JOB POSTING
Associate Solution Architect
About Heystack
Heystack is a martech delivery consultancy. We design, architect and run customer engagement and personalisation platforms for brands, working across Bloomreach, Iterable, Klaviyo and Braze. We own the strategy, the architecture and the client relationship, and we care about doing the technical work properly, not just quickly.
Role Overview
This is a key hire as we build our solution architecture function, working directly with our CTO. You will start by running partner led onboardings (PLOs) for platforms such as Bloomreach and Iterable, fronting the standard onboarding sessions and guiding clients through setup and go-live. Alongside that you will take on the more technical work that sits beyond standard campaign delivery; data Integrations, data Feeds and troubleshooting, and grow into owning technical scoping and design as a full Solution Architect.
The PLOs are your training ground. They teach you the platforms inside out while keeping you close to clients. The technical retainer work is the destination.
Key Responsibilities
-
Lead partner led onboardings, fronting standard onboarding material and guiding clients from setup to go-live, with support from the wider team where needed
-
Configure platforms during onboarding: account setup, data, channels, templates and integrations
-
Take on technical retainer work, data feeds, API integrations and the more technical client requests our CRM team does not cover
-
Work side by side with our CTO, learning solution architecture on live projects
-
Translate client requirements into clear, workable technical solutions and document them
-
Grow into owning technical scoping, design and pre-sales input as you develop
About You - Essential
-
2+ years of experience in a client-facing technical role at a customer engagement, email, CDP or martech platform (support, onboarding, implementation or solutions)
-
Confident and personable in front of clients, comfortable leading a session and presenting standard material clearly
-
Solid grasp of how these platforms work: data structures, segmentation, channels and basic integrations
-
Comfortable with APIs and data feeds and good at troubleshooting, or a clear aptitude and appetite to go deeper fast
-
Self-starting and organised, able to run an onboarding with light support
-
Excellent communicator, able to break technical detail down for non-technical clients
Nice to have:
-
Hands on experience with one or more of Bloomreach, Braze, Iterable, Hightouch or Klaviyo
-
HTML, SQL, JSON and basic scripting (Python or JavaScript)
-
Experience with ETL, data pipelines or integration tooling
-
Familiarity with data warehouse concepts and tooling: Snowflake, BigQuery or Redshift
-
Mobile app development
Your Personality
Someone who does not need to have all the answers, but knows how to find them. You might not have ticked every box yet, but you pick things up fast, you are honest about what you do not know and you do not stop until you have figured it out. You embrace new tools and technology — including AI — not because it is expected but because you find it genuinely interesting. You read the docs, you experiment, you come back with solutions. We care far more about curiosity, drive and attitude than a perfect CV. If you have the right foundation and a hunger to grow, we will build the rest together.
Why Take the Leap & Interview Process
You will have real responsibility from day one and a development path you help shape, growing from onboarding delivery into full solution architecture, learning directly from our CTO. We move fast and we keep things lean, so your work lands quickly and your voice is heard.
We keep it straightforward but we do want to see how you think. After an initial conversation, you will complete a short practical exercise followed by a presentation to the team. The exercise is designed to reflect the kind of work you would actually be doing, technical scoping, data architecture or integration design, so there are no tricks, just a chance to show us how you approach a real problem.
