About the job

Requirements
  • Extensive professional experience in software engineering, with a proven track record of shipping and maintaining production-grade Rust applications.
  • Production-level proficiency in Rust, including memory safety guarantees, lifetimes, asynchronous runtimes such as Tokio, concurrency models, and standard tooling including Cargo and Clippy.
  • Strong foundational knowledge of C# and .NET architectures to understand, reverse-engineer, and transition existing codebases.
  • Demonstrated ability to design complex, scalable software systems and define clear technical visions.
  • Ability to coach, mentor, and provide high-level technical guidance to engineering teams while navigating ambiguity.
  • Excellent interpersonal and English communication skills, with the ability to articulate complex technical roadmaps and collaborate across cross-functional spaces.
  • A bachelor's degree in Computer Science, IT, or a related technical field, or equivalent practical experience.
Responsibilities
  • Lead the strategic migration of legacy C# and .NET codebases, execution engines, and complex algorithms into highly optimized, safe, and concurrent Rust applications.
  • Design, develop, test, and maintain high-performance software components throughout the full software development lifecycle.
  • Define all aspects of development for the new stack, establishing coding standards, workflows, and appropriate build and continuous integration and continuous delivery environments.
  • Provide technical guidance, expertise, and coaching to developers, playing a central role in upskilling the team and building internal Rust expertise.

About the company

Roche is a global leader in pharmaceuticals and diagnostics. It develops medicines and diagnostic tools that help detect, monitor, and treat diseases, using research and biotechnology to drive new therapies and tests. Roche combines drug development with in-house diagnostic products to support personalized medicine, where treatments are tailored to individual patients based on test results. Its approach differs from many peers by integrating drug discovery with diagnostic capabilities and by expanding its research through strategic acquisitions (like Genentech) to strengthen its biotechnology and R&D capabilities. The company’s goal is to improve patient outcomes and healthcare worldwide by delivering reliable medicines, accurate diagnostic tests, and data-driven care.

Simplify's Take

What believers are saying

  • Enicepatide delivered 15.5% weight loss in September 2026 and 22.7% in June.
  • pTau217 can scale immediately through Roche's existing lab network and improve Alzheimer diagnostics.
  • Roche's June 2026 data and September 2026 filings signal multiple obesity shots on goal.

What critics are saying

  • Eli Lilly and Novo Nordisk dominate obesity pricing, distribution, and physician mindshare today.
  • Enicepatide remains Phase II-only; Roche starts late-stage glycemic and cardiovascular studies in 2027.
  • If enicepatide disappoints, Roche burns its $2.7 billion Carmot bet and loses obesity credibility.

What makes Roche unique

  • Roche combines pharma, diagnostics, and installed cobas labs across 4,500 U.S. instruments.
  • Elecsys pTau217 won FDA clearance on August 24, 2026, and CE marking September 7.
  • Roche controls obesity assets from Carmot and Zealand, spanning GLP-1/GIP and amylin.

FDA approves Roche's Tecentriq for stage III colon cancer, cutting recurrence risk by 50%

The US Food and Drug Administration has approved Roche's Tecentriq in combination with a fluoropyrimidine and oxaliplatin for adjuvant treatment of stage III deficient DNA mismatch repair colon cancer. This marks Tecentriq's twelfth approved indication in the US. The approval follows the phase III ATOMIC study, published in The New England Journal of Medicine, which demonstrated that Tecentriq plus chemotherapy reduced the risk of disease recurrence or death by 50% compared to chemotherapy alone. The 36-month disease-free survival rate was 86% with the combination versus 76% with chemotherapy alone. Nearly 25% of colon cancers are diagnosed at stage III, and almost one in three stage III patients experience recurrence within five years. This represents the first approved adjuvant immunotherapy regimen for this patient population. Roche is pursuing further regulatory filings, including with the European Medicines Agency.

Roche's enicepatide shows 22.5% weight loss in 48 weeks, challenging Eli Lilly and Novo Nordisk

Roche posted strong Phase 2 results for its weight loss drug enicepatide, showing 22.5% mean weight loss over 48 weeks. This compares favourably to Eli Lilly's Zepbound, which achieved 20.2% weight loss over 72 weeks in a separate trial. In another Phase 2 study, enicepatide demonstrated HbA1c reductions of up to 2.65 percentage points in diabetic patients after 48 weeks, compared to tirzepatide's 2.37 percentage points after 52 weeks. Despite promising results, Roche faces stiff competition from Novo Nordisk and Eli Lilly, which both have deep pipelines in development. Novo Nordisk's CagriSema is nearing approval, whilst Eli Lilly's retatrutide has posted strong Phase 3 results. Roche's revenue grew 6% year over year in the first half of the year to 30.4 billion Swiss francs.

Roche launches newborn screening test for SMA, SCID and sickle cell disease

Roche has launched a newborn screening test that simultaneously detects three severe genetic conditions: Spinal Muscular Atrophy, Severe Combined Immunodeficiency Disease, and Sickle Cell Disease. TIB MOLBIOL, a Roche subsidiary, developed the LightMix Newborn TREC/SMN1/HBB kit for use in countries accepting the CE mark. The test enables early detection before symptoms appear, allowing clinicians to initiate life-changing treatments sooner. Early intervention can prevent severe nerve damage in SMA, enable lifesaving bone marrow transplants for SCID, and drastically lower infant mortality in SCD through preventive measures. The IVDR-approved test provides a ready-to-use solution that integrates into existing laboratory workflows. It runs on established LightCycler systems, making it accessible for private and academic hospital laboratories across Europe.

Roche's Tam-Peli cuts death risk by 54% in Chinese SCLC trial, global phase III studies planned

Roche's collaborator MediLink has announced positive phase III results for tambotatug pelitecan (Tam-Peli) in Chinese patients with relapsed small-cell lung cancer. The TAISHAN-302 trial showed Tam-Peli reduced the risk of death by 54% compared to topotecan, with median overall survival of 13.3 versus 9.4 months. The antibody-drug conjugate also demonstrated superior progression-free survival (7.4 versus 2.8 months) and objective response rates (59.1% versus 9.7%). China's National Medical Products Administration has accepted the New Drug Application for filing. Roche is developing and commercialising Tam-Peli outside mainland China, Hong Kong and Macau, with plans to rapidly initiate global trials. The therapy has received Breakthrough Therapy Designations from both the US FDA and China CDE for relapsed small-cell lung cancer.

Tempus AI raises $600M to scale AI-enhanced liquid biopsy platform for cancer recurrence detection

Tempus AI has raised $600 million in Series C funding to scale its machine learning platform for cancer recurrence detection through liquid biopsies. The investment was led by SoftBank Vision Fund 2, with participation from Roche and Merck. Phase II trial data showed the AI-enhanced liquid biopsy analysis reduced false-negative results by 37% compared to conventional methods. The platform uses deep learning algorithms trained on over 12,000 genomic profiles to identify circulating tumour DNA fragments shed by residual cancer cells. A 2025 Nature Medicine study reported the system achieved 92% specificity in detecting minimal residual disease across breast, lung, and colorectal cancers. According to SEC filings, 45% of funds will support FDA pre-market approval trials, whilst 30% will fund global expansion into EU and APAC markets.
