AI Engineer, Backend Systems Founding Team Location: Delhi Employment type: Full-time Reports to: Founder and CTO About Delphic AI is changing how businesses discover, evaluate and engage with expert knowledge. Delphic works with knowledge-led businesses navigating this shift while protecting the value of their proprietary expertise. We are building the technical infrastructure needed to make complex, evidence-sensitive AI workflows reliable, measurable and useful in production. We are hiring an AI Engineer to help build Delphics core backend systems. You will work at the intersection of large language models, retrieval, evaluation, workflow orchestration and production software engineering. This is an opportunity to shape an AI system from an early stage, work directly with the Founder and CTO, and take meaningful ownership of the technical architecture. The role You will design, build and operate production backend systems for data-intensive AI workflows. The technical challenge goes well beyond producing a plausible model response. Our systems must remain reliable when models are non-deterministic, external services change, data is incomplete and outputs require evaluation or human judgement. You will work across backend services, data systems, model integrations, evaluations and infrastructure. You should be comfortable moving between system design, implementation, debugging and production operations. This is an applied AI engineering rolenot a prompt-only, frontend or foundation-model research position. What you will do Design and build scalable backend services and APIs for AI-powered products and internal systems. Build and improve reliable production AI workflows and the backend services that support them. Create robust evaluation frameworks for non-deterministic AI outputs. Develop automated tests, regression suites and representative evaluation datasets. Build observability for model behaviour, system performance, costs, failures and data quality. Design clear data models and interfaces between AI components and conventional software systems. Engineer for retries, idempotency, rate limits, partial failures and changing external dependencies.Improve the accuracy, latency, throughput and cost of production AI workflows. Implement appropriate security and data-isolation controls for customer information. Evaluate new models, tools and infrastructure based on measurable improvements rather than novelty. Work closely with the Founder and CTO on technical priorities, architecture and product decisions. Help establish the engineering practices and technical standards of the early team. You may be a strong fit if You have strong software engineering skills and experience shipping production AI systems. You have hands-on experience with LLMs, agents, evaluations, RAG, tool-calling or AI workflow orchestration. You are strong in Python and comfortable building maintainable backend services. You have experience working with SQL databases, APIs, data models and asynchronous workflows. You understand testing, deployment, monitoring and production debugging. You know that a convincing AI demo and a dependable AI product are very different things. You can design ways to evaluate AI behaviour rather than relying only on subjective inspection. You are comfortable investigating failures across application code, model behaviour, data and infrastructure. You can make thoughtful trade-offs between correctness, latency, cost and engineering complexity. You have a strong ownership mindset and can operate effectively in a fast-moving, early-stage environment. You communicate technical decisions, uncertainties and trade-offs clearly. You are comfortable working with evolving requirements and taking a problem from initial definition through production operation. We care more about what you have built, shipped and learned than your degree or current job title. Useful experience Experience in some of the following areas would be valuable, but we do not expect every candidate to have worked with all of them: Python backend frameworksPostgreSQL and data modellingCloud infrastructure and containerised deploymentsQueues, background jobs and durable workflow systemsModel APIs and multi-model applicationsRetrieval systems, embeddings, ranking or vector searchAgent frameworks and tool integrationStructured model outputsAI evaluation and observability platformsSecurity and data isolation in multi-customer systemsTypeScript or full-stack collaboration What success looks like In your first few months, you will: Develop a strong understanding of Delphics existing systems and technical priorities.Take ownership of meaningful parts of the backend and AI infrastructure.Ship improvements to system reliability, evaluation, observability or performance.Turn experimental workflows into maintainable production services.Reduce
Here's how to pick the right one and stand out in your application.
144.883Jobs
31.687IN
81%EN
That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
