Hands-On Chief Solutions Architect
Angular · Node.js · NestJS · AWS · Agentic AI
India — EU Shift (2PM-11 PM IST)— Full-Time(Remote)
About BigRio: BigRio is a Boston-based, remote-first technology consulting firm specializing in AI/ML, data engineering, cloud transformation, and custom software development. We partner with healthcare, life sciences, and enterprise organizations to2 PM design scalable, secure, and high-impact digital solutions. Our teams combine deep technical expertise with a strong consulting mindset to deliver measurable business outcomes.
About the Role: We are looking for a rare combination: a hands-on Solutions Architect who writes production-quality code every day and can walk into a client room, lead a discovery session, price an engagement, and draft a Statement of Work before the day is out. This is not a slide-deck architect role. You will own the technical direction of complex, AI-powered consulting engagements from initial scoping through delivery, working closely with US and EU clients as an embedded technical leader.
You will anchor your work on a modern Angular / Node.js / NestJS stack, deploy everything on AWS, and build next-generation Agentic AI platforms using LangChain, LLM orchestration, and RAG architectures. If you are energised by the intersection of deep engineering and client-facing consulting, this role was written for you.
What Makes This Role Unique
- You will code, architect, and consult — all three, every week.
- You will have direct relationships with US and EU clients and a visible seat at the table during pre-sales and delivery.
- You will shape how AI is used inside real enterprise products, not just prototype it.
- You will work with a globally distributed team that values craft, speed, and client trust equally.
Key Responsibilities
Technical Architecture & Engineering
- Design and implement scalable, production-grade solutions on an Angular / Node.js / NestJS stack, serving as the primary technical decision-maker on all active engagements.
- Write and review hands-on code regularly — this is a coding architect role; architecture without implementation ownership is not sufficient.
- Build and optimize Agentic AI systems including LangChain tool-based agents, RAG pipelines, LLM orchestration layers, and real-time streaming APIs.
- Design and manage AWS infrastructure including Lambda, API Gateway, DynamoDB, S3, SQS/SNS, ECS/Fargate, and related services.
- Use Prisma as the primary ORM for database schema design, migrations, and query optimization across PostgreSQL and other relational data stores.
- Establish and enforce engineering standards, code review practices, and architectural decision records (ADRs) across delivery teams.
Client Engagement & Pre-Sales
- Lead client discovery sessions, requirements workshops, and solution design conversations with confidence and clarity.
- Translate complex technical concepts into language that resonates with non-technical business stakeholders.
- Author and present Statements of Work (SOWs), including scope definition, effort estimation, resource planning, and commercial pricing for consulting engagements.
- Partner with sales and account management teams during the pre-sales cycle to shape technically credible proposals and demonstrate delivery capability.
- Build trusted long-term relationships with client stakeholders, acting as a go-to technical advisor beyond the immediate engagement.
Delivery & Agile Leadership
- Drive Agile delivery across engagements using Scrum or SAFe frameworks, serving as a technical anchor for sprint planning, backlog grooming, and retrospectives.
- Maintain Jira projects with well-structured epics, stories, and tasks that reflect real delivery progress and are accessible to both technical teams and client stakeholders.
- Use Confluence to document architecture decisions, runbooks, onboarding guides, and project wikis to a professional standard.
- Proactively identify and mitigate delivery risks, communicating scope, timeline, and quality trade-offs clearly and early.
- Mentor junior and mid-level engineers, providing technical guidance, code reviews, and career development support.

- Deep familiarity with LangChain, including tool-based agent architectures, memory management, prompt engineering, and LLM orchestration.
- Experience implementing RAG (Retrieval-Augmented Generation) pipelines with vector databases such as pgvector, Pinecone, or Weaviate.
- Understanding of LLM evaluation, cost optimization, and response quality tuning in a production environment.
- Familiarity with OpenAI GPT models, Anthropic Claude, or other frontier LLMs via API.
Consulting & Business Skills — Must-Have
- Demonstrated ability to write Statements of Work (SOWs) for consulting engagements, including effort estimation, resource planning, and commercial pricing.
- Strong client-facing communication skills in English — written and verbal — with the ability to lead meetings, present technical proposals, and build trust with senior stakeholders.

- ADR Writing
- CI/CD Pipelines
- GitHub / Git
Nice to Have
- Experience with NX monorepo architecture and micro-frontend patterns.

- Healthcare domain experience, particularly with claims, eligibility, or Medicare/Medicaid data.

- AWS certifications (Solutions Architect Associate or Professional preferred).
- Experience with Terraform or AWS CDK for infrastructure-as-code.
Work Schedule & Location
India-Based Remote Position
This role is based in India and operates on the EU shift to ensure meaningful overlap with both European and US-based clients and delivery teams. The required working hours are approximately 2:00 PM – 11:00 PM IST (Monday through Friday).
Candidates must be comfortable and committed to working these hours on an ongoing basis. Occasional early-morning or evening calls with US-based stakeholders may be required. Flexibility and reliability during core EU hours are non-negotiable for this role.
The Ideal Candidate: The person who thrives in this role will be someone who genuinely enjoys both the technical craft and the human side of consulting. They are as comfortable whiteboarding a NestJS microservice architecture as they are presenting a commercial proposal to a CTO. They take pride in clean, well-tested code and equally in clear, well-written documentation. They understand that great architecture means nothing if it is not delivered on time and communicated well.
Most importantly, they are someone a client trusts — not just because of their technical depth, but because of how they show up: prepared, articulate, proactive, and accountable.
