Siemens Digital Industries Software is a leading provider of solutions for the design, simulation, and manufacture of products across many different industries. Formula 1 cars, skyscrapers, ships, space exploration vehicles, and many of the objects we see in our daily lives are being conceived and manufactured using our Product Lifecycle Management (PLM) software.

This role is Technical Account Manager (TAM) with responsibilities as single post-sale technical owner of adoption and scale across the customer's footprint in the four products of the specialized GTM for Software, Data and AI — the ICX trio (Mendix, Graph Studio, AI Cloud) and SLC. The mission is to convert sold software into realized technical value and grow that footprint, account by account, holding only a basic understanding of the wider Siemens portfolio — enough to spot and route adjacent opportunities.

Advisor-first: guide adoption, drive the customer's software, data and AI teams to self-sufficiency, and own the architectural view of how these products fit their landscape. Build trusted relationships with senior customer stakeholders — CIO/CTO, enterprise architects and key business stakeholders — as the account's strategic technical advisor. Ring-fenced from owning commercial, support and delivery — contribute deep technical input on architecture and implementation, never the process.

Every TAM is a technical practitioner — hands-on capable and credible in the products and the customer's architecture, able to prototype and prove things in the tooling. How much a TAM builds themselves, versus pulls Specialists in for the heavy build, varies with their product depth and the account. Every TAM is also well trained in the use of generative AI in day-to-day work, applying it to work faster and raise the quality of their output.

A gated resource on designated accounts only (strategic designation, expansion potential or technical complexity — not ARR), spanning the industrial and non-industrial customer base; intensity scales with the stakes of the account. The TAM is the field's channel into the Product organization — the natural bridge to the Field CTO — carrying structured voice-of-customer upstream into the roadmap and roadmap context back. Primary technical contact for the account; never the commercial or retention contact.

A. Essential Functions

Technical Account Strategy & Planning
Build and maintain trusted relationships with key customer stakeholders — CIO/CTO, enterprise architects and key business stakeholders — as the account's strategic technical advisor.
Run joint technical account planning with the AE, Partner AE and Partner Manager; align adoption and footprint-growth priorities.
Maintain a current view of the customer's software architecture and landscape; advise how the four products integrate, partnering with customer-side and Siemens architects.
Translate the sold solution into a technical adoption roadmap aligned to the customer's software, data and AI strategy.
Responsible for capturing the above in a Customer Adoption Plan, and drive progress, collaboration and alignment based on that.

B. Adoption & Technical Execution

Run the technical kickoff with the customer's software, data and AI teams; turn the sold solution into an adoption plan and hand-shake with Expert Services on implementation.
Drive adoption enablement (workshops, office hours) toward customer self-sufficiency; run a recurring technical account-review cadence, tracking adoption health and surfacing risks early.
Get hands-on to prototype use-cases and lightly integrate to unblock rollouts — how much depends on your product depth and the account; pull Specialists in for heavy build.
Collaborate with Expert Services (Siemens or partner), who own implementation — align on adoption and surface needs, never own delivery.

C. Footprint Growth & Bid Support

Surface and shape new technical use-cases; design for the next workload and scale.
Spot opportunities across the four products and wider Siemens portfolio; route them to the account team and hand qualified commercial signal to the AE.
Contribute deep technical input on architecture and implementation to bids and RFx (typically expansion on covered accounts); the sales/bid team owns the process.

D. Internal Operations & Orchestration

Track adoption health and technical pipeline for covered accounts; contribute to account planning and internal reviews.
Orchestrate across AE / Partner AE / Partner Manager / Specialists / Expert Services; triage when to pull Specialists.
Use and promote internal tools to capture and reuse materials.

E. Knowledge Sharing & Mentoring

Build an internal knowledge network and share adoption best practices.
Contribute to adoption playbooks, reference architectures and supporting tools.
Coach and mentor other TAMs and team members.

