About Us

Avvoka is a fast-growing legal technology scale-up specialising in document automation. Our platform empowers legal, commercial, and operations teams to draft, negotiate, and manage contracts more efficiently - reducing friction, improving compliance, and accelerating deal cycles.

We’re trusted by leading global organisations, from Magic Circle law firms to major financial institutions and international franchises. Our technology has supported everything from billion-pound transactions to cross-border partnership agreements.

Avvoka is in an exciting growth phase - evolving from a bootstrapped start-up to a scale-up, with 60% growth in headcount and over 70% organic revenue growth in the past year.

Who You Are

You are a highly experienced and technically strong JavaScript/TypeScript developer who thrives on solving complex problems and building scalable, performant interfaces. You're someone who enjoys working on the "hard stuff"—optimising virtual editors, real-time collaboration, and low-latency rendering—while helping shape the future of how legal documents are created and interacted with.

You have a deep understanding of modern web technologies and engineering best practices, and you're comfortable taking ownership of sophisticated architecture and UI challenges. You’ll work in a cross-functional team alongside other developers, designers, and legal engineers to build and scale our document editor—one of the core parts of the Avvoka platform.

Key Responsibilities

1. Contribute to and Evolve the Editor

• Collaborate on development and architectural decisions for our in-browser document editor

• Build high-performance, low-latency features that handle complex data models and dynamic content

• Ensure compatibility across browsers and responsiveness across devices

2. Write and Maintain Robust Code

• Deliver clean, maintainable, and testable TypeScript/JavaScript code

• Work with modern frameworks and tools to continuously improve performance and stability

• Build for resilience, scale, and security in a B2B SaaS environment

3. Collaborate and Communicate

• Collaborate with product managers, designers, and other developers to deliver high-impact features

• Provide thoughtful code reviews and technical guidance to team members

• Contribute to discussions on UI/UX, performance, accessibility, and system design

4. Improve Developer Experience

• Identify and implement improvements to our internal development tools and pipelines

• Support documentation and onboarding for fellow engineers

• Share knowledge through internal demos, code walkthroughs, and paired programming

5. Drive Technical Excellence

• Stay up to date with latest best practices and advancements in frontend engineering

• Champion scalable design patterns, testing strategies, and CI/CD workflows

• Lead by example, setting a high technical bar for others to follow

Key Measures of Success

To ensure your application has the best opportunity of success, your CV could cover the below measures of success with quantifiable results (e.g. percentages, growth, reductions, impact)

• Editor Performance: You’ve improved editor load times, rendering speed, or real-time collaboration latency by measurable margins.

• Code Quality & Reliability: You consistently deliver clean, testable, and production-ready code with minimal defects or regressions.

• Feature Delivery: You’ve shipped impactful, user-facing editor features that enhance document creation and usability.

• Collaboration & Mentorship: You contribute to stronger engineering culture through thoughtful code reviews, pair programming, and technical guidance.

• Scalability & Architecture: You’ve implemented design patterns or architectural improvements that make the editor more robust, scalable, and maintainable over time.

Person Specification

The ideal candidate would have:

• Strong proficiency in JavaScript and TypeScript (minimum 5 years’ experience)

• Deep experience working with complex web applications, ideally involving content editors or design tools

• Strong grasp of browser internals, rendering performance, and memory management

• Prior experience working with collaborative or real-time features (e.g., OT, CRDTs, WebSockets)

• Solid understanding of testing strategies and performance monitoring

The desirable candidate would have:

• Experience with Slate.js, ProseMirror, or other rich-text editors

• Familiarity with legal tech, document automation, or similar B2B SaaS platforms

• Prior involvement in scaling frontend architecture in a growing startup or scale-up

• Exposure to ClojureScript or other functional programming paradigms

In addition to the technical and professional skills, there are certain core attributes we value across all roles:

• Adaptability in dynamically evolving settings

• A proactive, solution-focused mindset with ownership

• A collaborative spirit, supporting and mentoring others

If you’re excited about this role but your experience doesn’t align perfectly with every qualification, we encourage you to apply anyway — you might be just the candidate we’re looking for.

Our Hiring Process

• CV Review: Our People team reviews all applications carefully.

• Screening Call (15m): A quick virtual chat with our People team to learn more about you and answer any initial questions.

• Stage 1 – Assessment Interview (30–45m): A virtual assessment interview with the Hiring Manager focused on your experience and approach.

• Stage 2 – Senior Interview (for senior roles): An additional conversation with members of the leadership team.

• Meet the Team: Where possible, we’ll invite shortlisted candidates to visit our WeWork Waterloo office to meet the wider team.

We aim to make an offer to the successful candidate within a month of application, but this will vary by role and seniority.

Why Join Us

At Avvoka, you’ll join a considerate, innovative, and inclusive team where every voice matters. You’ll be instrumental in shaping our expansion into financial services - helping major institutions modernise how they handle legal and commercial documentation - while advancing your own career in enterprise SaaS sales.
