Backend Engineer

AI Automation Specialist

Apilex

Istanbul

Apply on the employer's site

Role description

Apilex is an AI-native legal operating system that manages lawyers' entire legal workflows end to end, powered by AI systems purpose-built for each jurisdiction's legal framework. We bring legal research, drafting of pleadings and contracts, document analysis, and case preparation together in a single experience. We currently operate in France, Turkey, and Germany, and we aim to extend the growth we've achieved in our current markets to Brazil, Spain, and Italy.

We achieved this growth entirely bootstrapped, without raising any external investment, making us one of the fastest go-to-market success stories among Legal AI startups in the world. Since our founding, we've scaled our team to 120+ people, backed by a proprietary database of millions of court decisions and legal documents that turns days of legal research into seconds.

What sets us apart?
We don't use off-the-shelf AI. We build domain-specific, closed-circuit AI models with multi-layered verification systems that eliminate hallucinations and deliver answers backed by real citations and legal reasoning. Every feature we ship changes how lawyers work.

Every team at Apilex; Growth, Sales, Marketing, Customer Success, Product, Finance, and People spends countless hours on manual tasks that intelligent agents could handle faster and more consistently. From pre-call research and ticket triaging to chasing stale deals, these tasks aren't complex, but they eat away at high-value time.

We are building an
internal engineering team
to solve this. Rather than sitting in a central ticket queue taking automation requests, you will embed directly with business units, analyze real workflows, and build high-impact LLM-powered agents that return measurable hours to the company.

What you'll do

  • Embed & Discover:
    Sit with teams for weeks at a time, shadow their workflows, and identify high-leverage opportunities to automate manual work.
  • Build End-to-End:
    Design, build, deploy, monitor, and iterate on LLM-powered agents and integrations.
  • Integrate Systems:
    Connect our GTM and operational stack (CRM, support desk, data warehouse, internal tools) with models via robust APIs, webhooks, and data pipelines.
  • Build Foundations:
    Create shared infrastructure for the team, including credential management, observability, evaluation harnesses, and human-in-the-loop fallback layers.
  • Instrument & Measure:
    Ensure every agent ships with built-in tracking to evaluate performance, failure states, and overall system accuracy.
  • Own Outcomes:
    Drive business impact measured in hours returned and costs avoided—not just the quantity of workflows shipped.

What we're looking for

  • Workflow Automation & Orchestration (Core Focus): Deep hands-on expertise in building complex automation and orchestration pipelines (with extensive experience in tools like
    n8n
    , low-code/no-code platforms, and custom code) to rapidly connect systems, APIs, and business logic.
  • Expertise in structured outputs, function/tool calling, RAG, agent loops, and orchestration frameworks, paired with a pragmatic sense of knowing when
    not
    to use complex AI solutions.
  • Proven track record using Python or/and TypeScript, with experience owning critical backend services and scalable architectures.
  • Deep understanding of REST APIs, webhooks, auth flows, rate limits, and navigating third-party systems (CRMs, support desks, enrichment tools) to glue business tools together seamlessly.
  • Ability to build evaluation harnesses and test sets to prevent prompt regressions and ensure production reliability.
  • Familiarity with data engineering workflows (warehouses, pipelines) and compliance constraints (GDPR/KVKK) when handling customer data.
  • bility to interview non-engineers (sales reps, support leads) to diagnose root problems and translate them into technical and automated requirements.
  • Passion for shipping the simplest working solution—whether that’s a robust n8n workflow, an agent system, or 40 lines of code and a cron job.

Why join us?

Whatever your role, your work here will be visible and meaningful. We're a team that has grown without outside investment and achieved one of the fastest go-to-market successes in the space and we're looking for ambitious people who want to build the future of legal technology on a global stage. 

This is Apilex. AI for Legal. Join us