F. Field Signal & Product Feedback

As the field's channel into Product, capture structured field signal from live adoption and feed it to the Field CTO; carry roadmap context back to the customer.
Represent the customer's technical needs and adoption blockers internally; escalate and advocate.

G. General - Uphold Siemens' integrity, culture, values and compliance (health, safety, quality); complete required administration including timely expenses; undertake other reasonable duties as required.

H. Outcomes & Measures - What a successful TAM delivers, per function area — outcomes, not activity.

Function area: Technical Account Strategy & Planning

Outcome (what good looks like): A current, shared technical account plan and architecture view the account team acts on

Function area: Adoption & Technical Execution

Outcome (what good looks like): Sold software reaches productive use; the customer's teams become self-sufficient

Function area: Footprint Growth & Bid Support

Outcome (what good looks like): New technical use-cases surfaced and qualified; expansion is technically de-risked

Function area: Internal Operations & Orchestration

Outcome (what good looks like): Account team, Specialists and Expert Services orchestrated without gaps or duplication

Function area: Knowledge Sharing & Mentoring

Outcome (what good looks like): Adoption know-how compounds across the team rather than living in one head

Function area: Field Signal & Product Feedback

Outcome (what good looks like): Structured field signal reliably reaches Product; customers see themselves in the roadmap

Role Interfaces

The TAM is the technical hub of the post-sale account team. It hands qualified expansion signal, adoption status and technical input to the Account Executive (who owns the commercial deal, negotiation and quota) and takes back commercial strategy and account priorities. It aligns adoption with Expert Services (Siemens or partner), who own implementation and delivery — never the TAM. It triages and pulls Specialists for deep engineering and heavy build, feeds adoption-health signal to Renewal Specialists (who own renewals and retention), and partners with Partner AE / Partner Managers on joint planning without managing the partner commercial relationship. It advises customer-side architects on how the four products integrate into their landscape without owning their architecture decisions, and is the standing bridge to the Field CTO, carrying field signal upstream and roadmap context back. The wider customer-success apparatus — QBRs, CSAT/NPS, success plans, upsell targets, renewals — sits with the AE, Renewal Specialists (and a CSM where engaged), never the TAM.

We welcome applicants who meet the following criteria:

A. Product & technical depth

Deep expertise in the adoption and account discipline
Adoption breadth across all four products
Hands-on technical capability — practitioner-level depth; able to prototype, demo and work in the products (required of every TAM; how much you build yourself varies by product depth and account)
Software, data & AI delivery practices
Wider Siemens portfolio awareness

B. Account & consultative

Technical account planning
Architectural advisory & landscape mapping
Senior stakeholder relationship management (CIO/CTO, enterprise architects, business stakeholders)
Customer enablement & facilitation
Footprint growth / use-case shaping
Technical input to bids & RFx

C. Ways of working

Orchestration & cross-team collaboration
Voice-of-customer / structured feedback capture
Communication & storytelling
Coaching & mentoring
Growth mindset & self-development
Skilled, day-to-day use of generative AI to work faster and improve quality

D. More hands-on (deployment-leaning) TAMs — additional

Deeper retained expertise in one product
Build and integrate more directly — spend more time hands-on and pull Specialists in less

Education & Experience

A relevant university degree (computer science, software engineering, data/AI or related) or equivalent practical experience.
A track record in post-sale technical roles — solution/adoption consulting, technical account management, solution architecture or forward-deployed engineering — with hands-on familiarity with modern software, data and AI delivery.
Depth in one or more of the four products is valued; breadth across them is built on the job. Genuine hands-on technical capability is required of every TAM — credible practitioners who can get into the detail, not relationship managers; the amount of build work expected varies by product depth and account. Level-specific requirements (years, depth, scope) are deferred to the future levelling pass.

Working Conditions

Normal office or home-office environment, with travel to customer sites as the account requires.
Must be willing and available to work the core hours required for the role and its account coverage.
