About the role:

You'll own the top of the funnel: outbound, qualification, and getting leads to sit down for a conversation. Demos, onboarding, and retention are staying with the founder for now.

Phase one: Get individual Automation QAs to try the product, aiming for fast adoption and no procurement. Once we hit 20+ weekly users, we’ll move on to phase two, where we’ll shift the focus to B2B – qualified meetings with QA Leads and Engineering Managers.

Your focus in the first three months:

• Build targeted lists: Automation QAs at companies with web products and Playwright, Cypress, or Selenium in their stack.
• Run outbound sequences (LinkedIn is the baseline, but you decide the channels). A/B test weekly.
• Design qualification gates (forms and scoring) to filter leads before the founder calls.
• Reach 20+ weekly active users after month one – ICP-qualified and giving direct feedback to engineering.
• Document what works into a repeatable playbook.

Growth path:

This role expands as your strategies deliver results. Once the user pipeline works, you can take over demos and run B2B sales end to end. From there, the natural next step is Growth Lead (funnel optimization and scaling the playbook) or Account Executive (owning deal execution).

Why to join:

• You'll be building a strategy that scales the product, not filling a quota. What you create from scratch becomes the foundation.
• Your outreach turns into users who talk directly to engineering, and their feedback ships as features within days.
• AI for developer tools is a market with real pull, and QA automation is one of its sharpest pain points.
• We’re backed by JetBrains – financially secure with no reliance on external VC funding.

Who we're looking for:

You should have a high level of agency and be quant-minded – you live in funnel metrics, run experiments, and are comfortable saying "no" to leads that are a bad fit. 

The ideal candidate will:

• Have done 0-to-1 outbound for an early-stage devtool, QA tool, infrastructure product, or similar.
• Have proven cold outbound results, instead of being dependent on warm inbound.
• Be able to talk credibly about flaky tests, CI pain, and Playwright vs. Cypress. You don't need to be an engineer, but you do need domain empathy.
• Possess strong written communication skills, with the ability to craft short, sharp messages that get replies.

Nice to have:

• A QA or SDET background – you've felt the pain yourself before moving to sales or BD.
• Exposure to security/compliance objections – enough to pre-empt and route.
• Content skills – your LinkedIn posts get engagement, not just your DMs.
• Experience as one of the first 10 employees at a startup.

The Role

We're hiring a Frontend Engineer to lead the architectural evolution of our UI. You'll define the design patterns, component abstractions, and typing contracts that allow the wider engineering team to ship features quickly without compromising the architecture.

Our frontend is where massive datasets, predictive models, and AI systems become usable - fast, data-heavy interfaces that let users explore energy markets, interrogate datasets, and interact with complex forecasting models in real time. The stack is TypeScript, React, and Next.js in a modern monorepo architecture built for rapid, AI-assisted development.

What You'll Do

• Lead the technical direction for our frontend monorepo - state management, routing, and module boundaries within Next.js and TypeScript
• Design and develop our internal UI component library (built on MUI) - reusable, strictly typed abstractions that serve as building blocks for the engineering team and AI agents
• Build and improve high-performance, low-latency interfaces - profiling performance, minimising re-renders, and keeping the platform responsive under heavy data loads
• Set the architectural patterns and coding standards that govern development, including oversight of high-volume AI-assisted contributions
• Act as the primary technical authority for frontend - guiding the team on UI best practices and effective use of AI coding tools

What We're Looking For

The Essentials

• 3+ years of professional frontend development experience
• Strong proficiency in TypeScript, React, and modern JavaScript
• Hands-on experience with Next.js
• Experience with Material UI (MUI) or a comparable component library
• Strong eye for UI/UX - you can bridge the gap between design and engineering and build polished, production-quality interfaces
• Solid understanding of testing principles with frameworks such as Jest, Cypress, or Playwright
• Proficient with Git, Docker, and CI/CD workflows
• Familiarity with monorepo structures and tools (Turborepo, Yarn Workspaces, or similar)

Nice To Have

• Familiarity with Python and/or energy forecasting models
• Experience in energy markets or data-heavy analytical products
• Startup or scale-up background

Compensation, Legal, & Equal Opportunity

• Benefits: Salary sacrifice pension with 3% employer contribution; 25 days annual leave (excluding bank holidays), plus 5 flexible days to be taken on a Monday or a Friday; top-tier private healthcare and dental coverage.
• Compensation: £70k - £90k per year
• The salary range listed reflects industry benchmarks for this role. Modo Energy's policy is to pay top of personal market - if you're exceptional, we'll make it work.
• Modo Energy is an equal opportunity employer. Employment decisions are made on the basis of qualifications, merit, and business need. We do not discriminate on the basis of age, national origin, physical or mental disability, race, religion, pregnancy, sexual orientation, gender identity, veteran status, or any other characteristic protected under applicable UK law, including the Equality Act 2010.
