Why This Role is Unique
This is a hands-on engineering role where you will:
- Design and build agents and AI workflows, including tool integration, orchestration, guardrails and human validation steps.
- Integrate LLMs, retrieval and classical ML or speech models with clients' existing systems and data.
- Make these solutions reliable in production through systematic evaluation, tracing, fallback strategies, and cost and latency control.
- Apply software engineering best practices: testing, CI/CD, modular design and documentation.
- Address the requirements of regulated industries, such as security, compliance, access control and integration with legacy systems.
- Own solutions end to end, from scoping with the client to production monitoring and continuous improvement.
- Work closely with vector8's engineers and project managers, as well as with client architects and business teams.

Job requirements
1. Agentic systems and AI workflows
- Design and build LLM agents that use tools and interact with enterprise systems and data
- Orchestrate multi-step and multi-agent workflows, with human validation and hand-off where needed
- Define clear boundaries for each agent through typed tool contracts, structured outputs, guardrails and access policies
- Connect agents to other systems through open protocols such as MCP and A2A, and through well-designed APIs
- Choose the most appropriate architecture for each problem, whether an agent, a deterministic workflow or a classical ML solution
- Evaluate AI solutions systematically against datasets to generate meaningful performance metrics.
2. Software Engineering for AI
- Write clean, modular, and well-documented code in Python (FastAPI, Pydantic, asyncio).
- Apply best practices in:
- Testing (unit, integration, end-to-end)
- CI/CD (GitHub Actions, GitLab CI, Argo CD)
- Observability (logging, monitoring, tracing).
- Ensure security and compliance (data protection, access controls, encryption).
- Integrate models and code into CI/CD pipelines for seamless deployment.
3. Enterprise AI & MLOps
- Deploy and monitor AI solution in production
- Design and implement MLOps pipelines for:
- Model training, fine-tuning, and evaluation
- Model versioning and lineage tracking
- A/B testing and canary deployments.
- Ensure scalability and reliability (auto-scaling, fault tolerance, disaster recovery).
- Collaborate with data engineers to build data pipelines (batch, streaming, real-time).
4. Collaboration & Technical Leadership
- Work closely with product owners, DevOps, and quality assurance in an agile, cross-functional team.
- Mentor junior engineers and promote best practices in AI/ML and software engineering.
- Translate product requirements into technical solutions and architectural decisions
- Document architectures, decisions, and best practices for internal and client-facing use.
- Develop relationships with internal and external stakeholders, including clients and partners.
5. End-to-End AI-powered Solutions Development (less frequent but can occur)
- Design, implement, and deploy distributed, high-volume, high-performance, low-latency machine learning solutions, with a focus on GenAI models, and especially LLM integrations and API-driven architectures.
- Take ownership of your models throughout their entire lifecycle:
- Data exploration and cleaning to build reproducible, versioned datasets
- State-of-the-art research to identify the best architectures for the problem (e.g., transformers, RAG, fine-tuning).
- Implementation, training, and optimization in reproducible environments
- Deployment, monitoring, and maintenance in production.
- Optimize models for performance, latency, and cost efficiency, especially in LLM serving and inference.
6. Innovation & Continuous Improvement
- Stay ahead of the latest AI and ML architectures (transformers, Mixture of Experts, sparse attention).
- Experiment with cutting-edge techniques (quantization, distillation, speculative decoding).
- Evaluate and benchmark open-source and proprietary models (Llama, Mistral, Mixtral, GPT-4, Claude).
- Bring your own ideas through vector8’s ideation process.
- Contribute to vector8’s AI accelerators (reusable components for common industry problems).
