Node.js TypeScript

Podsumowanie oferty

Build production AI agents and agent-facing tools as part of a cross-functional development team. The role uses TypeScript, AWS, React, and AI frameworks and SDKs to develop agent services, integrations, and internal tooling.

Wymagania

Broad technical perspective and adaptability across modern software stacks and architectures, favoring breadth and quick ramp-up over narrow specialization.
Strong production experience with modern React and TypeScript, including Node.js, async patterns, testing, and monorepo tooling.
Working proficiency with Python for backend services, evaluations, analysis, and automation tooling.
Practical hands-on experience across the AWS ecosystem, including serverless services such as Lambda, Step Functions, DynamoDB, and Bedrock, as well as containers (ECS/EKS), networking, compute, and IAM.
Experience shipping features that leverage LLM APIs (prompts, tool calling, structured output, long context), and describing the evaluation that gated release, what failed, and what changed.
Enthusiasm for using AI-assisted engineering tools in daily workflows (e.g. Copilot, Cursor, LLM APIs) and championing AI-first practices and productivity across the team.
Ability to read and safely modify Terraform configurations across environments.
Hands-on experience with both NoSQL and SQL stores, including schema changes and live-system migrations.
Ability to design metrics, logs, and alarms for non-deterministic systems and debug production issues using them.
Proficiency with modern CI/CD pipelines, ideally GitLab CI/CD.
Fluent written and spoken English, with the ability to articulate trade-offs clearly and align team members around technical decisions.

Nice to have:

Experience with multi-agent systems, MCP servers, or evaluation frameworks.
LLM cost control, including model routing, prompt caching, and token budgets.
Prompt-injection defense and agent security.
GraphQL for internal APIs and tooling.
Code intelligence or retrieval work, such as indexing, symbol search, and knowledge bundles.
Kubernetes, AWS AppSync, and EventBridge.
Playwright/Cucumber test automation.
Claude Certified Developer or Claude Certified Architect (Anthropic).

Obowiązki

Build production AI agents by developing TypeScript services on AWS using Lambda, Step Functions, DynamoDB, Bedrock, Strands or LangGraph, and AI SDKs.
Design agent behavior by defining what the model investigates and what code enforces.
Build agent sandboxes with read-only runtimes, scoped tool access, worktree-contained reads, and budget and timeout guards.
Evaluate AI features using golden sets and production replays; calibrate judges; gate changes on recall, precision, and false-positive rate; and compare models and effort levels before release.
Emit reason-coded metrics and structured logs, set alerts on failures, and investigate production misses in Splunk and VictoriaMetrics.
Maintain Terraform roots across environments under tagging and permission-boundary rules; improve GitLab CI/CD for build, test, deploy, and quality gates.
Build integrations resilient to retries, rate limits, permanent failures, and stale state.
Use AI to write and review code, and keep agent context current.
Review AI-written changes for security, correctness, and maintainability, catching issues tests miss.
Configure assistants, skills, hooks, and MCP servers; pair with engineers and share proven practices.
Build agent-facing tools using React and APIs for summaries, dashboards, and internal tooling, with outputs readable by agents, CLIs, and Slack.
Document systems with architecture and sequence diagrams, runbooks, and decision records.
