Senior Software Engineer, Platform (based in Dublin OR Madrid)

Job description

About Fresco Fresco is a smart kitchen platform trusted by leading appliance brands around the world to build and scale connected cooking experiences. Our platform helps brands launch faster, deliver better experiences for home cooks, and accelerate their digital transformation. Our mission is to empower anyone to cook delicious food. Powered by KitchenOS and the Fresco AI Cooking Companion, Fresco connects appliances across brands, supports rapid onboarding, and scales globally in more than 15 languages. We work with partners including Panasonic, Middleby, Kenwood, Instant Pot Brands, Bosch, GE Appliances, Arda and LG, and operate as a global team with offices in Dublin and Madrid. About the Role Fresco is looking for a senior engineer to help drive the design and evolution of KitchenOS, our multi-sided smart kitchen platform. This is a deep-IC, design-first role: working alongside a strong platform team, you'll help shape how ~20 event-driven microservices fit together, make the architecture calls that keep them fast and cheap to run, and raise the abstractions the whole team builds on. Strong AWS and fluent Python are essential, but the thing that sets this role apart is a system-design mindset: you think in services, events, and trade-offs, not individual functions. You'll report to the Engineering Manager for Platform & Firmware and work cross-functionally to design, build, and ship end-to-end platform capabilities. Your Responsibilities Shape the architecture of ~20 Lambda-based Python microservices (Python 3.14, aws-lambda-powertools) spanning device control, cooking sessions, media, recipes, and auth. Design domain event patterns across services with EventBridge, SQS, and SNS, choosing delivery semantics and sync vs async fan-out deliberately, and challenging designs that don't earn their keep. Own schema and API design, and improve the shared abstractions the whole team depends on (API Gateway, VPC, cache, DynamoDB tables). Drive direction through design docs and cross-team code review. Stay close to your services after they ship. Ownership is shared across the team, so like everyone here you'll take part in the on-call rotation for what you build, supported by self-service deployment and alerting. Design for cost. Fold efficiency into architecture decisions: right-size memory/timeout, avoid noisy events, fat payloads and chatty calls, and catch cost regressions early via Cost Explorer and Datadog. Grow the team's skills through mentoring, knowledge-sharing sessions, and other technical initiatives. Your Skills Typically 5+ years designing and building backend systems at scale, with significant time on AWS, spanning services, events, and architecture trade-offs, not just individual functions. We care more about the depth of what you've designed than the exact year count. Strong infrastructure-as-code ownership. We use AWS CDK (writing constructs, not copy-pasting templates); deep Terraform experience transfers well and is equally welcome. Fluent in Python with strict typing (Pydantic v2, pyrefly). Comfortable across DynamoDB, Valkey (Redis), PostgreSQL (SQLModel/Alembic), and Elasticsearch. Strong AI engineering practice: AI tooling is a core part of your workflow, and you can bring the team along on adoption. Can read IoT/embedded protocol code (CBOR, KSUID, CRC) without panicking. Fluent in English; a clear communicator with both technical peers and less-technical stakeholders. How You’ll Work Senior IC: deep technical ownership and influence through code, design, and review, not people management. Make deliberate architecture trade-offs (event delivery semantics, on-demand vs provisioned, cold-start vs reserved concurrency, sync vs async fan-out) and challenge infrastructure that isn't earning its keep. Own infrastructure as code (CDK or Terraform + deployment pipelines) and observability (Datadog APM, Lambda tracing, structured logging, alarms) for what you build. Share the on-call rotation; everyone owns what they ship. Engineering hygiene: strict typing, unit tests, Python tooling via uv, ruff, pyrefly, and Poe. Nice to Have Multi-tenant SaaS platform experience LLM integration (prompt pipelines, structured extraction) Appliance/IoT protocol knowledge What's it like working at Fresco?
