AI Backend Engineer (AI Workflow Systems) in London

BJAK is Southeast Asia's largest digital insurance platform, building AI-powered products that simplify insurance and financial services for millions of users. We use AI and automation to transform real-world insurance workflows such as quotations, policy issuance, endorsements, claims, and customer follow-ups.

We are looking for talented AI Backend Engineers to build the systems that power AI-driven decisioning, automation, and orchestration across our platform. This role sits at the core of our AI stack – between models, backend systems, and real users – where latency, correctness, reliability, and cost directly impact production experience. This is a fully remote position where you will be part of a global engineering team working across multiple countries to build reliable, scalable AI systems.

Focus

• Build and operate backend systems that serve AI-powered insurance workflows in production.
• Design and implement AI orchestration layers that connect models, APIs, workflows, and business logic.
• Build inference pipelines for LLM-based and AI-assisted automation systems.
• Optimize latency, throughput, and cost across AI services (caching, batching, streaming, routing).
• Design stable service boundaries between backend systems, ML components, and product APIs.
• Implement observability: logging, metrics, tracing, alerting, and incident response workflows.
• Debug production issues across distributed AI systems and resolve root causes.
• Collaborate closely with frontend, product, operations, and ML teams to ship end-to-end features.
• Continuously improve system reliability, scalability, and performance.

Ideal Experience

• Strong backend engineering experience in production systems.
• Experience building or operating high-throughput, low-latency services.
• Familiarity with AI systems (LLMs, embeddings, or AI workflows).
• Experience with distributed systems and production debugging.
• Strong understanding of APIs, data flows, and system design principles.
• Experience with observability tools (logging, monitoring, tracing).
• Strong ownership mindset and bias toward shipping.
• Comfortable working in fast-paced, globally distributed teams.

Outcomes

• AI backend systems run reliably at scale with low latency and high availability.
• AI workflows are stable, observable, and production-ready across multiple products.
• System performance improves continuously through real-world feedback and optimization.
• Production incidents are quickly detected, diagnosed, and resolved.
• AI capabilities are seamlessly integrated into global customer and internal workflows.

Tech Stack

• Python
• Node.js
• LLM APIs (OpenAI / Anthropic / open-source models)
• SQL / NoSQL databases
• Kubernetes
• Docker
• Distributed systems tooling
• Observability stacks (logging, metrics, tracing)

How We Work

We believe strong products are built by small, high-ownership teams. Engineers at BJAK work closely with product, design, AI, and operations teams to solve meaningful real-world insurance problems. We value technical excellence, speed of execution, and practical decision-making. Engineers are expected to own systems end-to-end—from design and implementation to production reliability and iteration.

Why Join BJAK

• Build AI-powered Products – Work on intelligent insurance automation systems.
• Global Engineering Organization – Collaborate across multiple countries.
• International Impact – Products used by millions across Southeast Asia and beyond.
• Learning & Development Budget – Support for continuous growth.
• High Ownership Culture – End-to-end ownership of engineering systems.
• Modern Engineering Practices – Focus on scalability and reliability.
• Career Growth – Fast-moving engineering environment.
• Competitive Compensation – Attractive salary package.
• Fully Remote – Work remotely with globally distributed teams.

The Kind of Builder We Want

• Thinks in systems, not just services or endpoints.
• Strong ownership of production behavior and system outcomes.
• Comfortable working with ambiguity and evolving requirements.
• Strong attention to failure modes, latency, and reliability.
• Focused on real-world production impact over theoretical design.
• Moves fast while maintaining engineering discipline.
• Obsessed with making systems stable, observable, and scalable.

This Role Is Not For

• Engineers who only build features without owning production systems.
• Those uncomfortable debugging distributed systems under load.
• Developers who avoid responsibility for production incidents.
• Engineers who require perfect specifications before starting work.
• People who treat AI systems as black boxes without operational ownership.

Interview Process

If there appears to be a fit, we'll reach out to schedule 3, but no more than 4 interviews. Applications are evaluated by our technical team members. Interviews will be conducted via virtual meetings and/or onsite. We value transparency and efficiency in our hiring process and aim to make decisions promptly. If you've demonstrated the exceptional skills and mindset we're looking for, we'll extend an offer to join us. This isn't just a job offer; it's an invitation to be part of a team building AI systems that power real-world insurance workflows across global markets.
