Description

Nexl is looking for a Senior Full Stack Engineer who is technically rigorous, highly autonomous, and genuinely AI-first in how they build. Someone who uses AI agents, structured prompting, and automated workflows as their primary development mode, not as a layer on top of traditional engineering. You'll work within a cross-functional squad partnering closely with your Tech Lead, Product Manager, and shared Designer. The expectation is that you use AI to ship more, at higher quality, and faster than traditional engineering approaches allow. Deep fundamentals still matter: architecture, debugging, security, system thinking - because those are what allow you to direct AI effectively, make the decisions it cannot, and catch where it goes wrong. This is a high ownership role for someone who thrives working autonomously, holds a high bar for what they ship, and wants to help define what elite AI-first engineering looks like at a fast-growing LegalTech company. The right person will be equally comfortable discussing architecture trade-offs, code quality, AI tool selection, and the impact their work has on the product and the customer. * Design and ship features end-to-end across React/TypeScript and Ruby on Rails or Python — from problem definition through architecture, implementation, testing, and release. You own the outcome, not just the ticket. * Use Claude Code, Cursor, Devin, and similar agentic tools as a genuine development partner — structuring problems for AI execution, validating output, and maintaining architectural integrity across what gets shipped. * Build AI agents and automated workflows that multiply output across the squad — shared infrastructure that makes the whole team faster, not just your own velocity. * Make the design and trade-off decisions that AI cannot — system design, data modelling, security, technical debt, and long-term platform health. * Set and hold a high bar for AI-generated code — reviewing for correctness, security, performance, and long-term maintainability, not just whether it runs. * Own the reliability and scalability of what you ship — and use AI to do it faster. Better observability, cleaner architecture, fewer production incidents over time. * Work closely with your Tech Lead, Product Manager, and Design across every initiative — bringing technical depth, AI-native velocity, and a clear point of view on what to build and how. * Help the engineers around you raise their AI game. Share what works — the tools, the prompting approaches, the workflows — and make the whole team faster, not just yourself. Must haves: * Deep expertise in full-stack software architecture, system design, data modelling, debugging, and security. These fundamentals are non-negotiable — they're what let you direct AI effectively and catch what it gets wrong. * Strong proficiency in React + TypeScript and strong proficiency in Ruby on Rails or Python. * You have fundamentally changed how you build. You use Claude Code, Cursor, Devin, or equivalent agentic tools as your primary development workflow — and you can demonstrate meaningfully higher output velocity as a result. * Ability to critically assess AI-generated code for correctness, security, performance, and long-term maintainability. You know when to push back, refactor, or start over — and you do. * Experience designing and orchestrating multi-agent systems — decomposing work across autonomous agents, managing inter-agent communication, and ensuring reliable, observable outcomes at the system level. * Solid understanding of database design and optimisation (PostgreSQL, MongoDB) including indexing, query optimisation, and data modelling. * Ability to take ownership, operate with minimal direction, and drive outcomes end-to-end. * Understands security best practices and holds AI-generated code to the same rigorous standard as hand-written code. * High ownership and accountability mindset, with a strong bias toward impact over activity. Nice to haves: * Experience with GraphQL, gRPC, or real-time communication protocols (WebSockets). * Experience in multi-tenant, data-heavy SaaS applications. * Familiarity with Marketing Tech, CRM-like systems, or workflow automation products. * Knowledge of DevOps practices, Infrastructure as Code, or cloud infrastructure (AWS or Azure). * Experience in LegalTech or Professional Services tech. What Success Looks Like: * You ship features at significantly higher velocity than traditional engineering workflows, and the quality and reliability of what you ship is high. * AI agents and workflows you build are adopted by the squad, multiplying the team’s collective output — not just your own. * Architectural and trade-off decisions are yours and they’re sound: AI handles implementation; you own the judgment. * AI-generated code in the codebase passes the same bar as hand-written code for correctness, security, and long-term maintainability. * You help define what AI-first engineering looks like at Nexl, and other engineers want to learn from your workflow. * High growth. A scaling environment with autonomy, ownership, and visible impact. * ESOP. Employee stock options so you share in the upside. * Tools & tech. Modern, AI-first ways of working to help you move faster and smarter, plus a work laptop. * Birthday leave. Take a paid “Nexl Day” during the week of your birthday. * Transparent by default. Fortnightly all-hands with strategy, metrics, wins, and learnings. * Purposeful connection. Team offsites and meet-ups. * Values-led culture. Guided by The Nexler Way, our values and operating principles that define who we are, how we work, and how we win together. Our Values * Committed to Care - We genuinely care about the work we do and the industry we do it for * Human at the Core - Relationships and empathy guide everything we do * Different with Purpose – We’re not afraid to stand out. We innovate boldly and deliberately

Responsibilities

Design and ship end-to-end features using AI-first development workflows while maintaining high architectural and security standards. Collaborate with cross-functional teams to build shared AI infrastructure that multiplies the squad's overall velocity.
