Senior Backend Engineer – Automation & Platform Implementation
Requirements and responsibilities
Readable role content extracted into sections for faster review.
🧱 Platform Development & Backend Architecture
- Build, extend, and optimize Java-based microservices responsible for task execution, state management, and orchestration logic.
- Model and manage NoSQL document databases to track execution state, workflow metadata, and session/context persistence.
- Define internal API contracts, adapters, and connectors that enable modular integration with external APIs and customer deployments.
🧠 AI-Related Backend Engineering
- Implement production-ready infrastructure for data ingestion, document chunking, embedding indexing, and retrieval (RAG) pipelines.
- Architect backend services that support multi-step agentic flows, including context assembly, tool calls, and session memory.
- Turn product requirements for semantic search and AI assistant features into resilient, production-grade backend code.
🤖 Customer Implementation & Enablement (FDE Work)
- Deploy, configure, and customize the automation platform to meet specific customer use cases and business requirements.
- Connect external systems through custom sync pipelines, webhooks, and enterprise integrations (e.g., OAuth, ETL-style ingestion).
- Debug production issues across our stack and customer environments, capturing field insights to improve the core platform.
- Enhance platform observability by setting up robust tracing, execution visibility, and debugging tools for failed runs.
Core Backend Engineering
- 4–6 years of software engineering experience building resilient production backend systems and working with distributed architectures.
- Strong proficiency in Java, with deep experience developing scalable microservices, handling asynchronous jobs, retries, idempotency, and system failure modes.
- Experience with NoSQL document databases (e.g., MongoDB, Firestore, Couchbase) for state and metadata tracking.
Automation & AI-Aware System Experience
- Experience building or integrating workflow engines or enterprise automation systems (beyond one-off scripting).
- Working knowledge of Python for building integrations, tooling, and rapid prototyping.
- Solid understanding of LLM application structures, including embedding systems, vector search, retrieval mechanics, context windows, and agent/tool execution.
- Strong interest or hands-on experience in semantic search, RAG pipelines, or conversational AI backends.
Professional Execution & Mindset
- High Agency & Independent Execution: You have a strong sense of ownership and the exceptional self-direction required to navigate undocumented paths, make sound architectural calls, and take a project to completion with minimal guidance.
- Thrives in a Startup Environment: You are energized by a fast-paced, evolving startup environment, are comfortable when requirements pivot, and are explicitly not looking for a predictable, mature role at a big company.
- Wears Multiple Hats Comfortably: You gladly step outside a narrow engineering lane. You can context-switch seamlessly between core backend engineering, customer fire drills, and partner-facing implementation without losing quality.
- Customer-Facing Technical Experience: Proven ability to interface with product teams, solution architects, and customer stakeholders to translate vague user requirements into working, deployed software.
- Strong Documentation Culture: A consistent habit of writing clear system designs and deployment guides so that the next team member never has to start from zero.
Nice to haves
- Familiarity with durable execution systems or workflow engines (e.g., Temporal, Airflow, Camunda).
- Experience designing plugin, connector, or developer framework ecosystems.
- Understanding of Edge/serverless computing or Backend-for-Frontend (BFF) patterns for customer-facing apps.
