We're hiring a Solutions Architect to design the systems behind the products Bolder Apps builds for US-based clients. You'll be the technical lead in the room from the first discovery call. You'll turn a client's idea into an architecture, a scope and a plan our engineering team can build. This is a design and review role, not a coding seat. You won't write production code. You'll guide the dev team, review their code and architecture, and own technical quality from kickoff to launch, so what ships matches what was designed. Our projects cover web, mobile and AI products. Many have multi-tenant setups, lots of third-party integrations and real privacy and security needs. This is a contract role, paid hourly and fully remote. It is open to people based in the countries listed in this post, with overlap into US Eastern time for client calls. If you've designed and shipped client products at an agency or consultancy, and you can explain a trade-off to a founder as clearly as to an engineer, we want to talk.

About Us
Bolder Apps is a product development studio that partners with US-based startups and established companies to build and scale innovative digital products. We specialize in AI-powered development, full-cycle product creation, and engineering team augmentation. Our mission is simple: build bolder, faster, and smarter.
Our Culture & Values (read before applying)
We move fast. We take ownership. We work with AI, not against it. And we expect everyone to bring ideas, not wait for instructions.
There are no daily checklists, no micromanagement, and no corporate politics. Instead, you'll have autonomy, trust, and a team that's always ready to help you grow. At Bolder Apps, impact matters more than titles, and curiosity matters more than seniority.
If you want a place where you can level up fast and actually see your work making a difference - welcome aboard.
Responsibilities
Lead technical discovery with clients. Ask the right questions, find the real constraints and turn a rough idea into a clear solution design
Design the system architecture for web, mobile and AI products. Services,



data model, hosting and how the pieces talk to each other
Write the technical parts of proposals and scopes of work. Modules, user flows, acceptance criteria, edge cases and estimates the team can stand behind
Design integrations with third-party APIs and vendors. Plan for retries, queues, webhooks and monitoring, and keep a clean way to swap a provider later
Plan multi-tenant and white-label setups with proper data isolation and access control
Build security and privacy in from day one. Encryption, audit logs, consent, data residency and the evidence clients need for an outside audit
Design AI and LLM features for client products, including model choice, retrieval (RAG), guardrails and the evaluations that prove quality in production
Plan in phases. Ship a lean MVP first and keep the design ready for the full build without a rewrite
Work with sales and project managers on scope, timelines and risk. Push back early when something will not fit
Review the dev team's code, pull requests and technical approach. Catch drift from the design early and explain what to change
Guide and unblock engineers, set technical standards, and own technical quality through delivery and handover
Keep the architecture docs current so anyone on the team can pick up the context
Requirements
5+ years in software engineering, with at least 2 years designing systems as a solutions architect, technical lead or similar
Agency, consultancy or studio background. You've designed for several clients at the same time and you can switch context without losing quality
You've owned the architecture of client products that went live with real users. Diagrams that never shipped don't count




Strong backend and data fundamentals. You've designed APIs and relational data models (Postgres or similar) and you know where they break
Cloud architecture experience on AWS, Azure or GCP, including containers, deploys and monitoring
Real integration design experience. Third-party APIs, webhooks, SSO and OAuth, background queues and failure handling
Hands-on AI architecture. You've designed LLM or RAG features with evaluation for production client products, and you know what they change about cost, latency and testing
Strong code and architecture reviewer. You can read a pull request, spot when it drifts from the design and explain the fix to the engineer
Comfortable running client-facing technical calls. You can explain a trade-off to a non-technical founder in plain words
You write clear technical scopes with estimates the team actually hits
AI-augmented workflow. You use AI tools every day in your own design, review and writing work
Excellent written and spoken English. Clients read your documents and hear your voice directly
Available for live client calls during US Eastern business hours
Nice to have
Multi-tenant SaaS, row-level security or white-label deployments
Products with strict privacy or compliance needs, such as sensitive personal data, data residency rules or third-party security audits
Mobile architecture (React Native or Flutter)
Comfortable reviewing TypeScript and Node.js (NestJS or similar) and React or Next.js code
E-commerce platforms such as Shopify
Mentoring engineers and setting technical standards for a team
Benefits
Contract role, paid hourly, fully remote, with overlap into US Eastern time for client calls
A wide mix of web, mobile and AI products for the US market
Steady pipeline of client work as part of a growing team
Real ownership over technical design, with no rigid playbook
Direct line to decision-makers, no extra layers between you and the people who own the outcome
A peer network of engineers, designers and PMs working on overlapping projects
