AI Backend Engineer

Fundo.one

is an

AI‑powered financing‑access platform

built to transform how SMEs secure the capital they need to grow. With a uniquely compelling product, an exceptional founding team, a vast addressable market, and strong backing, we’re positioned for something big.

Join us in

Genoa

at a moment when the AI revolution is redefining how the world builds, learns, and creates. We’re a fast‑moving startup driven by high standards, deep curiosity, and a culture that brings out the best in each of us.

Here, you won’t just write code,

you’ll craft end‑to‑end agentic AI products

, take genuine

ownership

, and experience the excitement of building something bold from the ground up. If you thrive where excellence, commitment, and ambitious thinking intersect, you’ll feel right at home with us.

We’re building a production

LLM-driven product

(with an MVP already proven) that helps organizations identify, prioritize, and write competitive grant applications. You’ll help design, implement, and operate the backend systems that power the LLM, retrieval, data pipelines, and evaluation — turning research into a reliable, secure, and scalable product.

Your role

Design, build, and operate the backend systems

that serve the Grant Optimizer LLM: model hosting, prompt orchestration, RAG pipelines, embeddings store, and inference APIs. Productionize fine-tuning and continual learning workflows

(supervised fine-tuning, LoRA/QLoRA, and RLHF, where applicable) and automate dataset curation based on user interactions and labeled outcomes. Implement retrieval

(vector database, chunking, metadata, MMR) and document ingestion pipelines for large collections of grant calls, program rules, and applicant documents. Build robust evaluation pipelines

(including automated metrics, human-in-the-loop feedback, and A/B testing) to measure relevance, factuality, and success in improving grant quality/award probability. Ensure privacy, compliance, and data governance

for sensitive grant documents (PII redaction, encryption, access controls). Optimise cost/performance for inference

(batching, quantization, multi-GPU orchestration, autoscaling). Collaborate with product, research, and frontend teams

to translate user workflows (scoring, ranking, drafting, suggestions) into reliable APIs and event processing. Create monitoring, alerting, and observability for model performance

, data drift, latency, and error budgets. Produce clear docs, runbooks,

and onboard engineers to the LLM backend.

Responsibilities

Implement inference services

(fast REST/gRPC endpoints) for generation and ranking. Build and maintain ETL pipelines

for ingesting grant notices, historical bids, scoring outcomes, and user documents. Manage embeddings pipeline:

text chunking, embedding generation, index creation and maintenance (FAISS / Pinecone / Weaviate / etc.). Automate SFT/finetuning and evaluation workflows

(training infra + dataset versioning). Apply retrieval-augmented generation techniques

and ensure timely, accurate retrieval with provenance. Implement rate-limiting

, request validation, caching layers, and cost controls for external LLM providers and self-hosted models. Run experiments to optimize prompts

, system messages, and chain-of-thought strategies for grant drafting tasks. Lead security reviews

and implement access controls, secure token handling, and audit logging.

Technical Must-have

Strong Python proficiency and experience building backend services (Flask/FastAPI, async frameworks). 3+ years building ML systems in production

; proven experience with LLMs in production (Hugging Face, OpenAI, Anthropic, or self-hosted). Practical experience with

retrieval systems and vector search

(FAISS, Milvus, Pinecone, Weaviate, etc.). Experience with model

fine-tuning workflows

(LoRA/QLoRA/SFT), dataset management, and training infra. Cloud experience:

deploying and operating services on AWS / GCP / Azure (Kubernetes, ECS, IAM, S3, Cloud SQL, etc.). LLM tooling

: Hugging Face Transformers, PEFT/LoRA, OpenAI API (or other hosted providers), LangChain/LlamaIndex. Familiar with

model optimization technique

s (quantization, batching, sharding) and cost/perf tradeoffs. Strong engineering practices

: testing, CI/CD, infra as code, MLOps (MLFlow), monitoring/observability (Prometheus/Grafana, Sentry, ELK/Cloud Logging).

Background must-have

English proficiency:

C1 level or higher

, with the ability to work and communicate daily with an international team. Teamwork: You enjoy

collaborating in cross-functional teams

and contributing to shared goals. Startup mindset

: You’re comfortable in a fast-paced startup environment, take ownership, and adapt quickly to change. Education:

Bachelor’s or Master’s degree in Computer Science, Engineering

, or related fields.

Nice-to-have

Familiarity with LangChain, LlamaIndex, or similar orchestration libs and prompt engineering best practices. Background in ML evaluation (factuality metrics, BLEU/ROUGE useful but also human eval design). Experience with private

LLM deployment

(tuned LLaMA derivatives, Mistral, etc.) and GPU orchestration. Experience with

data privacy, GDPR,

and secure handling of sensitive documents.

Offices

The office in Via del Molo 65r, Blue District, Genova. Work model:

Hybrid working

, combining office presence and remote work.

Working at Fundo.one means joining an

early-stage startup

where your work has a real, visible impact. You’ll collaborate closely with the founders, move fast, take ownership, and help shape both the product and the company from the ground up.
