Lead Data Scientist

London

85-120k

If you’re a hands-on Data Science / AI specialist who loves solving real operational problems, this role puts you right at the heart of client delivery. You’ll shape the problems, design and build the solutions, and see your models deployed into live environments – not parked as endless POCs.

THE COMPANY

This fast-growing consulting firm helps organisations across the public sector, defence and commercial markets deliver measurable improvements in performance through data, AI and digital solutions. They are building a modern AI & Digital capability that sits at the front of transformation programmes, working shoulder-to-shoulder with clients on their toughest operational challenges.

THE ROLE

As a Lead Data Scientist, you will blend hands-on technical work with consulting, stakeholder management and practice-building.

  • Identifying high-impact Data Science, Machine Learning, AI and simulation opportunities on client engagements
  • Scoping and shaping problems, designing experiments and roadmaps, and then building and deploying models end-to-end
  • Leading technical workstreams, managing small teams and ensuring projects are delivered on time and to a high standard
  • Translating complex technical concepts into clear, compelling narratives for non-technical senior stakeholders
  • Coaching and mentoring consultants to build their capabilities in DS/ML/AI and modern analytics

YOUR SKILLS & EXPERIENCE

  • Strong background in Data Science, Machine Learning, AI, simulation or advanced analytics, with clear examples of end-to-end delivery
  • Proven ability to shape, not just execute: from defining the problem and designing the solution, through to delivery and measurement of impact
  • Consulting capability – comfortable running client workshops, identifying opportunities, influencing senior stakeholders and supporting pitches
  • Evidence of measurable commercial or operational impact (e.g. revenue growth, cost reduction, efficiency gains, service improvement)
  • Hands-on experience building models and turning prototypes into robust, production-ready solutions
  • Experience leading teams or technical workstreams in a project environment
  • UK citizenship (for security clearance purposes) and willingness to travel across the UK 2-3 days per week, depending on client needs

Nice-to-have experience:

  • Background in a consulting environment or a high-performing in-house DS/AI team
  • Exposure to sectors such as defence, public sector and consumer/retail
  • Familiarity with modern data and AI tooling such as Python, Spark, Databricks, Azure cloud, and Generative AI platforms (experience with specific tools is helpful but not essential)
  • A mix of technical, product and operational experience – comfortable talking both code and business outcome

Founding Product Engineer

New York

$200000 - $240000

New York

To Apply for this Job Click Here

About the Company

We’re currently working with an early-stage, product-led technology company building a new operating layer for modern work.

Their mission is to reduce cognitive load, eliminate coordination overhead, and help people move from intention to action without sacrificing wellbeing or focus.

This is not another productivity, task, or planning tool.

They are building AI-native systems that can take action, not just make suggestions, while remaining transparent, trustworthy, and fully user-controlled. The product lives at the intersection of AI, UX, and human judgement, and requires careful design to feel empowering rather than opaque or overwhelming.

They are NYC-based, well-funded, and building with urgency.

The Role

We are hiring a Founding Product Engineer with a strong frontend and UX lean to help shape and build the product from scratch.

This is a true founding-level individual contributor role. You will work side-by-side with a small, highly technical founding team, stay extremely close to early users, and help define what the product should be through rapid experimentation.

You will not be handed a polished roadmap, detailed specs, or a mature design system. Instead, you’ll help discover the right product by shipping, testing, learning, and iterating fast.

This role is ideal for a senior, product-led engineer who thrives in low-process, pre-PMF environments and enjoys zero-to-one work.

What You’ll Do

  • Turn product hypotheses into working prototypes within days, not weeks
  • Design AI-native user experiences that feel collaborative, trustworthy, and controllable (not prompt-heavy or opaque)
  • Build simple, opinionated flows to test assumptions directly with users
  • Own meaningful parts of the product end-to-end: UX, frontend, and implementation
  • Work across the stack as needed, with a strong frontend and product focus
  • Collaborate on system shape without premature abstraction or over-architecture
  • Ship quickly, learn from real usage, and iterate or discard work freely as assumptions change
  • Stay close to early customers and incorporate feedback continuously

Who You Are

  • 5-10+ years of hands-on experience building real products
  • Strong frontend skills with excellent UX and product intuition
  • Full-stack capable, but opinionated about user-facing quality
  • Product-first mindset: you care deeply about clarity, trust, and interaction design
  • Comfortable working with partial or ambiguous requirements
  • Curious about applied AI and LLM-enabled workflows, especially user-facing ones
  • Low ego, high agency: you move fast, take ownership, and change direction when users prove you wrong
  • Experience in early-stage startups, very small teams, or zero-to-one builds is a major plus

This Role Is a Great Fit If You…

  • Want real ownership and visible impact from day one
  • Enjoy ambiguity early and bringing structure over time
  • Prefer shipping, testing, and learning over polishing and perfecting
  • Have strong instincts for modern UX and product taste
  • Want to work closely with founders in a tight, fast-moving team
  • Are NYC-based, or are exceptional enough to justify remote-first early on

This Role Is Probably Not a Fit If You…

  • Expect a fully defined roadmap before you start
  • Prefer clean architecture before product signal
  • Optimise for scale, abstraction, or elegance too early
  • Want a narrowly scoped frontend-only or backend-only role
  • Prefer large teams, heavy process, or layered decision-making
  • Are uncomfortable shipping imperfect work to learn faster

Compensation

  • Base salary: $200K-$240K (depending on experience and scope)
  • Equity: Meaningful founding-level ownership
  • Location: NYC strongly preferred (hybrid); exceptional remote candidates considered
