strategic roadmap and own the deliverables against it. It works across every AI technology remit — AI Platforms, AI Architecture, AI Engineering, and AI Governance Implementation — keeping them aligned so the firm has one coherent plan rather than four competing ones. It also decides what we adopt: you will review new models, tools, and vendors, test their claims against our own workloads, and judge whether they are feasible here, technically, commercially, and against the constraints a regulated asset manager operates under.
The balance of the role will shift, and we would rather be explicit than discover a mismatch later. Today it is predominantly hands-on: you are expected to be one of the strongest builders in the firm. As the team grows, the weight moves towards strategy, roadmap, and management, and your technical contribution shifts from writing most of the code to setting direction and holding the standard. If you want to stay purely hands-on, the Forward Deployed Engineer role is the better fit.
What success looks like
- Your team ships. Solutions reach production, are used, and stay healthy — and you can point to the business outcome, not the delivery activity.
- You are still trusted technically. Engineers bring you the hard problems, and you are close enough to the work to help.
- The Forward Deployed Engineering roadmap is sequenced, agreed with the AI Technical Leadership Team, and lines up with the JHI strategic roadmap.
- Technology decisions are evidence-based, and your engineers grow — people join, get productive quickly, take on more, and stay.
Your responsibilities
Lead the team and own its deliverables
- Line-manage Forward Deployed Engineers as the team grows: hiring, onboarding, objectives, development, and performance.
- Own the team’s deliverables and outputs — what is committed, what is delivered, to what standard, and by when.
- Allocate people and effort across the demand pipeline, and be the person who says no, not yet, or not like that.
- Hold the engineering bar through design and code review, and grow engineers into owning engagements themselves.
- Report progress, risk, and capacity to the Head of AI Technology and to business stakeholders honestly, including when delivery is off track.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Build and deliver, hands on
- Design, build, and productionise bespoke, higher-complexity AI solutions yourself, taking the hardest and least-defined engagements personally.
- Own the architecture and design decisions for the team’s solutions, keeping them secure, scalable, and aligned to the enterprise core stack.
- Take solutions through evaluation, observability, and our AI governance checkpoints, and keep them healthy afterwards.
Own the roadmap and the technology choices
- Form part of the AI Technical Leadership Team, and build an AI Technology roadmap that lines up with the JHI strategic roadmap.
- Work across the AI technology remits — AI Platforms, AI Architecture, AI Engineering, and AI Governance Implementation — owning the Forward Deployed Engineering deliverables and keeping them aligned to enterprise architecture.
- Contribute to AI technology strategy, standards, and buy-versus-build, and to the investment recommendations and backlog that follow.
- Review new models, tools, and vendors and determine their feasibility here, weighing cost, licensing, security, supportability, and vendor viability alongside capability, and documenting the recommendation — including the recommendation not to adopt.
Embed with the business and build investment capability
- Sit with business users and hold the relationship senior enough that the team is invited into problems early rather than handed finished requirements.
- Partner with the AI Enablement Partners on escalated demand, and set realistic expectations with senior stakeholders.
- Build advanced investment capability on Nexus, our agentic workspace, taking models and signals from one desk into a supported, firm-wide capability, and lead the build-out of citizen developer workflows through to production.
- Expose data and capability through Accio, our centralised MCP server, and as skills, tools, and connectors on Nexus, building reusable components rather than one-off integrations.
- Co-build enterprise core-stack deliverables with Percepta and AI Engineering, and represent Forward Deployed Engineering in architecture and design authority forums.
What to expect when you join our firm
- Hybrid working and reasonable accommodations
- Generous Holiday policies
- Excellent Health and Wellbeing benefits including corporate membership to Wellhub
- Paid volunteer time to step away from your desk and into the community
- Support to grow through professional development courses, tuition/qualification reimbursement and more
- Maternal/paternal leave benefits and family services
- All employee events including networking opportunities and social activities
- Lunch allowance for use within our subsidized onsite canteen
Must have skills
- At minimum eight years in technical, business-facing engineering roles — forward deployed engineering, solutions engineering, consulting-side software engineering, or engineering embedded in a business unit — including time as the most senior engineer on the work. Former technical founders are encouraged to apply.
- Experience leading engineers as a line manager, tech lead, or founder. You need not have run a large team, but you must have been accountable for other people’s delivery.
- Strong Python and SQL, and a track record of shipping production applications, with hands-on delivery recent enough to still be real.
- Production experience with LLMs — prompt and context engineering, agent development, evaluation, deployment at scale — including agentic capability such as MCP servers, tools, or connectors.
- Experience building data pipelines from APIs and enterprise systems, and working knowledge of a major cloud, ideally Azure, with CI/CD, containers, and infrastructure as code.
- Experience owning a technical roadmap, and judgement on technology selection — you can evaluate a new tool, model, or vendor, test it properly, and defend the recommendation.
- Excellent stakeholder skills, credibility with senior audiences, and the ability to influence without direct authority.
- High agency, genuine interest in the business problem, and willingness to move from building towards leading as the team grows.
- Experience in a regulated environment where governance, compliance, and data sensitivity shape how solutions are built.
