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 Platform Engineer with IoT, Python, and AWS experience to drive the design and development of the next generation of our multi-sided smart kitchen platform: the Fresco KitchenOS.

Reporting to the Engineering Manager for Platform & Firmware, you will work cross functionally designing/creating/deploying end-to-end platform capabilities and supporting production operations.

Your Responsibilities

Own and evolve ~20 Lambda-based microservices (Python 3.14, AWS CDK, aws-lambda-powertools) covering device control, cooking sessions, media, recipes, auth, and more
Design domain event patterns across services using EventBridge, SQS, and SNS
Own services end-to-end: ensuring correct schema design maintaining self-service deployment alerting on-call
Build AI/ML integrations using Google Generative AI, semantic search, and recipe understanding pipelines
Keep AWS spend honest: right-size memory/timeout configs, eliminate wasteful invocation patterns (noisy events, fat payloads, chatty calls), and flag cost regressions via Cost Explorer and Datadog before they hit the bill
Grow the team's skills through mentoring, knowledge-sharing sessions, and other technical initiatives.

Your Skills

5+ years building production AWS Lambda systems at scale, with deep AWS CDK (writing constructs, not just copy-pasting templates)
Fluent in Python with strict typing (pyrefly, Pydantic v2)
Comfortable across DynamoDB, Valkey (Redis), PostgreSQL (SQLModel/Alembic), and Elasticsearch
Strong AI engineering practice: AI tooling is a core part of your engineering workflow, and you can bring the team along on adoption.
Can read IoT/embedded protocol code (CBOR, KSUID, CRC) without panicking
Fluent in English; 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
Improve the shared abstractions others depend on (API Gateway, VPC, cache, DynamoDB tables) and drive direction through design docs and cross-team code review
Own infrastructure as code (AWS CDK + deployment pipelines), observability (Datadog APM, Lambda tracing, structured logging, alarms), and the on-call rotation
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?

We get a lot done by prioritizing well and being effective instead of busy. We care deeply about our customers and the product experiences we provide. We treat each other with respect, speak our minds, and always listen to each other—regardless of function or seniority. We are authentic, humble, and most importantly, trust each other to do a great job.

We offer competitive, market driven salaries, equity, a hybrid or remote working model, and much more.

Like with any good meal, a career at Fresco is both rich and rewarding, with many opportunities and room for growth. If you’re ready to serve up your best work at Fresco, get in touch!

What will you get?

The chance to work at a hyper-growth, venture-backed startup in a budding industry
The ability to feel true purpose in your work and generate success on a global platform
Competitive, market driven compensation
Meaningful share options as part of our Employee Share Option Scheme
A flexible hybrid model to suit you and your needs

Just like the ingredients in our kitchen, we believe that diversity of ideas is what makes the workplace great. Fresco is proud to be an equal opportunities employer, and we are committed to building a diverse and inclusive workplace. We welcome and encourage applications from candidates from a range of national, ethnic, or cultural groups.
