About the company

Our client builds an AI platform that enables enterprises to customize and deploy AI capabilities for their specific needs. The platform team is central to this work, responsible for infrastructure, shared components, and internal tooling that the rest of engineering depends on.

The role

This is a hands-on implementation engineering position. You'll work on deploying, configuring, and integrating the platform for enterprise clients, translating their requirements into working solutions, deployed at client's infrastructures. The role sits between product engineering and customer success: technically deep, but with awareness of real-world client needs.

You'll collaborate closely with platform engineers and business teams, occasionally joining business discussions to clarify technical requirements or explain implementation details.

What you'll work on

Implementing and configuring platform deployments for enterprise customers
Building integrations between the platform and client systems
Working with internal teams to understand client requirements and translate them into technical solutions
Contributing to implementation tooling, documentation, and repeatable deployment processes
Troubleshooting and resolving issues during and after deployment
Occasionally participating in client calls to gather requirements or provide technical guidance

What we're looking for

Strong proficiency in Node.js and TypeScript
Experience with React and frontend integration
PostgreSQL/similar RDBMS and general data modeling knowledge
Familiarity with cloud platforms (AWS, Azure, or GCP), multi-cloud exposure is valuable
Clear communication skills, - comfortable explaining technical concepts to non-technical stakeholders
Ability to work independently and manage multiple implementation workstreams
5+ years of software engineering experience

Useful additions / nice to haves

Experience with AI platforms or AI/LLM integration
Familiarity with CI/CD pipelines and infrastructure-as-code
Vue.js experience
Background in enterprise software implementation or professional services
Previous work in similar roles

Extra Nice to haves

Prize-winning places at programming olympiads (IOI, ICPC, Google Code Jam, Facebook Hacker Cup) or regional competitions.
High rating on coding platforms: LeetCode (Knight+ or 2000+ rating), HackerRank (Gold+), Codeforces (Expert+ or 1900+ rating).
Participation in hackathons with a focus on algorithmic problems (for example, victories at HackMIT, AngelHack).
