Backstage Developer information

What is a backstage developer?

Backstage Developers are software engineers who specialize in building, customizing, and maintaining developer portals using Backstage, an open-source platform created by Spotify. They help organizations organize their software infrastructure, integrate tools, and improve developer productivity by creating unified interfaces for internal services, documentation, and workflows. Their work often includes plugin development, API integration, and ensuring the platform meets the needs of engineering teams.

What are the key skills and qualifications needed to thrive as a backstage developer?

To thrive as a Backstage Developer, you need strong skills in JavaScript/TypeScript, experience with React, and familiarity with software development tools, along with a background in computer science or equivalent experience. Knowledge of Backstage’s framework, plugin development, CI/CD systems, and cloud platforms is typically required, and certifications in cloud services or DevOps can be advantageous. Excellent problem-solving, collaboration, and communication skills help you work effectively within cross-functional teams and deliver scalable developer portals. These abilities are crucial for building, customizing, and maintaining platforms that streamline internal developer workflows and improve productivity.

What are some of the main challenges backstage developers face when integrating new plugins into existing platforms?

Backstage Developers often encounter challenges related to plugin compatibility, documentation gaps, and ensuring seamless integration with diverse internal tools. Each organization may have a unique tech stack, so adapting plugins to work smoothly requires strong problem-solving skills and cross-team collaboration. Additionally, maintaining consistent user experience and managing version upgrades can be complex, especially as the platform evolves. Working closely with platform engineers and end users is key to overcoming these hurdles and delivering robust solutions.

What is the difference between Backstage Developer vs Frontend Developer?

AspectBackstage DeveloperFrontend Developer
Required SkillsJavaScript, React, APIs, DevOps toolsHTML, CSS, JavaScript, frameworks like React or Angular
Work EnvironmentDeveloping internal developer portals, tools, and integrationsBuilding user interfaces for websites and applications
Industry UsageTech companies, software development teamsWeb development agencies, tech firms, startups

Backstage Developers focus on creating developer portals and tools to improve internal workflows, often working with APIs and DevOps integrations. Frontend Developers primarily build the visual and interactive parts of websites and applications. While both roles require JavaScript and related skills, Backstage Developers specialize in developer experience platforms, whereas Frontend Developers focus on user-facing interfaces.

Can you actually get jobs on Backstage Developer?

Backstage Developer is a role focused on building and maintaining developer portals and internal tools using platforms like Backstage. Job opportunities for Backstage Developers are available in tech companies and organizations seeking to improve developer experience, often requiring skills in software development, DevOps, and familiarity with the Backstage platform. These roles typically involve collaboration with engineering teams and may require knowledge of programming languages and cloud environments.

Agentic AI Engineer (Agent SDK & Developer Enablement)

This job post has expired 2 days ago. Applications are no longer accepted.


Job description

Role:                    Agentic AI Engineer (Agent SDK & Developer Enablement)

Location:            Oaks, PA

 Duration :          12+ Months 

Exp. Required: 10+ years

Need candidate who can work onsite from Day 1 (Hybrid basis)

 

RESPONSIBILITIES

The platform is being designed as the engagement progresses, so responsibilities will evolve. Indicative, and not limited to:

  • Design and build the agent SDK across multiple languages, published to internal package registries, wiring model calls through the platform gateway together with tracing, identity, guardrails, and retrieval and memory interfaces.
  • Own the public interface of the SDK: API design, versioning and backward compatibility, deprecation strategy, and the release process teams depend on.
  • Build the SDK interfaces agents use for memory and retrieval: session and short-term conversation state, long-term memory, and retrieval against the enterprise knowledge sources, exposed so that an agent developer gets correct behaviour without hand-rolling their own integration.
  • Build the project scaffold that generates a compliant, runnable agent project, with the SDK pre-wired, configuration, container and deployment manifests, evaluation configuration and the pipeline already in place.

.

 

Skills Required:

·        3+ years hands-on agent or LLM application development, having personally built and shipped applications using agent frameworks or SDKs such as LangChain, LangGraph, the OpenAI Agents SDK, Microsoft Agent Framework, or equivalent. This is non-negotiable for this position.

·        6+ years professional software engineering, with production depth in at least two of C#, Python, Java and TypeScript or JavaScript, and the ability to work across all four. There is no one-language-per-engineer model on this team.

·        2+ years building automated testing or evaluation for LLM or agent applications, using frameworks such as the Azure AI Evaluation SDK, Promptfoo, DeepEval, Ragas, LangSmith evaluation or equivalent. This includes handling non-deterministic output, building golden datasets, and running evaluation as a gate inside CI rather than as a manual exercise.

·        2+ years working with agent memory and retrieval in application code: conversation and session state, short-term and long-term memory, and retrieval-augmented generation against a vector or search backend. You do not need to build the stores, but you must know what an agent developer needs from them and how these interfaces behave inside an agent loop.

·        3+ years designing and maintaining libraries or SDKs consumed by other engineering teams: public API design, versioning, backward compatibility, and packaging to registries such as NuGet, PyPI, Maven or npm.

·        3+ years building CI/CD pipelines using GitHub Actions, Azure DevOps or equivalent, including quality gates that block promotion.

·        2+ years working with LLM application patterns in production: tool and function calling, structured output, streaming, context management, retries and fallback across providers, and prompt handling.

·        Fluency with AI-assisted development tooling such as GitHub Copilot, Claude Code or Cursor, used daily as part of how you work. Team sizing on this engagement assumes that leverage.

·        2+ years working with containerised deployment and a major cloud platform, sufficient to build scaffolds that deploy cleanly into Kubernetes and managed runtimes.

·        Demonstrable developer experience judgement: building tooling, templates or libraries that other engineers adopted willingly, and iterating based on their feedback.

·        Working knowledge of OpenTelemetry and how tracing is instrumented inside a client library.

 

Preferred Skillset

·        Experience with red teaming or adversarial testing of LLM applications, including prompt injection and jailbreak testing.

·        Experience building internal developer platforms or paved-path tooling adopted across multiple engineering teams.

·        Model Context Protocol (MCP) server or tool integration.

·        Experience with project scaffolding or code generation tooling, such as Yeoman, Cookiecutter, Backstage software templates or equivalent.

·        Technical writing for engineering audiences, including documentation structured for consumption by AI coding tools.

·        Experience in financial services or another regulated industry, where governance is expected to be built into tooling rather than applied afterwards.

·        Exposure to Azure AI Foundry or comparable managed agent runtimes.
