Descripción del empleo

What Youll Do

As a Senior Software Engineer at InteractiveAI you’ll be at the center of delivering production-ready features, integrations, and client implementations that power our platform and enterprise deployments.

This is a hands‑on high‑ownership engineering role. You will architect, implement, and ship complex backend and frontend systems, building everything from internal tooling and workflow orchestration layers to customer‑facing interfaces and enterprise integrations.

You’ll collaborate closely with product, DevOps, and AI engineering teams to deliver high‑quality, scalable, and secure software in a fast‑moving environment.

Architect, implement, and maintain microservices and backend modules for our enterprise agent management platform.

• Build full‑stack features and internal tools using TypeScript, React, and modern UI frameworks
• Design and integrate RESTful / GraphQL APIs, 3rd‑party SaaS services, authentication systems, and enterprise connectors
• Deploy and manage containerized services on AWS, GCP, or Azure with Docker and Kubernetes
• Define and maintain Terraform modules and IaC workflows for networking, compute, and storage
• Build and optimize data ingestion, transformations, and caching layers using Postgres, Redis, and/or ClickHouse
• Collaborate with DevOps on CI/CD pipelines, release processes, and environment automation
• Implement observability tooling (logging, metrics, alerting) to ensure reliability and performance
• Work directly with delivery teams to ship client‑facing integrations, connectors, and application flows
• Take full ownership of features from design to production, including testing, documentation, and rollout

What We’re Looking For

We’re looking for a top‑tier full‑stack engineer with strong foundations, excellent execution, and the ability to ship high‑quality software quickly. You should excel at building production systems and integrations even in ambiguous or fast‑changing environments.

Minimum Requirements

• 5 years professional experience building and deploying full‑stack or backend‑heavy web applications
• Strong experience with TypeScript, React, and modern frontend frameworks
• Solid backend engineering experience with Python or similar languages
• Hands‑on experience with Docker, containerized services, and Kubernetes
• Strong proficiency with relational and/or analytical databases (Postgres, Redis, ClickHouse, etc.)
• Experience designing and consuming RESTful and/or GraphQL APIs
• Practical experience deploying workloads to AWS, GCP, or Azure
• Familiarity with Infrastructure as Code (Terraform preferred)
• Solid understanding of CI/CD, automated testing, and release engineering
• Excellent communication skills in English and strong ability to work cross‑functionally

Nice‑to‑Haves

• Experience building enterprise integrations (SAML / OAuth, HubSpot / Salesforce, data warehouses, messaging platforms, etc.)
• Familiarity with event‑driven architectures, message queues, and streaming systems
• Experience with system design at scale (multi‑tenant architectures, service boundaries, performance patterns)
• Contributions to open‑source or participation in engineering communities
• Exposure to AI/ML workflows is welcome but not required

What You’ll Get

• Competitive base salary ($70,000 / yr to $100,000 / yr) and performance bonuses
• Access to equity / share plan as it rolls out
• Health & wellness allowances
• Private health insurance
• Flexible work setup, travel when needed (ideally Hybrid in Lisbon or Madrid)
• 25 days of holidays / paid time off (excluding local public holidays)

Who You Are

• Proactive & Resourceful: You solve problems independently and take initiative without waiting for direction.
• High‑Ownership Engineer: You treat the codebase as your own and deliver with quality and urgency.
• Execution‑Driven: You thrive in a fast‑paced environment and enjoy shipping high‑impact features.
• Collaborative & Clear Communicator: You work effectively with product, DevOps, and engineering peers and you mentor others when needed.

Interview Process

We keep our process focused and respectful of your time. Most candidates complete it in 23 weeks. Here’s what to expect:

• Intro Call – 30 minutes to align on fit and expectations
• Take‑Home Challenge – A practical task based on real‑world product or engineering problems
• Technical Interview – Deep dive into software architecture, system design, and engineering experience
• Cultural and Values Interview – Discussion on motivation, working style, and value alignment

We’re forming a team of builders – people who care about impact, quality, and growth. If that’s you, let’s talk.
