Senior Software Engineer

Location: Fully remote · GMT to GMT+3
Team: Product Engineering
Type: Full-time · Individual contributor
Salary: €/£80,000–110,000 per year (flexible depending on location and experience)

GoGlobal is a privately-owned global workforce solutions company operating across 180+ countries. We help organisations hire, pay, manage, and remain compliant wherever their people are — spanning Employer of Record, multi-country payroll, HR services, global recruitment, and international expansion consulting.

The engineering problems we face are genuinely hard: multi-jurisdiction payroll rules, real-time compliance enforcement, HRIS integrations at scale, FX handling across dozens of currencies. The work matters. Your code affects how people get hired and paid across the world.

• High-ownership work from day one. A focused team, a serious roadmap, and the expectation that you influence technical direction — not just execute tickets.
• A modern, opinionated stack. TypeScript end-to-end, with Effect for the service layer. We take type safety and composability seriously. If you've been waiting for a production codebase that actually uses functional patterns, this is it.
• A technically interesting immediate focus. You'll be leading work on a large API-first platform revamp — a greenfield opportunity within a live product.
• AI is a first-class part of how we work. We use AI to extend engineering capacity, and we hire engineers who use it daily and use it well. Our hiring process even includes a live AI-assisted coding interview — we want to see how you think with these tools, not whether you can memorise algorithms without them.
• Competitive salary. €/£80,000–110,000 per year, flexible depending on location and experience. No degree required — experience is what matters.

We're hiring a Senior Software Engineer to join the Product Engineering team. This is an individual contributor role — no people management. You'll design, architect, and ship. You'll influence technical direction, raise the bar through code review and mentorship, and own complex features end-to-end.

The immediate focus is a large API-first platform revamp. You'll have a say in how it's shaped.

• Architect and deliver the API-first platform revamp — defining service boundaries, API contracts, and data models
• Drive technical design reviews and establish engineering best practices
• Own end-to-end delivery of complex features across payroll, compliance, and HR product surfaces
• Improve CI/CD pipelines (GitHub Actions, ArgoCD), testing strategies, and deployment processes
• Mentor engineers through code reviews and pair programming
• Contribute to the technical roadmap and product strategy
• Build and iterate on AI-assisted workflows as agentic tooling becomes part of how we ship

• Language: TypeScript (functional style, frontend and backend)
• Frontend: React, Next.js
• Backend: Fastify, Drizzle, Effect
• Database: PostgreSQL, Redis
• Infrastructure: Kubernetes
• CI/CD: GitHub Actions, ArgoCD
• Observability: Grafana, Prometheus, Tempo, Loki

• 2-week sprints
• Fully remote, GMT to GMT+3
• Sync communication on Discord
• Small, senior-leaning team where your opinions shape how we build

Four stages, no surprises:

1. Recruiter call — Get to know each other, clarify the process. If it's a mutual fit, you'll receive an interview guide to prepare.
2. Hiring manager interview — Meet your potential leader, discuss your experience and approach.
3. System design interview — We observe how you think architecturally. No trick questions — we want to see your reasoning.
4. Coding with AI interview — You'll work in an environment with Claude Code. No prior Claude experience needed. We would like to see how you use AI as a thinking and delivery tool — not test your ability to code in a vacuum.

Required:

• Based between GMT and GMT+3
• 5+ years of experience at Senior level or above
• Expert-level TypeScript — large-scale production applications, not just familiarity
• Strong software architecture fundamentals — patterns, trade-offs, and the judgement to apply them
• Deep understanding of API design and best practices
• Production experience with PostgreSQL, Kubernetes, and Redis
• Experience in a mid-to-large engineering organisation (50+ developers)
• Active daily use of AI coding tools — this is a hard requirement, not a nice-to-have

Nice to have:

• Experience with Effect-ts or similar functional libraries
• Fastify
• Next.js
• Grafana stack (Prometheus, Tempo, Loki)
• Domain experience in HR tech, payroll, compliance, or regulated industries
