Post-Sales Solution Engineer in London

Salary based on your experience and seniority level: Up to £73,000/year (gross) + 20% bonus. Up to €87,000/year (gross) + 20% bonus.

About Monta: Monta powers the EV charging ecosystem. With 300,000+ monthly users and millions of charge sessions every month, our platform accelerates the electrification of mobility. This is a fast-moving place. The problems are hard, the pace is quick, and the bar is high. If you like real ownership, figuring things out, and seeing the direct impact of your work, you'll do well with us. AI is built into how we work. It helps us ship faster, make better decisions, and stay lean. Everyone at Monta is expected to use AI tools thoughtfully — and to find smart ways to use them to move the work forward. Our principles keep us grounded: Build Together & Finish, Sweat the Details, Customer First, and Aim for the Moon. The best part of Monta is the people — sharp, ambitious, and good to be around. You'll be challenged, supported, and trusted to deliver.

We're looking for a Post-Sales Solution Engineer who's ready to roll up their sleeves, take ownership, and build with us — through the grind and the wins.

This Is What You Will Achieve:

• Own customer relationships technically by becoming the person customers trust to truly understand their setup, their goals, and where they're stuck.
• Accelerate customer time-to-value by running high-quality discovery sessions that get to the real problem fast, then translating that into clear, actionable solutions using Monta's platform and APIs.
• Diagnose and unblock by identifying the root cause of technical blockers customers face, whether that's an integration gap, a configuration issue, or a misunderstanding of what's possible.
• Improve customer implementations by spotting where customers aren't getting the most from Monta and helping them get there, proactively.
• Bridge the gap between customers and Product by turning what you hear and see in the field into structured, real-world feedback that shapes how Monta builds.

What You'll Do:

• Run structured, high-quality discovery sessions with customers to understand their use cases, their setup, and what they're actually trying to achieve.
• Build genuine relationships with customers, becoming a trusted technical advisor who understands their business, not just their ticket queue.
• Own API topics end-to-end: diagnose issues, advise on integration design, and guide customers toward best-practice implementations.
• Identify where customers' implementations could be stronger and help them get there, whether that's a quick fix or a longer-term improvement plan.
• Diagnose the root cause of technical blockers customers are facing and work cross-functionally to resolve them.
• Provide use case advisory, helping customers understand how to get the most from Monta's platform for their specific context.
• Design and map technical solutions that bridge what the customer wants with what Monta can deliver.
• Build internal tools, automations, and resources using Claude and coding skills to remove friction and move faster.
• Develop self-serve documentation, playbooks, and enablement materials that raise the bar on how we support customers technically.
• Stay deeply current on Monta's infrastructure, product changes, and API capabilities, largely through self-directed learning.
• Act as the connective tissue between customers and Product, validating upcoming releases against real customer workflows, flagging gaps before they ship, and feeding back structured insight on what customers actually need.

What We're Looking For:

• Strong technical foundation — deep comfort with APIs (REST, webhooks, authentication flows) and the ability to read, troubleshoot, and advise on integrations.
• Proven ability to learn complex platforms independently. Training won't be handed to you — you'll need to dig in, explore, and build your own understanding of Monta's infrastructure.
• Experience in a solution engineering or technical customer-facing role, ideally within SaaS or a platform/API-driven business — with a track record of owning customer outcomes, not just solving tickets.
• Commercial awareness. You understand that a customer getting more value from the platform is a win for everyone, and you're motivated by that outcome.
• Strong discovery and communication skills — the ability to ask the right questions, listen carefully, and translate technical complexity into clear guidance.
• Self-driven and autonomous. You don't wait to be told what to do — you see what needs fixing and you fix it.
• Structured thinker who can manage multiple customer engagements without dropping the ball.
• Proficiency using Claude or similar AI coding tools to build practical solutions — scripts, automations, internal tools — that solve real problems.
• Experience in EV charging, energy, or mobility tech is a strong plus.
• Comfortable working cross-functionally with Product, Engineering, and Support when needed.

If the mission excites you but your experience isn't a perfect 1:1 match, apply anyway — we care about potential, not perfection.

AI Competency:

We expect everyone at Monta to use AI tools thoughtfully. For this role, that typically means:

• Using Claude to build internal tools, automations, and scripts that remove friction from CS workflows.
• Rapidly prototyping solutions to customer integration challenges.
• Summarising technical findings and turning them into clear, reusable guidance for the CS team.
• Exploring Monta's platform and APIs faster by leveraging AI as a learning and debugging partner.

You'll be expected to work with AI-powered tools. Some we use:

• GitHub Copilot / Claude Code
• ChatGPT / Gemini / Claude
• Notion AI (docs, knowledge, meeting notes)
• Analytics & ML: Langfuse, PyTorch, Mastra
• AI-enhanced testing & monitoring (e.g., generative QA, Grafana ML)

We don't expect mastery of all — but we expect comfort learning, experimenting, and adopting AI responsibly.

Why Monta:

• Impact, not easy mode — your work matters, and you'll feel it every day.
• Ownership from day one — we don't micromanage, we expect you to deliver.
• The grind is real — priorities shift, and flexibility is sometimes needed to get things across the finish line. But so are the rewards: impact, growth, and a team that has your back.
• The people are extraordinary — talented, driven, and fun to work with. You'll be challenged, supported, and inspired in equal measure.

What We Offer:

• A yearly education budget and extra days off to use it.
• A friendly and social company culture with movie nights, Friday bars, pub crawls, and more.
• Free lunch every day.
• Pension (in some locations) & health coverage to keep you secure for today and tomorrow.
• Paid parental leave to support life's big moments.
• Warrants program - be part of our growth story.
• Flexible working hours; as long as you're at key meetings and delivering great work, we trust you to manage your schedule.
• A one month electric vehicle introduction program (plus access to a shared company EV).

Please send us your application in English. To succeed in this position, your spoken and written English skills need to be proficient. Since Monta is a globally active company, you'll be communicating often and regularly with our co-workers and partners around the world, making your professional English knowledge essential.
