Job Summary
We are looking for a motivated and experienced Senior Software Engineer to join our AI Transformation team. This team will build AI-powered solutions for internal teams across Go-to-Market, Support, and the broader corporate side of Payscale—automating workflows, surfacing insights, and ultimately building toward a self-serve platform that enables stakeholders to solve their own problems at scale. This team will play an integral part helping to lead AI transformation from the ground up. You'll work across the entire stack—front-end interfaces, back-end services, and agentic AI systems—using modern technologies and an agent-first development approach. You will partner directly with internal stakeholders to understand their needs, prototype rapidly, and deliver secure, scalable solutions that compound in value across the organization, all the while building towards a scalable platform to empower and drive innovation at the edges of the broader organization through self service capabilities and solution management.

What You'll Do
As a
Senior Software Engineer
, your day-to-day responsibilities may include:

  • Own and build AI-powered applications end-to-end—from spec-driven design and implementation through deployment and production operation—with an eye toward generalizing solutions into reusable platform components.
  • Take responsibility for cloud infrastructure, CI/CD pipelines, monitoring, and production readiness, with support from the DevOps team when needed.
  • Develop and maintain user interfaces using React.
  • Build and consume REST APIs using Node.js with TypeScript.
  • Architect data models and access patterns, and efficiently consuming data from existing data-processing services and relational databases (AWS Aurora).
  • Iterating quickly on early-stage features, balancing speed of exploration with engineering quality.
  • Actively leverage agentic development tools (Cursor, Claude Code, etc.) across the full SDLC—from spec-driven design and code generation to testing, documentation, and deployment—continuously optimizing workflows for speed, quality, and token efficiency.
  • Design, build, and orchestrate agentic AI workflows and multi-agent systems that automate complex processes, progressively generalizing solutions into reusable components that enable stakeholders to self-serve.
  • Proactively identify and address technical debt, architectural risks, and scalability bottlenecks.
  • Drive quality end-to-end—leveraging (and building where necessary) agentic QA systems that continuously validate features and catch regressions, complemented by unit tests, integration tests, and strong engineering standards.
  • Debugging issues systematically across the full stack, including live production environments.
  • Collaborate closely with product managers, designers, and engineers while also partnering directly with stakeholders—acting as a consultant who distills requirements, validates solutions through rapid prototyping, and iterates based on real user feedback.

What We're Looking For

  • Strong problem-solving and critical thinking skills.
  • 5+ years of experience building backend systems with Node.js and TypeScript.
  • 5+ years of experience with modern front-end frameworks, specifically React.
  • Strong experience with microservices and service-oriented architectures.
  • Strong understanding of data model architecture and access patterns for data-intensive applications.
  • Solid experience working with complex relational databases — comfortable navigating non-trivial schemas, writing efficient queries, and reasoning about data relationships.
  • Comfortable working in a mixed environment — maintaining and evolving established products while also building new services and capabilities on top of them.
  • Good understanding of cloud infrastructure, CI/CD pipelines, and production operations — enough to work effectively alongside a DevOps team without needing hand-holding.
  • Experience with Docker and container orchestration (ECS, EKS, or Kubernetes).
  • A proven track record of writing clean, testable, and maintainable code.
  • Fluent (or actively progressing) in agentic development—you understand how to prompt and plan with AI agents using techniques like spec-driven design, know how to steer and course-correct agent behavior, and have experience creating and managing multi-agent workflows.
  • Hands-on experience with agentic development tools such as Cursor or Claude Code, with a working understanding of how to optimize token usage and maximize output quality.
  • Comfortable owning the full SDLC end-to-end—from requirements gathering through deployment and production operations—including building agentic QA systems to maintain quality at speed.
  • Strong consultant mindset with experience working directly with business stakeholders and internal customers—able to listen deeply, distill ambiguous requirements into actionable specs, validate ideas through rapid iteration, and adjust course based on feedback.

