Presales Solution Architect - AWS

We're looking for a Presales Solution Architect to be the technical voice on our discovery calls and the engine behind our proposed solutions and SOWs. You'll work directly with founders, CTOs, and engineering leaders at US, UK, and EU clients to turn vague business goals into concrete AWS architectures — and turn those architectures into well-scoped, well-priced engagements that actually fit how Apex delivers. A large share of our pipeline is AI/ML work, so this isn't a pure infra role — it's where AWS, GenAI, and commercial scoping meet.

This isn't an order-taking role. We want someone who pushes back on bad ideas, proposes better ones, and builds client trust on the first call.

What you'll bring

• Deep AWS expertise across the Well-Architected Framework — compute, storage, networking, security, data services — and the ability to map customer problems to AWS-native architectures live, on a discovery call
• Strong technical scoping and discovery skills — leading client calls, pulling requirements out of notes and recordings, spotting gaps, and translating business goals into clear technical workstreams
• Familiarity with AWS funding programs (IW, MAP, POC, ProdReady) and how to align scope to them
• GenAI fluency — Bedrock, Nova, agentic patterns, RAG, voice and chatbot stacks, and the trade-offs between managed AWS AI services and third-party tooling
• Solid documentation — you can produce clean proposed solutions and SOWs with accurate effort estimates, team composition, pricing logic, and AWS service cost projections (AWS Calculator)
• Customer-facing comfort in English with founders, CTOs, and engineering leaders across US, UK, and EU clients
• Judgment to push back, propose alternatives, and build trust quickly — not default to "yes" mode
• Bonus: AWS Solutions Architect Professional cert, prior consultancy/agency presales experience, prior SOW ownership

What you'll do

• Lead technical discovery calls, often alongside founders or service line leaders
• Translate business goals into concrete technical workstreams aligned with AWS funding programs (IW, MAP, POC, ProdReady)
• Produce proposed solutions and SOWs in Apex's standard format — architecture, effort estimates, team composition, pricing, AWS cost projections
• Work across both pure-cloud and AI/ML scopes — Bedrock, Nova, RAG pipelines, agentic systems, voice and chatbot
• Push back on requirements that won't work, and propose better paths
• Partner with our Delivery Lead, service line leaders, and founders to make sure scope is actually deliverable
• Stay current on AWS service updates and AI/ML patterns relevant to our pipeline

Work setup

Fully remote, with the option for occasional in-person meetups (if you'd like). We work asynchronously across Budapest, London, and Seattle time zones — Central European working hours are the natural overlap.
