Introducing the Trainline Machine Learning and AI Team 👋

Machine learning is at the heart of Trainline’s mission to help millions of people make sustainable travel choices every day. Our models and AI agents support customers when journeys go wrong, power search and recommendations across our apps and website, find the best fares through pricing and routing optimisation, personalise the experience with generative AI, and make our digital marketing smarter. Our teams own the full lifecycle from idea to production, and work closely with colleagues across the business to grow the impact of ML and AI at Trainline.

We’re looking for a Machine Learning Engineering Manager to lead a team of 7 ML engineers and data engineers within our Core Experience pillar, which covers Search, Supply and Commerce. Your team’s work sits at the centre of how customers find, compare and buy their tickets. You’ll be accountable for what your team ships and how it ships it: the quality of the systems, the pace of delivery and the growth of the people building them. You’ll work alongside data scientists, software engineers and product managers. You’ll stay close enough to the technical work to make good calls on architecture, trade-offs and risk. What unites us is curiosity, a love of what we do and a desire to make sustainable travel the easy choice.

In this role, you will... 🚄

• Lead, coach and grow a team of ML and data engineers. That means setting clear expectations, giving regular feedback, managing performance and building an inclusive team where people do their best work

• Hire for the team, shaping the roles we need and running a fair, rigorous interview process

• Own delivery: plan and prioritise with your product partners across Search, Supply and Commerce, unblock the team, and ship ML and AI systems that move measurable customer and business outcomes

• Set the technical direction for your team’s systems, including architecture, build-versus-buy, and knowing when a simpler approach beats a more sophisticated one

• Make sure the team builds well across the whole lifecycle: reliable data pipelines, high-quality features, rigorous offline and online evaluation (including A/B testing), reliable deployment, monitoring and ongoing maintenance

• Lead the team in building production-grade agentic systems, using orchestration harnesses such as LangGraph to design multi-step workflows, tool use and human-in-the-loop controls

• Make evaluation a first-class engineering discipline for LLM and agent work. That means curated eval sets, LLM-as-judge and human review, tracing, regression testing of prompts and agents, and online monitoring of quality, cost and latency

• Set the guardrails for responsible use of AI, covering safety, privacy and clear fallbacks when an agent shouldn’t act on its own

• Raise the bar on engineering practice through code and design reviews, CI/CD, MLOps, observability and on-call

• Build strong relationships with senior leaders and partner teams, explaining progress, trade-offs and impact in plain language

• Contribute to our wider AI and ML community and help keep a culture of learning, curiosity and experimentation

We’d love to hear from you if you have... 🔎

• Experience line-managing engineers, including hiring, performance management and career development

• A strong background as an ML engineer, with a track record of taking models into production and keeping them healthy at scale

• Enough grounding in data engineering (pipelines, data modelling and data quality) to lead data engineers as well as ML engineers

• Solid Python and software engineering fundamentals, with enough hands-on depth to review code and designs credibly

• Depth in at least one area such as ranking and recommendation, predictive modelling, optimisation or NLP, backed by a solid grasp of statistics, experimentation and feature engineering

• Experience with modern ML infrastructure on a major cloud platform, ideally AWS, covering distributed data processing, orchestration, model management and infrastructure as code

• Hands-on experience shipping agentic or LLM-based systems, including agent orchestration frameworks, tool use, RAG, and fine-tuning where it earns its place

• A disciplined approach to evaluating LLM and agent systems, using tools such as Braintrust, and a clear view on how to know whether an agent is working well in production

• Clear communication with technical and non-technical colleagues, and good judgement on priorities when there’s more to do than people to do it

Our tech stack 💻

We build mostly in Python on AWS, and choose tools for what they do in production rather than for novelty. You don’t need to know all of it on day one.

• Data and compute: S3, Athena, Spark on EMR, SQL

• Orchestration and MLOps: Airflow, MLflow, Docker, ECS, Terraform, GitHub Actions for CI/CD

• Models: foundation models served through Amazon Bedrock

• Agents: LangGraph for orchestration, deployed and run on Amazon Bedrock AgentCore, with MCP for tool integration

• Evaluation: Braintrust for evals, tracing and monitoring agent quality in production

We’re looking for a passionate Forward Deployed Engineer to join our team at STRATOS – someone eager to sit at the intersection of cutting-edge technology and real-world impact.

As a Forward Deployed Engineer, you’ll work shoulder-to-shoulder with industry leaders to embed our platform deep into their operations – transforming strategic intent into live systems that drive measurable results. In today’s world, where the last mile of implementation creates the competitive moat, you’ll be the catalyst turning software into scale.

About Us

At STRATOS Technologies, we are transforming how companies make data-driven decisions with our innovative Strategy Operating System. Our software integrates complex datasets into a unified solution, enabling businesses to strengthen their long-term strategies through clear and actionable insights.

Our founders, former business and tech executives who led a $1B division at a Fortune 500 industrial company, originally built a digital twin of their enterprise to drive synchronized planning and execution. Seeing the market’s lack of such a system, they launched STRATOS in 2022 with a bold mission: to build the world’s first strategy operating system that unifies all internal and external data into a single platform.

Today, STRATOS is a category-defining, rapidly growing startup funded extensively by high-profile investors (e.g., Accel) and trusted by nearly a dozen global industrial leaders and Fortune 500 customers. Our software integrates complex datasets into a unified solution, combining deep data integration, best-in-class workflows, and cutting-edge generative AI.

From commercial AI agents to embedded intelligence that supercharges lean teams, STRATOS enables businesses to achieve 10x productivity and strengthen long-term strategies through actionable insights. We are now expanding our team to accelerate our growth even further and help our customers outperform their competition.

Why Forward Deployed Engineering

While we have a scalable technology backbone, we believe that Forward Deployed Engineering is the future of differentiated B2B SaaS in the GenAI age. Rather than shipping static tools, we partner closely with customers to deliver dynamic, tailored solutions where value is created in the implementation layer – not just the codebase.

Tasks

• Ensure client implementations are working successfully

• Solve our customers’ hardest business challenges by adapting and deploying the STRATOS platform to their needs

• Design and implement scalable generative AI workflows using platforms like Palantir AIP

• Execute complex data integration using PySpark and other distributed technologies

• Collaborate directly with clients to understand context, priorities, and key outcome

Requirements

• 0-4 years of solid experience in data engineering or analytics.

• Experience at start-up companies and/or an excitement to experience first-hand the adventure that comes with a fast-scaling tech company, alternatively experience at a top-tier consultancy.

• The ability to translate complex and sometimes ambiguous business requirements into clean and maintainable data pipelines

• Excellent knowledge of PySpark, Python and SQL fundamentals

• The ability to get to grips with new technologies quickly

Preferred Skills and Qualifications

• Experience in dashboarding tools, Typescript and API development

• Familiarity with Airflow, DBT, Databricks

• Experience working with Enterprise Resource Planning (e.g. Oracle, SAP) and CRM systems

Benefits

• Equity through our stock option programme, so you share in the long-term success and growth of the company

• A highly competitive salary

• Direct access to Fortune 500 executives from your first months, at a level most people wait a decade for

• Work alongside former MBB consultants and Fortune 500 executives who will teach you directly — our team is small enough that this happens in person, not through a training curriculum

• Private healthcare

• Pension scheme

• 25 days of annual leave, plus bank holidays

• Work from abroad — up to four weeks a year, and up to two weeks at a time

• Hybrid office policy, with visa sponsorship available

• A company committed to social and environmental responsibility — we pledge to be a net-zero CO₂ company and donate 1% of our revenue to social causes

Practicalities

• London-based, 3 days a week in our Farringdon office