Nice to Have

  • Experience building AI-powered internal tools, self-serve platforms, or automation that enables non-technical stakeholders to solve their own problems.
  • Experience with prompt engineering, RAG architectures, or LLM orchestration frameworks (e.g., LangChain, LangGraph, CrewAI).
  • Familiarity with platform engineering patterns—designing APIs, abstractions, and interfaces that allow non-engineers to configure and extend functionality.
  • Awareness of UI/UX best practices and accessibility standards (e.g., WCAG).

Role description

N-iX
is a global software development company founded in 2002, connecting over 2,400+ tech professionals across 40+ countries. We deliver innovative technology solutions in cloud computing, data analytics, AI, embedded software,IoT, and more to global industry leaders and Fortune 500 companies. Join us to create technology that drives real change for businesses and people across the world.

Our client
is a fast-growing European fintech company in the business spend management space — corporate cards and related financial products — serving SME and mid-sized business customers across the EU and UK, in a regulated environment with GDPR compliance obligations. Engineering is organized into cross-functional squads, with platform/enabling teams providing shared tooling horizontally. The client already runs an AI-native engineering practice: Claude Code and GitHub Copilot are used daily, supported by a growing library of shared, versioned Skills embedded in key repositories, enabling an end-to-end flow from ticket to implementation, testing and PR in several codebases. AI tool/connector rollout follows an approved-list and pilot process. The client is AWS-first overall; for data platform and analytics workloads it also runs GCP, with BigQuery as the primary data warehouse. Day-to-day coordination is Slack-first, with Linear for ticket tracking, GitHub for code/PR review, and Notion as the knowledge base.

The client is also building out its AI platform and agentic capabilities: it recently launched an MCP surface in closed beta, giving external AI assistants a structured way to connect and perform real workflows behind guardrails, and treats agent reliability as a system property (tool contracts, approval/consent gates for write actions, evaluation harnesses).

We're looking for
a Senior AI Platform Enginee
r to design, build and operate the shared GenAI infrastructure that product teams rely on.

Key Responsibilities:

  • Design, build and operate shared GenAI infrastructure: LLM routing, vector search and RAG infrastructure, MCP gateway, and AI observability/evaluation tooling.
  • Apply strong distributed-systems fundamentals: async workflows, idempotency, failure design.
  • Work hands-on with LLM APIs in production.
  • Apply an AI-security mindset: prompt injection defenses, PII-in-logs handling, credential handling.
  • Apply real engineering rigor to the Context Development Lifecycle (CDLC): generate, evaluate, distribute and observe the context that powers AI agents.
  • Multiply the output and quality of the squad you join, and share patterns/practice beyond your immediate team so adoption compounds across the organisation.
  • Embed directly into a client squad as a hands-on Individual Contributor (not a coaching/managerial role).

Must-Have Skills:

  • Kotlin or Python as primary proficiency, with comfort contributing to both.
  • Experience designing/building/operating shared GenAI infrastructure: LLM routing; vector search and RAG infrastructure; MCP gateway; AI observability and evaluation tooling.
  • Strong distributed-systems fundamentals: async workflows, idempotency, failure design.
  • Hands-on production experience with LLM APIs.
  • AI-security mindset: prompt injection, PII in logs, credential handling.
  • Agent & harness engineering fluency, with concrete evidence of building/operating this kind of tooling, not just using it.
  • Comfortable with the client's current daily tools: Claude Code and GitHub Copilot.

Nice-to-Have Skills:

  • Specific cloud depth (AWS and/or GCP), Grafana, or named LLM API vendors. The RFP describes these capabilities generically rather than naming specific tools for this role — listed here as plausible, not confirmed.

We offer*:

  • Flexible working format - remote, office-based or flexible
  • A competitive salary and good compensation package
  • Personalized career growth
  • Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)
  • Active tech communities with regular knowledge sharing
  • Education reimbursement
  • Memorable anniversary presents
  • Corporate events and team buildings
  • Other location-specific benefits
  • not applicable for freelancers
